1. INTRODUCTION

SAFETY IS PRIORITY ONE 

Obviously, your first concern should be safety. Your vehicle was designed to be used primarily to 

carry passengers and cargo. Always remember that towing a trailer places additional loads on your 

vehicle’s engine, drivetrain, suspension, steering, braking, and other systems. Therefore, be certain 

that your vehicle can meet the demands of the towing application you have in mind. 

 

Rent or purchase only the highest-quality towing and safety equipment you can find. Reinforced tow 

hitches designed especially for certain Infiniti vehicles are available from your Infiniti dealer. 

Hitches for other Infiniti models — if applicable — should be bought from and installed by a 

professional supplier of towing equipment.  

 

Finally, it is important to follow the towing capacity limit set for your specific vehicle and to ensure 

that your vehicle is in top mechanical condition, especially the tires, brakes, suspension, and 

engine cooling system. See your vehicle owner’s manual for details. 

 

NEVER EXCEED THE ESTABLISHED TOWING CAPACITY 

Towing capacities vary from vehicle to vehicle. See the SPECIFICATIONS section of this guide for the 

towing capacities of 2010 Infiniti vehicles produced at the time of Towing Guide publication. Use 

this data to help select the proper Infiniti vehicle to meet your anticipated towing needs, and refer 

to it when renting a trailer or other piece of towing equipment.  

 

EQUIP YOUR INFINITI FOR TOWING 

The frequency and type of towing should influence the manner in which you equip your vehicle. If 

you plan to tow often, either for recreation or work, select the engine size, transmission type, 

suspension, and towing capacity that are best suited to your requirements. This guide can help you 

select that equipment.  

 

If, on the other hand, your towing will be infrequent, choose the Infiniti vehicle and equipment that 

best meets your day-to-day needs. Be careful not to exceed the towing capacity on those few 

occasions when you do tow.   

 

READ THIS GUIDE BEFORE YOU TOW 

This guide was designed to provide an overview of safe towing practices. Here, you will find 

information on towing equipment, safety, proper loading and driving techniques, towing tips, and 

much more. 

 

It is also a good idea to discuss your towing requirements with either your Infiniti dealer or a 

professional supplier of towing equipment before you equip your Infiniti vehicle for towing.

Finally, there are state and local laws on towing that you should review to ensure compliance with 

all regulations.

2. TOWING EQUIPMENT

RENTING 

The first thing to keep in mind when renting a trailer is to rent only from professional companies 

that specialize in towing and towing equipment. More than likely, specialized companies hire 

professional staff that can assist you in selecting and installing the proper towing equipment for 

your Infiniti vehicle. 

 

When renting, make sure you have your vehicle owner’s manual on hand so that you can reference 

the towing capacities for your specific vehicle. Never rent a trailer that exceeds these capacities, 

and make sure that any related towing equipment you rent will be sufficient for the loaded trailer. 

 

While you are there, ask questions. How much does the empty trailer weigh? How much weight will 

the trailer hold? What is the trailer’s tongue load? With what type of brakes is it equipped (if any)? 

All of these factors have an effect on whether your Infiniti vehicle is capable of safely pulling that 

type of trailer or piece of equipment. 

 

Make certain that the trailer stoplights, taillights, turn signals, and brakes (if equipped) are 

connected and are operating correctly, and that all safety equipments are properly installed. Check 

the safety chains/cables, tie-downs, etc.  

 

For safer operation, carefully inspect the condition of the trailer and towing equipment. Specifically, 

check to make sure the tires are not worn excessively and are properly inflated. Make sure there are 

not any broken welds, missing bolts, and that the hitch components are not damaged.   

 

Towing safety should be a high priority when choosing and renting towing equipment, including 

hitches.NEVER RENT A CLAMP-ON-TYPE HITCH. Your vehicle’s bumpers are not designed for using 

this type of hitch. Using it will damage your vehicle and could even result in the trailer separating 

from the towing vehicle; this can cause death or serious injury. To avoid this, use only a permanent- 

type hitch.  

 

PURCHASING 

If you are buying a travel or boat trailer, be sure that your Infiniti vehicle has the towing capacity to 

pull it. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual for 

detailed information regarding the towing capacity of your specific vehicle. Your vehicle owner’s  

manual should ALWAYS be referenced before making any towing decisions.  

 

Naturally, you will want to buy the highest-quality equipment you can find for maximum towing 

safety. And if you plan to tow often, consider convenience. Quick-disconnect trailer light connectors 

and ratchet-type tie-downs, for example, make the job go faster and easier and are usually worth 

the extra small investment. Purchase towing items such as hitches and hitch balls only from your 

Infiniti dealer or a professional supplier of towing equipment. 

 

If you are intending to use your vehicle to tow a trailer you already own, you must ensure that your 

loaded trailer remains well within your vehicle's towing capacity as specified in the vehicle owner's 

manual. In addition, you should purchase the right type, style, and class* of hitch and towing 

equipment to properly adapt the trailer to your vehicle.

3. WHAT IS RIGHT FOR YOU 

 

TYPES OF EQUIPMENT 

Towing requires a variety of equipment, and, depending upon the application, there can be several 

types or styles of each piece of equipment. Working with your Infiniti dealer or a professional 

supplier of towing equipment, it should be relatively simple to determine the proper type of 

equipment for your specific vehicle given the intended application. This section explains the most 

common pieces of towing equipment available.  

 

HITCHES 

Whichever type of hitch you use, it should be firmly bolted to your vehicle, and should be of the 

appropriate weight class for the equipment you intend to tow. In addition, keep the following in 

mind: 

 
Do not modify the vehicle’s braking or exhaust systems or its body structure/frame when 

installing the hitch.  

Installing an aftermarket hitch may affect the rear crash performance of your  vehicle.  

Be sure that the hitch does not interfere in any way with the vehicle’s impact-absorbing bumper.  

Regularly check to see that all hitch-mounting bolts are securely fastened.  

For receiver-type hitches using a ball mount, the ball mount should be removed when not 

towing. 

If you install a hitch yourself, remember that it must be securely attached to the frame or 

underbody, according to the manufacturer’s instructions. Never attach a hitch or towing device 

to the vehicle axle housing. This may damage the housing, wheel bearings, wheels, or tires.  

 

*See the SPECIFICATIONS section of this guide for equipment class information specific to your vehicle.


Hitch Types 

Bumper Hitch – This is a special reinforced bumper designed to accommodate a hitch ball.  

 

Receiver Hitch – A receiver hitch is bolted directly  to the vehicle structure for added strength and durability. Infiniti bolt-on receiver hitches are designed specifically for Infiniti vehicles and include the necessary reinforcements, with ample clearance around bumpers, frame members, etc. These hitches allow for the removal of the ball mount when not towing.


Clamp-On Bumper Hitch – This is a temporary hitch that clamps onto the bumper assembly. DO NOT USE this type of hitch on any Infiniti vehicle because using it may result in the trailer separating from the towing vehicle; this can cause death or serious injury. Use of this type of hitch can also damage the towing vehicle. 

 

Weight-Distributing Hitch System – This type of system uses a “load-leveling” or “equalizing” hitch. The weight- distributing feature helps shift the trailer tongue weight to all trailer tires and the tow vehicle front tires.   

 

For QX56 vehicles, a weight-distributing hitch ball mount (Class IV) is recommened if you plan to tow trailers with a maximum weight over 5,000 lbs. This ball mount includes a 2 5/16” hitch ball rated for up to 10,000 lbs., and is available through your Infiniti dealer. NOTE – A weight-distributing hitch system may affect the operation of trailer surge brakes. If you are considering use of a weight-distributing hitch system with a surge brake-equipped trailer, check with the surge brake, hitch, or trailer manufacturer to determine if and how this can be done. Follow the instructions provided by the manufacturer for installing and using the weight-distributing hitch system.


BALL MOUNT  

A ball mount (also known as a drawbar) is a bar that holds a hitch ball and is inserted into a 

receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000 lbs., etc.) 

and sizes (1 1/4”, 2”, etc.), and can be weight-distributing or non-weight-distributing.   

 

HITCH BALL 

A hitch ball is bolted through a ball mount or a hitch hole 

in the tow vehicle’s rear bumper. The coupler on the 

trailer tongue attaches over the hitch ball. 

 

Like ball mounts, hitch balls are available in a number of 

weight capacities and sizes. Always make sure the hitch 

ball selected has the proper shank diameter and weight 

rating for the ball mount as well as the coupler on your 

trailer. Using a 1 7/8” hitch ball in a 2” coupler, for example, could result in the trailer separating 

from the tow vehicle.  

 

The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The shank 

should be no more than 1/16” smaller than the hole. 

 

To keep the hitch ball in top condition, a simple maintenance routine is recommended.  Coating it 

with light grease will minimize wear of both the coupler and hitch ball. Also, by removing the hitch 

ball when not towing, or by protecting it with a special cover, you will help prevent rust from forming 

on it.

TRAILER TONGUE 

The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it also carries 

the coupler assembly. Knowledge of the trailer tongue load is critical as it can have a significant 

effect on the handling of the tow vehicle. See the SPECIFICATIONS section of this guide or refer to 

your vehicle owner’s manual to view the maximum trailer tongue load listed for your vehicle.  

 

SAFETY CHAINS/CABLES 

Always use suitable safety chains/cables between the tow vehicle and the trailer. If the hitch 

should break or become disengaged for some reason, these chains/cables will provide an 

emergency connection between the vehicle and the trailer. 

 

The chains/cables should be crossed under the 

trailer tongue and attached to the hitch or 

vehicle frame. Crossing the chains/cables under 

the tongue will help prevent the tongue from 

hitting the ground should the trailer become 

disconnected.  

 

Be sure to leave enough slack in the 

chains/cables to turn corners without binding; 

however, note that excessive slack will allow the 

chains/cables to drag on the ground.  

 

Do not use S-hooks for attaching, as they may 

become un-hooked and are illegal in many 

states.  

 

To avoid damage to the bumper and chains/cables when making a sharp turn, do not attach the 

chains/cables too close to the coupler.  Consult your trailer manufacturer for the proper location of 

the chain/cable attachment to the trailer. 

 

REAR VIEW MIRRORS 

In many cases, a trailer can block your rear vision when you are using only the standard Infiniti rear 

view mirrors. These mirrors were not designed for towing. “Extended” mirrors specifically designed 

for trailer towing should be used when your rearward vision is obstructed. Before using these 

mirrors, make certain that they comply with state and local regulations. Telescoping Tow Mirrors are 

available as an accessory for QX56 vehicles. Contact your Infiniti dealer for details. 

 

SWAY CONTROL DEVICE 

Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.  

Sway control devices may be used to help control these effects. If you choose to use one, contact a 

reputable trailer hitch supplier to make sure the sway control device will work with the vehicle, 

hitch, trailer and the trailer’s brake system. Follow the instructions provided by the manufacturer for 

installing and using the sway control device. 

 

BREAKAWAY SWITCH 

On a trailer with electric brakes, a breakaway switch can automatically activate the trailer brake 

system if the trailer becomes separated from the tow vehicle. Should the trailer become detached, 

a breakaway switch may help prevent the trailer from wandering into another lane.  

 

A breakaway switch relies on the power of a trailer battery, so make sure it is not discharged. Never 

use the breakaway switch to “park” the trailer on a grade. The battery would eventually discharge 

and release the brake, allowing the trailer to roll. 

 

Be sure to leave enough slack in the tether on the breakaway switch to turn corners without 

binding.  If you do not, the electric trailer brakes will lock-up and not release. See your trailer 

manufacturer for proper installation of a breakaway switch that is compatible with your trailer 

braking system. 

 

TRAILER LIGHTS 

Trailer lights should comply with all applicable federal, state, and local regulations, and should be 

in proper working order at all times. A trailer’s taillights, stoplights, and turn signal lights must be 

wired into the towing vehicle’s electrical system.* 

 

Most trailers operate on a four-wire system in which the stoplights and turn signal lights utilize the 

same wire. All Infiniti vehicles have separate wires for the stoplights and turn signal lights, 

therefore a device called a “converter” is needed.** Specifically, a “powered converter” must be 

used, as a converter of this type creates only minimal additional electrical demand (draw) on the 

vehicle lighting circuits, which helps to ensure protection for the vehicle’s sensitive electronics. 

 

Always check for correct operation of the taillights, stoplights, and turn signal lights every time you 

connect a trailer for towing. Never replace vehicle fuses with fuses of a higher amperage rating than 

the original. 

 

*Vehicles equipped with LED taillights require that wiring be connected at a specific location. For assistance in  

  hooking up trailer lights, contact your Infiniti dealer or a professional supplier of towing equipment. 

**QX56 vehicles are pre-wired for trailer lighting and do not require a converter.

NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 

Use only an Infiniti approved wiring harness, or consult your dealer or a professional supplier of 

towing equipment for compatible equipment.  

 

BRAKES 

As with hitches, several types of braking systems are available. Most states require a separate 

braking system on trailers with a loaded weight above a specific amount, therefore you should 

check to ensure you comply with all regulations. Have a professional supplier of towing equipment 

demonstrate proper brake function testing. 

NOTE – Never connect a hydraulic trailer brake system directly to the vehicle hydraulic brake 

system.  

 

Surge Brakes – The surge brake actuator is mounted on the trailer tongue with a hydraulic line 

running to each trailer wheel. Surge brakes are activated by the trailer pushing against the hitch 

ball when the tow vehicle is braking. Hydraulic surge brakes are common on rental trailers and 

some boat trailers. In this type of system, there is no hydraulic or electric connection for brake 

operation between the tow vehicle and the trailer. 

 

Electric Trailer Brakes – Electric braking systems are activated by an electronic signal sent from a 

trailer brake controller (special brake-sensing module).  

 

If electric trailer brakes are used, Infiniti recommends all-electronic actuation because with this 

system it will not be necessary to tap into the tow vehicle’s hydraulic system.  

 

For your convenience, QX56 vehicles are pre-wired to accommodate most popular electric trailer 

brake controllers. A wiring harness* is either included with your vehicle or available from your 

Infiniti dealer.  This harness provides electric trailer brake controller input and output connections 

to the vehicle wiring. See a professional supplier of towing equipment for trailer brake controller 

availability.  

NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 

Use only an Infiniti approved wiring harness, or consult your dealer or professional supplier of 

towing equipment for compatible equipment.

designed to assist you with your towing needs.  

 

Contact your Infiniti dealer for more information on accessories or towing-related parts for your 

Infiniti vehicle.

4. PREPARING YOUR VEHICLE  

BREAK-IN AND MAINTENANCE SCHEDULE 

Infiniti recommends that you allow a sufficient “break-in” (500 miles) of both the engine and drivetrain before towing with your new Infiniti vehicle. In addition, for the first 500 miles that you tow a trailer, do not drive over 50 mph and do not make starts at full throttle.  

 

Keep in mind, too, that towing places higher demands and added loads on vehicle components, so more frequent maintenance is called for. Your Infiniti Service & Maintenance Guide provides the accelerated maintenance schedule for towing purposes. Engine oil, filter, transmission oil, and possibly other fluids should be changed more frequently when towing. 

 

TIRE PRESSURE 

When towing a trailer, increase the tow vehicle tire pressures to the recommended cold specifications. You will find these figures in the vehicle owner’s manual and on the tire pressure chart located within the vehicle. Trailer tire condition, size, load rating, and inflation pressure must be in accordance with the trailer and tire manufacturer’s specifications. 

 

MEASURING VEHICLE WEIGHT 

The key to safe, efficient towing has to do with weight. Your vehicle — SUV, crossover, or passenger car — is capable of carrying and towing only a certain amount of weight. You must compare your vehicle’s tow weight ratings with the combined weight of the vehicle, trailer, and their contents. This will help ensure that the total weight does not exceed any of your vehicle’s tow weight ratings. There are four weights to consider when towing:  

Gross Vehicle Weight 

Gross Axle Weight (Front and Rear) 

Gross Combined Weight 

Trailer Tongue Load


These ratings are based upon normal highway driving and may be reduced if operating in reduced- traction situations, for example, slippery boat ramps. 

 

NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and the trailer tongue load specified could adversely affect vehicle handling, braking, and performance. Damage to your vehicle resulting from overloading may not be covered by your vehicle warranty. 

 

GROSS VEHICLE WEIGHT (GVW) 

The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo, fuel, hitch, trailer tongue weight, and any optional equipment.  

 

The best way to determine the GVW is by having the vehicle — loaded and ready to tow — weighed at a public scale. To that figure, add the combined weight of all passengers. Then, add the trailer tongue weight to determine the approximate GVW.  

 

The GVW you come up with must not exceed the Gross Vehicle Weight Rating (GVWR) for your vehicle. On all Infiniti vehicles, the GVWR is shown on the Federal Motor Vehicle Safety Standard (F.M.V.S.S.) certification label located in the driver’s-side door area.  

 

To avoid overloading the vehicle, be sure to include the trailer tongue weight as a part of the cargo when determining how much weight can be safely carried inside the vehicle. The weight of the roof rack cargo should also be included. 

 

GROSS AXLE WEIGHT (GAW) 

The Gross Axle Weight (GAW) is the maximum weight each axle (front and rear) is designed to safely carry.  

 

To determine the GAW, load the vehicle as you would for towing and attach the loaded trailer. At a public scale, with the loaded trailer attached, place only the tow vehicle front wheels on the scale to determine the actual front axle GAW. To obtain the rear axle GAW, place all four tow vehicle wheels on the scale. From that figure, subtract the front GAW and you will have the rear GAW amount.  

 

The GAW you come up with must not exceed the Gross Axle Weight Rating (GAWR) for your vehicle. On Infiniti vehicles, the GAWR for both axles is listed on the F.M.V.S.S. certification label.  

 

GROSS COMBINED WEIGHT (GCW) 

The Gross Combined Weight (GCW) is the total weight of the tow vehicle with all passengers, cargo, and fuel, plus the total weight of the trailer and all its cargo.  

 

To determine the GCW, simply weigh your vehicle when fully loaded and ready to tow, and add in the weight of the loaded trailer.  

 

The GCW you come up with must not exceed the Gross Combined Weight Rating (GCWR) for your vehicle. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to view the GCWR listed for your vehicle.   

 

TRAILER TONGUE LOAD 

Trailer tongue load is the amount of weight pressing down on the tow vehicle hitch.  

 

To measure trailer tongue load, place the tongue of the trailer on a scale when the trailer is not attached to the vehicle. A separate vehicle jack — not the trailer jack — should be used, as the location of the trailer jack is rearward of the trailer tongue and will not give you an accurate measurement of the true tongue load. Make sure the vehicle jack is placed directly under the trailer tongue coupler, and the tongue is set at the height/level of the tow vehicle hitch.  

 

For proper handling, you must keep the trailer tongue load between 10-15% of the actual trailer weight, within the limits of the maximum trailer tongue load allowable. For example, to determine the proper trailer tongue load for a 1,500-lb. trailer, multiply the weight of 1,500 lbs. by 10% to arrive at a figure of 150 lbs.  

 

Some trailer types may require different trailer tongue loads for safe towing. Always follow the trailer manufacturer’s recommendations for proper trailer set-up and trailer tongue load. Keep the trailer tongue load within the maximum trailer tongue load allowable. Additionally, make sure the vehicle has the payload capacity available for the trailer tongue load.  

 

See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to view the maximum trailer tongue load listed for your vehicle.  

NOTE – The vehicle weight ratings (GVWR, GAWR, GCWR, etc.) must not be exceeded, regardless of trailer or hitch type. 

 

HITCH & TRAILER HEIGHT 

It is important that your trailer floor and tongue ride as level as possible. This  will help prevent over-angling, bottoming-out, and improper load transfer. Therefore, the hitch or trailer tongue must be adjusted during the initial vehicle/trailer fit-up to ensure a level ride. Ball mounts are available in different configurations to adjust the hitch ball height.


5. TOWING SAFETY 

Towing can significantly alter the handling and performance characteristics of your vehicle. Plus, it 

puts increased strain on the engine and drivetrain. Therefore, it is always a good idea to approach 

towing from the standpoint of safety — whether you are purchasing equipment or actually pulling 

the trailer.  

 

Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to tow. Buy or 

lease only quality equipment. In addition, be certain that you have all of the equipment needed for 

safe towing, such as safety chains/cables, electric trailer brakes, electric trailer brake controller, 

breakaway switch, and extended rear view mirrors.  

 

You should follow a more frequent maintenance schedule and check fluid levels, pressures, tire 

condition, etc., more often when on the road. See your vehicle owner’s manual for details. 

 

LOADING YOUR TRAILER 

Taking the time to load and balance your trailer properly will improve overall handling and minimize 

the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing from side to side, 

upsetting vehicle handling. Careful loading and balancing can help eliminate these problems. 

 

As mentioned earlier, trailer tongue load must fall between 10-15% of the total trailer weight, or 

within the limits of the maximum trailer tongue load specified by the trailer manufacturer. Excessive 

trailer tongue load can actually push down the vehicle in back, lifting the front wheels to a point 

where traction, steering response, and braking are severely reduced. Insufficient trailer tongue load 

can cause instability, which may lead to “tail wagging” or jackknifing. 

 

With this in mind, proper loading is extremely important. When loading a trailer, 60% of the total 

cargo weight should be positioned in the front portion of the trailer and 40% in the back. Then the 

load should be adjusted until the proper tongue load ratio is achieved.  

 

The trailer load should be balanced equally from side-to-side. Unequal side-to-side loading can 

negatively affect handling and braking. Once in place, all cargo should be firmly secured to prevent 

shifting. If the load should shift abruptly during braking or cornering, it could quickly affect the 

handling of your vehicle and cause a very unsafe situation.  

 

Finally, do not carry flammable materials, such as gasoline, in your trailer. In the event of an 

accident, an explosion or fire could occur. 

 

ENSURING VEHICLE/TRAILER STABILITY 

Improper loading, excessive or insufficient trailer tongue load, overloading, excessive trailer 

weight, poorly designed trailer suspensions, crosswinds, and poor maintenance are all things that 

can affect the stability of your vehicle and trailer combination. 

 

If swaying does occur, check the cargo load for proper balance and distribution to ensure proper 

trailer tongue load. In addition, check the condition of the suspension and shocks, as well as the 

tires, tire pressures, and wheel bearings on both the tow vehicle and trailer.  

 

If the swaying continues and your trailer is suitably balanced and within the towing capacity limits 

of your vehicle, discontinue towing and consult your Infiniti dealer or trailer manufacturer to 

determine the problem.  

 

VEHICLE SPEED 

Please note that some states have specific regulations and speed limits for vehicles that are towing 

trailers. Remember to reduce your speed in unsafe or less-than-ideal road conditions or weather. 

When towing a trailer, braking distances increase while handling agility decreases. Always leave 

yourself an extra margin of distance to respond to emergency situations. 

 

PASSENGERS 

Never allow passengers to ride inside a trailer while it is being towed. Not only is this unlawful in 

most areas, passengers could be seriously injured during sudden trailer movement or in an 

accident. In addition, trailers may allow fumes from the tow vehicle to leak inside. This could result 

in carbon monoxide poisoning from the engine exhaust. 

 

VEHICLE MODIFICATIONS 

Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, and 

necessary cooling system upgrading — are not recommended for any Infiniti vehicle being used for 

towing purposes. Changes to the drivetrain, suspension, exhaust systems, frame 

structure/unibody, or other vehicle components are not necessary for towing within the limits 

described in this guide. These changes may diminish the reliability and longevity of your vehicle 

and possibly void warranty coverage. 

 

TOOL KIT 

When towing, bring tools including flares, a flashlight, emergency reflectors, jumper cables, extra 

fuses, extra radiator coolant, oil, and easily replaced spare parts such as taillight bulbs. You should 

also carry spare tires for your tow vehicle and trailer, as well as a jack suitable for use on the trailer. 

Be aware that not all automotive jacks can be used safely on a trailer. 

 

BEFORE STARTING OUT 

Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are the tire 

pressures correct? Are the safety chains/cables securely in place? Is the cargo tied down securely? 

Do all the lights work? Is the coupler properly attached over the hitch ball and secured using a 

locking pin? Is the breakaway switch hooked up and functioning properly? Are vehicle and electric 

trailer brakes working properly?  

 

Make a checklist of key items to be inspected. When towing, vehicle engine oil, transmission oil, 

and coolant should always be checked before starting out. Finding a potential problem while in 

your driveway is better than discovering it miles from home.

6. TOWING TIPS 

If you have never towed a trailer before, be aware that it does take getting used to. To begin with,  

towing noticeably affects your vehicle’s performance:  

It will not accelerate as quickly — an important point to keep in mind when merging onto a 

highway.  

It will not stop as quickly. Leave more room than usual between you and the traffic ahead, and 

brake sooner when coming to a stop.  

Abrupt maneuvering can unbalance the load and reduce the handling and stability of your tow 

vehicle. Plan ahead and make lane changes and turns smoothly.


If possible, before you actually hit the open road, practice towing in a large uncrowded area such as 

a stadium or shopping center parking lot. Become especially familiar with backing up a trailer — the 

maneuver many people find most difficult. 

 

BRAKE SOONER 

The combination of your tow vehicle and trailer obviously requires a greater distance to stop. A 

good rule of thumb to remember is that  for each 10 mph of speed, allow yourself one tow vehicle 

and trailer length of distance between the front of your vehicle and the vehicle ahead.  

 

When braking, use firm but gradual pressure on the pedal rather than panic braking. Applying the 

brakes abruptly or with too much force can cause the trailer to skid or jackknife at its point of 

attachment with the vehicle. This, in turn, can throw the tow vehicle out of control. If equipped with 

an electric trailer brake controller, follow the recommended operational instructions. 

 

CORNER MORE SLOWLY 

Know your vehicle and trailer capabilities. Entering a sharp corner too quickly or abruptly can “crack 

the whip,” whereby the trailer can actually pull the tow vehicle off the road. Therefore, when 

approaching a relatively sharp corner, begin braking sooner than you would when not towing. Do 

your braking in a straight line prior to the corner, and turn smoothly into it. In addition, remember to 

make a wider turn than normal to ensure that the trailer safely clears the inside of the turn. 

 

BACK UP WITH CAUTION 

Backing up with a trailer is a difficult maneuver. Steer with one hand at the bottom of the steering 

wheel. To turn the trailer to the left, first move the steering wheel to the left. To turn the trailer to the 

right, move the wheel to the right. All movements of the wheel should be done in small increments. 

Of course, backing up should be done only at very slow speeds. For large trailers that obstruct your 

rearward vision, have someone outside the vehicle act as a “spotter” to guide you along.


PARK SMART 

A tow vehicle and trailer can be an unwieldy combination in a small area, so always try to park 

where you will have a relatively easy time maneuvering. Once parked, always block the wheels on 

both the tow vehicle and the trailer.   

 

Parking on a slope is not recommended. If, however, you must park on a slope and your vehicle is 

equipped with an automatic transmission, there are some precautions you should take:  

Have someone block the wheels once the tow vehicle and trailer are in position and being held 

by the vehicle’s brake. 

Next, apply the parking brake and only then move the gear lever into PARK. If you move the lever 

into PARK before blocking the wheels and applying the parking brake, it may be difficult to later 

shift out of PARK. Transmission damage may also occur.


PASS CAREFULLY 

As mentioned in the introduction to this section, because of the added weight of the trailer, 

acceleration capability is reduced and you will require a longer distance to pass another vehicle. Be 

certain you have sufficient time and space to pass safely. Never attempt to pass on hills or when 

going around curves. 

 

HILLS – UPGRADES 

As the incline increases, your vehicle — if equipped with an automatic transmission — is designed 

to automatically select the correct gear for the best towing comfort and performance. To maintain 

speed or avoid up and down shifts, manually shift to a lower gear as needed.  

 

The added weight of a trailer places an increased load on the engine and cooling system, so 

monitor your coolant temperature gauge and automatic transmission fluid temperature gauge (if 

equipped) carefully. At the first sign of overheating, pull to the side of the road. See IF YOUR ENGINE 

OVERHEATS later in this section for more information. 

 

HILLS – DOWNGRADES 

While going downhill, the weight of the trailer pushing on the tow vehicle may decrease overall 

stability. Therefore, to maintain adequate control, reduce your speed and shift to a lower gear. If 

your vehicle is equipped with Tow Mode, see your vehicle owner’s manual for information about the 

use of this function. 

 

Avoid long or repeated use of the brakes when descending a hill, as this reduces their effectiveness  

and could cause overheating. Shifting to a lower gear instead provides “engine braking” and 

reduces the need to brake as frequently. 

 

HIGH-ALTITUDE PERFORMANCE 

An engine will lose about 4% of its performance for every 1,000 feet above sea level that you travel. 

If you will be towing in high altitudes, it is a good idea to allow more time than usual due to the 

engine’s reduced performance. 

 

AUTOMATIC CRUISE CONTROL 

Do not use cruise control while towing a trailer. 

 

TOW MODE (IF EQUIPPED) 

Tow Mode is recommended when towing a heavy trailer or hauling a heavy load, particularly in 

stop-and-go traffic, rolling terrain, or a busy parking lot. 

 

Driving the vehicle in Tow Mode may affect fuel economy and transmission/engine driving 

characteristics. See your vehicle owner’s manual for additional information about Tow Mode.  

 

IF YOUR ENGINE OVERHEATS 

A moderate increase in engine operating temperature is normal when towing a trailer. If, however, 

the coolant temperature gauge reading is abnormally high, or if you are experiencing a significant 

loss of power, or if you hear unusual engine noises,* the engine may be overheating and you 

should immediately take the following steps: 
Pull your vehicle safely over to the side of the road, out of traffic. Apply the parking brake 

and move the gearshift lever to NEUTRAL (manual) or PARK (automatic). DO NOT STOP THE 

ENGINE. 

 

Turn off the air conditioning and, after opening all the windows, turn the heater on to 

maximum hot and the fan to its highest speed. The heater core in your vehicle is just like a 

miniature engine radiator and will provide an extra cooling surface to help reduce engine 

temperature.  

 

If the temperature does not drop or continues to increase, stop the engine immediately. 

 

*See your vehicle owner’s manual for additional indications that your vehicle may be overheating.


Being cautious of traffic, step out of the vehicle and, from a safe distance, look for steam 

underneath the engine. If you see steam or leaking coolant, stand clear to avoid being 

burned and shut off your engine immediately and allow it to cool. If there is no steam, open 

the hood. Never remove the radiator cap when the radiator is hot. If the cap is removed 

under these conditions, hot water/coolant under high pressure may spurt out, possibly 

causing serious injury.  

 

As soon as the engine has cooled to its normal operating temperature, visually inspect the 

drive belts for damage or looseness. A loose belt reduces water pump efficiency. Be careful 

to keep your hands, hair, jewelry, and clothing clear of the running drive belt and other 

moving parts when inspecting the engine and radiator. Also check to see if the cooling fan is 

running, and inspect the water pump, radiator, and radiator hoses for leaks. Keep in mind, 

too, that if your vehicle is equipped with an electric fan motor, it may start without warning 

any time the coolant temperature is high. If you find leaking coolant, a loose or missing drive 

belt, or an inoperable fan, turn off the engine immediately. 

 

If no leaks are apparent and all other components appear to be operating properly with the 

engine cooled to its normal operating temperature, check the coolant level in the reservoir 

tank with the engine running. Add coolant to the reservoir tank if needed. At this point, if 

repairs are required, go to the nearest Infiniti dealer. See the IN CASE OF EMERGENCY section 

of your vehicle owner’s manual for additional information on overheating. 

NOTE – All Infiniti vehicles have an engine protection mode which helps reduce the chance of 

engine damage if the engine coolant reaches a specified temperature. See your vehicle owner’s 

manual for details.

1. INTRODUCTION

SAFETY IS PRIORITY ONE 

Obviously, your first concern should be safety. Your vehicle was designed to be used primarily to 

carry passengers and cargo. Always remember that towing a trailer places additional loads on your 

vehicle’s engine, drivetrain, suspension, steering, braking, and other systems. Therefore, be certain 

that your vehicle can meet the demands of the towing application you have in mind. 

 

Rent or purchase only the highest-quality towing and safety equipment you can find. Reinforced tow 

hitches designed especially for certain Infiniti vehicles are available from your Infiniti dealer. 

Hitches for other Infiniti models — if applicable — should be bought from and installed by a 

professional supplier of towing equipment.  

 

Finally, it is important to follow the towing capacity limit set for your specific vehicle and to ensure 

that your vehicle is in top mechanical condition, especially the tires, brakes, suspension, and 

engine cooling system. See your vehicle owner’s manual for details. 

 

NEVER EXCEED THE ESTABLISHED TOWING CAPACITY 

Towing capacities vary from vehicle to vehicle. See the SPECIFICATIONS section of this guide for the 

towing capacities of 2010 Infiniti vehicles produced at the time of Towing Guide publication. Use 

this data to help select the proper Infiniti vehicle to meet your anticipated towing needs, and refer 

to it when renting a trailer or other piece of towing equipment.  

 

EQUIP YOUR INFINITI FOR TOWING 

The frequency and type of towing should influence the manner in which you equip your vehicle. If 

you plan to tow often, either for recreation or work, select the engine size, transmission type, 

suspension, and towing capacity that are best suited to your requirements. This guide can help you 

select that equipment.  

 

If, on the other hand, your towing will be infrequent, choose the Infiniti vehicle and equipment that 

best meets your day-to-day needs. Be careful not to exceed the towing capacity on those few 

occasions when you do tow.   

 

READ THIS GUIDE BEFORE YOU TOW 

This guide was designed to provide an overview of safe towing practices. Here, you will find 

information on towing equipment, safety, proper loading and driving techniques, towing tips, and 

much more. 

 

It is also a good idea to discuss your towing requirements with either your Infiniti dealer or a 

professional supplier of towing equipment before you equip your Infiniti vehicle for towing.

Finally, there are state and local laws on towing that you should review to ensure compliance with 

all regulations.

2. TOWING EQUIPMENT

RENTING 

The first thing to keep in mind when renting a trailer is to rent only from professional companies 

that specialize in towing and towing equipment. More than likely, specialized companies hire 

professional staff that can assist you in selecting and installing the proper towing equipment for 

your Infiniti vehicle. 

 

When renting, make sure you have your vehicle owner’s manual on hand so that you can reference 

the towing capacities for your specific vehicle. Never rent a trailer that exceeds these capacities, 

and make sure that any related towing equipment you rent will be sufficient for the loaded trailer. 

 

While you are there, ask questions. How much does the empty trailer weigh? How much weight will 

the trailer hold? What is the trailer’s tongue load? With what type of brakes is it equipped (if any)? 

All of these factors have an effect on whether your Infiniti vehicle is capable of safely pulling that 

type of trailer or piece of equipment. 

 

Make certain that the trailer stoplights, taillights, turn signals, and brakes (if equipped) are 

connected and are operating correctly, and that all safety equipments are properly installed. Check 

the safety chains/cables, tie-downs, etc.  

 

For safer operation, carefully inspect the condition of the trailer and towing equipment. Specifically, 

check to make sure the tires are not worn excessively and are properly inflated. Make sure there are 

not any broken welds, missing bolts, and that the hitch components are not damaged.   

 

Towing safety should be a high priority when choosing and renting towing equipment, including 

hitches.NEVER RENT A CLAMP-ON-TYPE HITCH. Your vehicle’s bumpers are not designed for using 

this type of hitch. Using it will damage your vehicle and could even result in the trailer separating 

from the towing vehicle; this can cause death or serious injury. To avoid this, use only a permanent- 

type hitch.  

 

PURCHASING 

If you are buying a travel or boat trailer, be sure that your Infiniti vehicle has the towing capacity to 

pull it. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual for 

detailed information regarding the towing capacity of your specific vehicle. Your vehicle owner’s  

manual should ALWAYS be referenced before making any towing decisions.  

 

Naturally, you will want to buy the highest-quality equipment you can find for maximum towing 

safety. And if you plan to tow often, consider convenience. Quick-disconnect trailer light connectors 

and ratchet-type tie-downs, for example, make the job go faster and easier and are usually worth 

the extra small investment. Purchase towing items such as hitches and hitch balls only from your 

Infiniti dealer or a professional supplier of towing equipment. 

 

If you are intending to use your vehicle to tow a trailer you already own, you must ensure that your 

loaded trailer remains well within your vehicle's towing capacity as specified in the vehicle owner's 

manual. In addition, you should purchase the right type, style, and class* of hitch and towing 

equipment to properly adapt the trailer to your vehicle.

3. WHAT IS RIGHT FOR YOU 

 

TYPES OF EQUIPMENT 

Towing requires a variety of equipment, and, depending upon the application, there can be several 

types or styles of each piece of equipment. Working with your Infiniti dealer or a professional 

supplier of towing equipment, it should be relatively simple to determine the proper type of 

equipment for your specific vehicle given the intended application. This section explains the most 

common pieces of towing equipment available.  

 

HITCHES 

Whichever type of hitch you use, it should be firmly bolted to your vehicle, and should be of the 

appropriate weight class for the equipment you intend to tow. In addition, keep the following in 

mind: 

 
Do not modify the vehicle’s braking or exhaust systems or its body structure/frame when 

installing the hitch.  

Installing an aftermarket hitch may affect the rear crash performance of your  vehicle.  

Be sure that the hitch does not interfere in any way with the vehicle’s impact-absorbing bumper.  

Regularly check to see that all hitch-mounting bolts are securely fastened.  

For receiver-type hitches using a ball mount, the ball mount should be removed when not 

towing. 

If you install a hitch yourself, remember that it must be securely attached to the frame or 

underbody, according to the manufacturer’s instructions. Never attach a hitch or towing device 

to the vehicle axle housing. This may damage the housing, wheel bearings, wheels, or tires.  

 

*See the SPECIFICATIONS section of this guide for equipment class information specific to your vehicle.


Hitch Types 

Bumper Hitch – This is a special reinforced bumper designed to accommodate a hitch ball.  

 

Receiver Hitch – A receiver hitch is bolted directly  to the vehicle structure for added strength and durability. Infiniti bolt-on receiver hitches are designed specifically for Infiniti vehicles and include the necessary reinforcements, with ample clearance around bumpers, frame members, etc. These hitches allow for the removal of the ball mount when not towing.


Clamp-On Bumper Hitch – This is a temporary hitch that clamps onto the bumper assembly. DO NOT USE this type of hitch on any Infiniti vehicle because using it may result in the trailer separating from the towing vehicle; this can cause death or serious injury. Use of this type of hitch can also damage the towing vehicle. 

 

Weight-Distributing Hitch System – This type of system uses a “load-leveling” or “equalizing” hitch. The weight- distributing feature helps shift the trailer tongue weight to all trailer tires and the tow vehicle front tires.   

 

For QX56 vehicles, a weight-distributing hitch ball mount (Class IV) is recommened if you plan to tow trailers with a maximum weight over 5,000 lbs. This ball mount includes a 2 5/16” hitch ball rated for up to 10,000 lbs., and is available through your Infiniti dealer. NOTE – A weight-distributing hitch system may affect the operation of trailer surge brakes. If you are considering use of a weight-distributing hitch system with a surge brake-equipped trailer, check with the surge brake, hitch, or trailer manufacturer to determine if and how this can be done. Follow the instructions provided by the manufacturer for installing and using the weight-distributing hitch system.


BALL MOUNT  

A ball mount (also known as a drawbar) is a bar that holds a hitch ball and is inserted into a 

receiver-type hitch. Ball mounts come in a number of weight capacities (3,500 lbs., 5,000 lbs., etc.) 

and sizes (1 1/4”, 2”, etc.), and can be weight-distributing or non-weight-distributing.   

 

HITCH BALL 

A hitch ball is bolted through a ball mount or a hitch hole 

in the tow vehicle’s rear bumper. The coupler on the 

trailer tongue attaches over the hitch ball. 

 

Like ball mounts, hitch balls are available in a number of 

weight capacities and sizes. Always make sure the hitch 

ball selected has the proper shank diameter and weight 

rating for the ball mount as well as the coupler on your 

trailer. Using a 1 7/8” hitch ball in a 2” coupler, for example, could result in the trailer separating 

from the tow vehicle.  

 

The diameter of the hitch ball shank must be matched to the ball mount hole diameter. The shank 

should be no more than 1/16” smaller than the hole. 

 

To keep the hitch ball in top condition, a simple maintenance routine is recommended.  Coating it 

with light grease will minimize wear of both the coupler and hitch ball. Also, by removing the hitch 

ball when not towing, or by protecting it with a special cover, you will help prevent rust from forming 

on it.

TRAILER TONGUE 

The tongue is the part of the trailer that extends forward to meet the tow vehicle, and it also carries 

the coupler assembly. Knowledge of the trailer tongue load is critical as it can have a significant 

effect on the handling of the tow vehicle. See the SPECIFICATIONS section of this guide or refer to 

your vehicle owner’s manual to view the maximum trailer tongue load listed for your vehicle.  

 

SAFETY CHAINS/CABLES 

Always use suitable safety chains/cables between the tow vehicle and the trailer. If the hitch 

should break or become disengaged for some reason, these chains/cables will provide an 

emergency connection between the vehicle and the trailer. 

 

The chains/cables should be crossed under the 

trailer tongue and attached to the hitch or 

vehicle frame. Crossing the chains/cables under 

the tongue will help prevent the tongue from 

hitting the ground should the trailer become 

disconnected.  

 

Be sure to leave enough slack in the 

chains/cables to turn corners without binding; 

however, note that excessive slack will allow the 

chains/cables to drag on the ground.  

 

Do not use S-hooks for attaching, as they may 

become un-hooked and are illegal in many 

states.  

 

To avoid damage to the bumper and chains/cables when making a sharp turn, do not attach the 

chains/cables too close to the coupler.  Consult your trailer manufacturer for the proper location of 

the chain/cable attachment to the trailer. 

 

REAR VIEW MIRRORS 

In many cases, a trailer can block your rear vision when you are using only the standard Infiniti rear 

view mirrors. These mirrors were not designed for towing. “Extended” mirrors specifically designed 

for trailer towing should be used when your rearward vision is obstructed. Before using these 

mirrors, make certain that they comply with state and local regulations. Telescoping Tow Mirrors are 

available as an accessory for QX56 vehicles. Contact your Infiniti dealer for details. 

 

SWAY CONTROL DEVICE 

Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.  

Sway control devices may be used to help control these effects. If you choose to use one, contact a 

reputable trailer hitch supplier to make sure the sway control device will work with the vehicle, 

hitch, trailer and the trailer’s brake system. Follow the instructions provided by the manufacturer for 

installing and using the sway control device. 

 

BREAKAWAY SWITCH 

On a trailer with electric brakes, a breakaway switch can automatically activate the trailer brake 

system if the trailer becomes separated from the tow vehicle. Should the trailer become detached, 

a breakaway switch may help prevent the trailer from wandering into another lane.  

 

A breakaway switch relies on the power of a trailer battery, so make sure it is not discharged. Never 

use the breakaway switch to “park” the trailer on a grade. The battery would eventually discharge 

and release the brake, allowing the trailer to roll. 

 

Be sure to leave enough slack in the tether on the breakaway switch to turn corners without 

binding.  If you do not, the electric trailer brakes will lock-up and not release. See your trailer 

manufacturer for proper installation of a breakaway switch that is compatible with your trailer 

braking system. 

 

TRAILER LIGHTS 

Trailer lights should comply with all applicable federal, state, and local regulations, and should be 

in proper working order at all times. A trailer’s taillights, stoplights, and turn signal lights must be 

wired into the towing vehicle’s electrical system.* 

 

Most trailers operate on a four-wire system in which the stoplights and turn signal lights utilize the 

same wire. All Infiniti vehicles have separate wires for the stoplights and turn signal lights, 

therefore a device called a “converter” is needed.** Specifically, a “powered converter” must be 

used, as a converter of this type creates only minimal additional electrical demand (draw) on the 

vehicle lighting circuits, which helps to ensure protection for the vehicle’s sensitive electronics. 

 

Always check for correct operation of the taillights, stoplights, and turn signal lights every time you 

connect a trailer for towing. Never replace vehicle fuses with fuses of a higher amperage rating than 

the original. 

 

*Vehicles equipped with LED taillights require that wiring be connected at a specific location. For assistance in  

  hooking up trailer lights, contact your Infiniti dealer or a professional supplier of towing equipment. 

**QX56 vehicles are pre-wired for trailer lighting and do not require a converter.

NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 

Use only an Infiniti approved wiring harness, or consult your dealer or a professional supplier of 

towing equipment for compatible equipment.  

 

BRAKES 

As with hitches, several types of braking systems are available. Most states require a separate 

braking system on trailers with a loaded weight above a specific amount, therefore you should 

check to ensure you comply with all regulations. Have a professional supplier of towing equipment 

demonstrate proper brake function testing. 

NOTE – Never connect a hydraulic trailer brake system directly to the vehicle hydraulic brake 

system.  

 

Surge Brakes – The surge brake actuator is mounted on the trailer tongue with a hydraulic line 

running to each trailer wheel. Surge brakes are activated by the trailer pushing against the hitch 

ball when the tow vehicle is braking. Hydraulic surge brakes are common on rental trailers and 

some boat trailers. In this type of system, there is no hydraulic or electric connection for brake 

operation between the tow vehicle and the trailer. 

 

Electric Trailer Brakes – Electric braking systems are activated by an electronic signal sent from a 

trailer brake controller (special brake-sensing module).  

 

If electric trailer brakes are used, Infiniti recommends all-electronic actuation because with this 

system it will not be necessary to tap into the tow vehicle’s hydraulic system.  

 

For your convenience, QX56 vehicles are pre-wired to accommodate most popular electric trailer 

brake controllers. A wiring harness* is either included with your vehicle or available from your 

Infiniti dealer.  This harness provides electric trailer brake controller input and output connections 

to the vehicle wiring. See a professional supplier of towing equipment for trailer brake controller 

availability.  

NOTE – Improper or poor quality trailer harness wiring may affect your vehicle’s electrical system. 

Use only an Infiniti approved wiring harness, or consult your dealer or professional supplier of 

towing equipment for compatible equipment.  

 

GENUINE INFINITI PARTS AND ACCESSORIES 

Whether you will be towing occasionally or on a regular basis, Infiniti offers a full range of Genuine 

Infiniti Parts and Accessories to help you tow with confidence.

certain that every item is designed to be compatible with the standard features of your vehicle and 

 

*See the SPECIFICATIONS section of this guide for wiring harness information specific to your vehicle. 

designed to assist you with your towing needs.  

 

Contact your Infiniti dealer for more information on accessories or towing-related parts for your 

Infiniti vehicle.

4. PREPARING YOUR VEHICLE  

BREAK-IN AND MAINTENANCE SCHEDULE 

Infiniti recommends that you allow a sufficient “break-in” (500 miles) of both the engine and drivetrain before towing with your new Infiniti vehicle. In addition, for the first 500 miles that you tow a trailer, do not drive over 50 mph and do not make starts at full throttle.  

 

Keep in mind, too, that towing places higher demands and added loads on vehicle components, so more frequent maintenance is called for. Your Infiniti Service & Maintenance Guide provides the accelerated maintenance schedule for towing purposes. Engine oil, filter, transmission oil, and possibly other fluids should be changed more frequently when towing. 

 

TIRE PRESSURE 

When towing a trailer, increase the tow vehicle tire pressures to the recommended cold specifications. You will find these figures in the vehicle owner’s manual and on the tire pressure chart located within the vehicle. Trailer tire condition, size, load rating, and inflation pressure must be in accordance with the trailer and tire manufacturer’s specifications. 

 

MEASURING VEHICLE WEIGHT 

The key to safe, efficient towing has to do with weight. Your vehicle — SUV, crossover, or passenger car — is capable of carrying and towing only a certain amount of weight. You must compare your vehicle’s tow weight ratings with the combined weight of the vehicle, trailer, and their contents. This will help ensure that the total weight does not exceed any of your vehicle’s tow weight ratings. There are four weights to consider when towing:  

Gross Vehicle Weight 

Gross Axle Weight (Front and Rear) 

Gross Combined Weight 

Trailer Tongue Load


These ratings are based upon normal highway driving and may be reduced if operating in reduced- traction situations, for example, slippery boat ramps. 

 

NOTE – Attempting to tow loads greater than the GVWR, GAWR, GCWR, and the trailer tongue load specified could adversely affect vehicle handling, braking, and performance. Damage to your vehicle resulting from overloading may not be covered by your vehicle warranty. 

 

GROSS VEHICLE WEIGHT (GVW) 

The Gross Vehicle Weight (GVW) is the total weight of the vehicle, plus passengers, cargo, fuel, hitch, trailer tongue weight, and any optional equipment.  

 

The best way to determine the GVW is by having the vehicle — loaded and ready to tow — weighed at a public scale. To that figure, add the combined weight of all passengers. Then, add the trailer tongue weight to determine the approximate GVW.  

 

The GVW you come up with must not exceed the Gross Vehicle Weight Rating (GVWR) for your vehicle. On all Infiniti vehicles, the GVWR is shown on the Federal Motor Vehicle Safety Standard (F.M.V.S.S.) certification label located in the driver’s-side door area.  

 

To avoid overloading the vehicle, be sure to include the trailer tongue weight as a part of the cargo when determining how much weight can be safely carried inside the vehicle. The weight of the roof rack cargo should also be included. 

 

GROSS AXLE WEIGHT (GAW) 

The Gross Axle Weight (GAW) is the maximum weight each axle (front and rear) is designed to safely carry.  

 

To determine the GAW, load the vehicle as you would for towing and attach the loaded trailer. At a public scale, with the loaded trailer attached, place only the tow vehicle front wheels on the scale to determine the actual front axle GAW. To obtain the rear axle GAW, place all four tow vehicle wheels on the scale. From that figure, subtract the front GAW and you will have the rear GAW amount.  

 

The GAW you come up with must not exceed the Gross Axle Weight Rating (GAWR) for your vehicle. On Infiniti vehicles, the GAWR for both axles is listed on the F.M.V.S.S. certification label.  

 

GROSS COMBINED WEIGHT (GCW) 

The Gross Combined Weight (GCW) is the total weight of the tow vehicle with all passengers, cargo, and fuel, plus the total weight of the trailer and all its cargo.  

 

To determine the GCW, simply weigh your vehicle when fully loaded and ready to tow, and add in the weight of the loaded trailer.  

 

The GCW you come up with must not exceed the Gross Combined Weight Rating (GCWR) for your vehicle. See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to view the GCWR listed for your vehicle.   

 

TRAILER TONGUE LOAD 

Trailer tongue load is the amount of weight pressing down on the tow vehicle hitch.  

 

To measure trailer tongue load, place the tongue of the trailer on a scale when the trailer is not attached to the vehicle. A separate vehicle jack — not the trailer jack — should be used, as the location of the trailer jack is rearward of the trailer tongue and will not give you an accurate measurement of the true tongue load. Make sure the vehicle jack is placed directly under the trailer tongue coupler, and the tongue is set at the height/level of the tow vehicle hitch.  

 

For proper handling, you must keep the trailer tongue load between 10-15% of the actual trailer weight, within the limits of the maximum trailer tongue load allowable. For example, to determine the proper trailer tongue load for a 1,500-lb. trailer, multiply the weight of 1,500 lbs. by 10% to arrive at a figure of 150 lbs.  

 

Some trailer types may require different trailer tongue loads for safe towing. Always follow the trailer manufacturer’s recommendations for proper trailer set-up and trailer tongue load. Keep the trailer tongue load within the maximum trailer tongue load allowable. Additionally, make sure the vehicle has the payload capacity available for the trailer tongue load.  

 

See the SPECIFICATIONS section of this guide or refer to your vehicle owner’s manual to view the maximum trailer tongue load listed for your vehicle.  

NOTE – The vehicle weight ratings (GVWR, GAWR, GCWR, etc.) must not be exceeded, regardless of trailer or hitch type. 

 

HITCH & TRAILER HEIGHT 

It is important that your trailer floor and tongue ride as level as possible. This  will help prevent over-angling, bottoming-out, and improper load transfer. Therefore, the hitch or trailer tongue must be adjusted during the initial vehicle/trailer fit-up to ensure a level ride. Ball mounts are available in different configurations to adjust the hitch ball height.


5. TOWING SAFETY 

Towing can significantly alter the handling and performance characteristics of your vehicle. Plus, it 

puts increased strain on the engine and drivetrain. Therefore, it is always a good idea to approach 

towing from the standpoint of safety — whether you are purchasing equipment or actually pulling 

the trailer.  

 

Always make sure your vehicle’s towing capacity is adequate for the trailer you intend to tow. Buy or 

lease only quality equipment. In addition, be certain that you have all of the equipment needed for 

safe towing, such as safety chains/cables, electric trailer brakes, electric trailer brake controller, 

breakaway switch, and extended rear view mirrors.  

 

You should follow a more frequent maintenance schedule and check fluid levels, pressures, tire 

condition, etc., more often when on the road. See your vehicle owner’s manual for details. 

 

LOADING YOUR TRAILER 

Taking the time to load and balance your trailer properly will improve overall handling and minimize 

the strain on your tow vehicle. Incorrectly loaded trailers tend to sway or swing from side to side, 

upsetting vehicle handling. Careful loading and balancing can help eliminate these problems. 

 

As mentioned earlier, trailer tongue load must fall between 10-15% of the total trailer weight, or 

within the limits of the maximum trailer tongue load specified by the trailer manufacturer. Excessive 

trailer tongue load can actually push down the vehicle in back, lifting the front wheels to a point 

where traction, steering response, and braking are severely reduced. Insufficient trailer tongue load 

can cause instability, which may lead to “tail wagging” or jackknifing. 

 

With this in mind, proper loading is extremely important. When loading a trailer, 60% of the total 

cargo weight should be positioned in the front portion of the trailer and 40% in the back. Then the 

load should be adjusted until the proper tongue load ratio is achieved.  

 

The trailer load should be balanced equally from side-to-side. Unequal side-to-side loading can 

negatively affect handling and braking. Once in place, all cargo should be firmly secured to prevent 

shifting. If the load should shift abruptly during braking or cornering, it could quickly affect the 

handling of your vehicle and cause a very unsafe situation.  

 

Finally, do not carry flammable materials, such as gasoline, in your trailer. In the event of an 

accident, an explosion or fire could occur. 

 

ENSURING VEHICLE/TRAILER STABILITY 

Improper loading, excessive or insufficient trailer tongue load, overloading, excessive trailer 

weight, poorly designed trailer suspensions, crosswinds, and poor maintenance are all things that 

can affect the stability of your vehicle and trailer combination. 

 

If swaying does occur, check the cargo load for proper balance and distribution to ensure proper 

trailer tongue load. In addition, check the condition of the suspension and shocks, as well as the 

tires, tire pressures, and wheel bearings on both the tow vehicle and trailer.  

 

If the swaying continues and your trailer is suitably balanced and within the towing capacity limits 

of your vehicle, discontinue towing and consult your Infiniti dealer or trailer manufacturer to 

determine the problem.  

 

VEHICLE SPEED 

Please note that some states have specific regulations and speed limits for vehicles that are towing 

trailers. Remember to reduce your speed in unsafe or less-than-ideal road conditions or weather. 

When towing a trailer, braking distances increase while handling agility decreases. Always leave 

yourself an extra margin of distance to respond to emergency situations. 

 

PASSENGERS 

Never allow passengers to ride inside a trailer while it is being towed. Not only is this unlawful in 

most areas, passengers could be seriously injured during sudden trailer movement or in an 

accident. In addition, trailers may allow fumes from the tow vehicle to leak inside. This could result 

in carbon monoxide poisoning from the engine exhaust. 

 

VEHICLE MODIFICATIONS 

Vehicle modifications — beyond those required for proper hitch installation, wiring hook-up, and 

necessary cooling system upgrading — are not recommended for any Infiniti vehicle being used for 

towing purposes. Changes to the drivetrain, suspension, exhaust systems, frame 

structure/unibody, or other vehicle components are not necessary for towing within the limits 

described in this guide. These changes may diminish the reliability and longevity of your vehicle 

and possibly void warranty coverage. 

 

TOOL KIT 

When towing, bring tools including flares, a flashlight, emergency reflectors, jumper cables, extra 

fuses, extra radiator coolant, oil, and easily replaced spare parts such as taillight bulbs. You should 

also carry spare tires for your tow vehicle and trailer, as well as a jack suitable for use on the trailer. 

Be aware that not all automotive jacks can be used safely on a trailer. 

 

BEFORE STARTING OUT 

Before starting out on a trip, make one last inspection of the tow vehicle and the trailer. Are the tire 

pressures correct? Are the safety chains/cables securely in place? Is the cargo tied down securely? 

Do all the lights work? Is the coupler properly attached over the hitch ball and secured using a 

locking pin? Is the breakaway switch hooked up and functioning properly? Are vehicle and electric 

trailer brakes working properly?  

 

Make a checklist of key items to be inspected. When towing, vehicle engine oil, transmission oil, 

and coolant should always be checked before starting out. Finding a potential problem while in 

your driveway is better than discovering it miles from home.

6. TOWING TIPS 

If you have never towed a trailer before, be aware that it does take getting used to. To begin with,  

towing noticeably affects your vehicle’s performance:  

It will not accelerate as quickly — an important point to keep in mind when merging onto a 

highway.  

It will not stop as quickly. Leave more room than usual between you and the traffic ahead, and 

brake sooner when coming to a stop.  

Abrupt maneuvering can unbalance the load and reduce the handling and stability of your tow 

vehicle. Plan ahead and make lane changes and turns smoothly.


If possible, before you actually hit the open road, practice towing in a large uncrowded area such as 

a stadium or shopping center parking lot. Become especially familiar with backing up a trailer — the 

maneuver many people find most difficult. 

 

BRAKE SOONER 

The combination of your tow vehicle and trailer obviously requires a greater distance to stop. A 

good rule of thumb to remember is that  for each 10 mph of speed, allow yourself one tow vehicle 

and trailer length of distance between the front of your vehicle and the vehicle ahead.  

 

When braking, use firm but gradual pressure on the pedal rather than panic braking. Applying the 

brakes abruptly or with too much force can cause the trailer to skid or jackknife at its point of 

attachment with the vehicle. This, in turn, can throw the tow vehicle out of control. If equipped with 

an electric trailer brake controller, follow the recommended operational instructions. 

 

CORNER MORE SLOWLY 

Know your vehicle and trailer capabilities. Entering a sharp corner too quickly or abruptly can “crack 

the whip,” whereby the trailer can actually pull the tow vehicle off the road. Therefore, when 

approaching a relatively sharp corner, begin braking sooner than you would when not towing. Do 

your braking in a straight line prior to the corner, and turn smoothly into it. In addition, remember to 

make a wider turn than normal to ensure that the trailer safely clears the inside of the turn. 

 

BACK UP WITH CAUTION 

Backing up with a trailer is a difficult maneuver. Steer with one hand at the bottom of the steering 

wheel. To turn the trailer to the left, first move the steering wheel to the left. To turn the trailer to the 

right, move the wheel to the right. All movements of the wheel should be done in small increments. 

Of course, backing up should be done only at very slow speeds. For large trailers that obstruct your 

rearward vision, have someone outside the vehicle act as a “spotter” to guide you along.


PARK SMART 

A tow vehicle and trailer can be an unwieldy combination in a small area, so always try to park 

where you will have a relatively easy time maneuvering. Once parked, always block the wheels on 

both the tow vehicle and the trailer.   

 

Parking on a slope is not recommended. If, however, you must park on a slope and your vehicle is 

equipped with an automatic transmission, there are some precautions you should take:  

Have someone block the wheels once the tow vehicle and trailer are in position and being held 

by the vehicle’s brake. 

Next, apply the parking brake and only then move the gear lever into PARK. If you move the lever 

into PARK before blocking the wheels and applying the parking brake, it may be difficult to later 

shift out of PARK. Transmission damage may also occur.


PASS CAREFULLY 

As mentioned in the introduction to this section, because of the added weight of the trailer, 

acceleration capability is reduced and you will require a longer distance to pass another vehicle. Be 

certain you have sufficient time and space to pass safely. Never attempt to pass on hills or when 

going around curves. 

 

HILLS – UPGRADES 

As the incline increases, your vehicle — if equipped with an automatic transmission — is designed 

to automatically select the correct gear for the best towing comfort and performance. To maintain 

speed or avoid up and down shifts, manually shift to a lower gear as needed.  

 

The added weight of a trailer places an increased load on the engine and cooling system, so 

monitor your coolant temperature gauge and automatic transmission fluid temperature gauge (if 

equipped) carefully. At the first sign of overheating, pull to the side of the road. See IF YOUR ENGINE 

OVERHEATS later in this section for more information. 

 

HILLS – DOWNGRADES 

While going downhill, the weight of the trailer pushing on the tow vehicle may decrease overall 

stability. Therefore, to maintain adequate control, reduce your speed and shift to a lower gear. If 

your vehicle is equipped with Tow Mode, see your vehicle owner’s manual for information about the 

use of this function. 

 

Avoid long or repeated use of the brakes when descending a hill, as this reduces their effectiveness  

and could cause overheating. Shifting to a lower gear instead provides “engine braking” and 

reduces the need to brake as frequently. 

 

HIGH-ALTITUDE PERFORMANCE 

An engine will lose about 4% of its performance for every 1,000 feet above sea level that you travel. 

If you will be towing in high altitudes, it is a good idea to allow more time than usual due to the 

engine’s reduced performance. 

 

AUTOMATIC CRUISE CONTROL 

Do not use cruise control while towing a trailer. 

 

TOW MODE (IF EQUIPPED) 

Tow Mode is recommended when towing a heavy trailer or hauling a heavy load, particularly in 

stop-and-go traffic, rolling terrain, or a busy parking lot. 

 

Driving the vehicle in Tow Mode may affect fuel economy and transmission/engine driving 

characteristics. See your vehicle owner’s manual for additional information about Tow Mode.  

 

IF YOUR ENGINE OVERHEATS 

A moderate increase in engine operating temperature is normal when towing a trailer. If, however, 

the coolant temperature gauge reading is abnormally high, or if you are experiencing a significant 

loss of power, or if you hear unusual engine noises,* the engine may be overheating and you 

should immediately take the following steps: 
Pull your vehicle safely over to the side of the road, out of traffic. Apply the parking brake 

and move the gearshift lever to NEUTRAL (manual) or PARK (automatic). DO NOT STOP THE 

ENGINE. 

 

Turn off the air conditioning and, after opening all the windows, turn the heater on to 

maximum hot and the fan to its highest speed. The heater core in your vehicle is just like a 

miniature engine radiator and will provide an extra cooling surface to help reduce engine 

temperature.  

 

If the temperature does not drop or continues to increase, stop the engine immediately. 

 

*See your vehicle owner’s manual for additional indications that your vehicle may be overheating.


Being cautious of traffic, step out of the vehicle and, from a safe distance, look for steam 

underneath the engine. If you see steam or leaking coolant, stand clear to avoid being 

burned and shut off your engine immediately and allow it to cool. If there is no steam, open 

the hood. Never remove the radiator cap when the radiator is hot. If the cap is removed 

under these conditions, hot water/coolant under high pressure may spurt out, possibly 

causing serious injury.  

 

As soon as the engine has cooled to its normal operating temperature, visually inspect the 

drive belts for damage or looseness. A loose belt reduces water pump efficiency. Be careful 

to keep your hands, hair, jewelry, and clothing clear of the running drive belt and other 

moving parts when inspecting the engine and radiator. Also check to see if the cooling fan is 

running, and inspect the water pump, radiator, and radiator hoses for leaks. Keep in mind, 

too, that if your vehicle is equipped with an electric fan motor, it may start without warning 

any time the coolant temperature is high. If you find leaking coolant, a loose or missing drive 

belt, or an inoperable fan, turn off the engine immediately. 

 

If no leaks are apparent and all other components appear to be operating properly with the 

engine cooled to its normal operating temperature, check the coolant level in the reservoir 

tank with the engine running. Add coolant to the reservoir tank if needed. At this point, if 

repairs are required, go to the nearest Infiniti dealer. See the IN CASE OF EMERGENCY section 

of your vehicle owner’s manual for additional information on overheating. 

NOTE – All Infiniti vehicles have an engine protection mode which helps reduce the chance of 

engine damage if the engine coolant reaches a specified temperature. See your vehicle owner’s 

manual for details.


7. TOWING GLOSSARY

BALL MOUNT

A bar that holds the hitch ball and is inserted into the hitch receiver. Also commonly called a drawbar.


BREAKAWAY SWITCH 

A safety device using a trailer battery that automatically applies the trailer’s brakes if it should accidentally become separated from the tow vehicle. A breakaway switch may be used with both electric or surge trailer brake systems.


BUMPER HITCH 

A reinforced bumper designed to accommodate a hitch ball.


ELECTRIC TRAILER BRAKES

When the brakes on a tow vehicle are applied, an electric current is sent to an actuator which applies the trailer’s brakes.


ELECTRIC TRAILER BRAKE CONTROLLER

A device that controls the electric trailer brakes.


GROSS AXLE WEIGHT RATING (GAWR)

The maximum amount of weight each vehicle axle (front and rear) is designed to safely carry.


GROSS COMBINED WEIGHT RATING (GCWR) 

The maximum allowable combined weight of the vehicle and trailer, including passengers and all cargo.


GROSS VEHICLE WEIGHT RATING (GVWR)

The maximum allowable weight of the vehicle, including passengers, cargo, fuel, hitch, trailer tongue load, and any optional equipment.


HITCH BALL

A ball that connects the trailer to the tow vehicle hitch and provides the means by which the trailer pivots during cornering.  Available in a number of sizes and weight capacities, it must correspond to the trailer coupler size, and have a sufficient capacity rating for the trailer being pulled.


RECEIVER HITCH

A frame- or structure-mounted hitch with a receiver that allows removal of the ball mount.


SAFETY CHAINS/CABLES

Provides an emergency connection between the tow vehicle and the trailer, should the trailer become disengaged for any reason.


SURGE BRAKES

Hydraulic-type braking system activated by inertia. As the tow vehicle begins to brake, the trailer pushes against the hitch ball, consequently activating the trailer brakes.


TRAILER TONGUE/COUPLER

The part of the trailer that extends forward to meet the tow vehicle, and also carries the coupler assembly.


TRAILER TONGUE LOAD

The amount of trailer weight pressing down on the hitch.


WEIGHT-DISTRIBUTING HITCH SYSTEM
