The 2010 Infiniti Towing Guide provides information for currently available 2010 Infiniti vehicles. This publication (as well as my post) will be amended as new vehicles are introduced.
Although mainly created to help those with Infiniti vehicles, this guide contains useful towing information and tips that will help a person with ANY type of vehicle.
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
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
2. TOWING EQUIPMENT
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-
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.
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
- 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
- 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.
- 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.
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.
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
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.
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
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
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.
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
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
*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.
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
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
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.

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.
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
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.
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.
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 — 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.
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
- 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.
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.
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.
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.
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
- 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
- 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
