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 retailer 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 adjustment
specifications refer to the brake controller manual for the controller being used.

For your convenience, QX56 and JX35 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 retailer. This harness provides electric trailer brake controller input and output
connections to the vehicle wiring. Contact an Infiniti retailer or a professional supplier of towing
equipment for information on trailers equipped with electric brakes and for Genuine Infiniti jumper
harness availability for your specific vehicle.
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 retailer or professional supplier of
towing equipment for compatible equipment.

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:
Š Gross Vehicle Weight
Š Gross Axle Weight (Front and Rear)
Š Gross Combined Weight
Š 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. 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.

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 tongue load and 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 and
weight distribution hitches are available in
different configurations to adjust the tongue
load and load transfer and hitch ball height.

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, conventional 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 or negative load can lift the trailer tongue upwards on the trailer ball causing 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.

TOWING SAFETY

2013 Infiniti Towing Guide

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 retailer 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.

2013 Infiniti Towing Guide

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, or
adding extended mirrors — 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 damage caused by
such modifications may not be covered under your vehicle’s warranty.

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.
