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 minimum and maximum tongue load is critical as it
can have a significant effect on the handling and capacity of the tow vehicle. Refer to your vehicle
owner’s manual to view the maximum conventional trailer tongue load listed for your vehicle. Trailer
tongue weight is the amount of downward pressure exerted onto the hitch ball. Keep the tongue
load between 10-15% of the total trailer weight. DO NOT exceed the maximum tongue load
specification. If the tongue weight is below the recommended amount, you must move some of the
load forward or add weight to the front frame of the trailer.

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 ultimate combined breaking
strength of the two chains must be equal to the gross weight of the towed vehicle(s).

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.

WARNING- Do not use S-hooks for attaching the safety chains as they may become un-hooked
while towing. If the S-hook unhooks, the emergency chains/cables will become detached, so if the
tow hitch breaks or becomes disengaged, it will allow the trailer to completely break away causing
property damage and possibly personal injury or death. The use of S-hooks is illegal in many states.

CAUTION- 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

WARNING- In many cases, a trailer can block your rear vision when you are using only the
standard INFINITI rear view and outside mirrors. Be careful when changing lanes or turning. Using
only these mirrors could cause an accident as they 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 certain INFINITI vehicles.
Contact your INFINITI retailer for details.

SWAY CONTROL DEVICE
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.
Sway control devices may help control the pivoting motion between tow vehicle and trailer and
make trailer towing easier on the driver. 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.

PASSENGERS

WARNING- 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

WARNING - DO NOT modify your vehicle beyond those required for proper hitch installation,
wiring hook-up, or adding extended mirrors on any INFINITI vehicle being used for towing purposes.
Changes to the drivetrain, suspension, exhaust systems, electrical, 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, void warranty coverage or
possible result in loss of vehicle control and cause an accident, personal injury or death.


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.
Choose a jack that can raise and lower the trailer so that you can connect the coupler to and
disconnect it from the ball of your hitch. Choose one with a weight capacity that matches or
surpasses your trailer tongue weight.


WARNING- Be aware that your automotive jack is designed for lifting only your vehicle during a
tire change. Using an automobile jack to lift a trailer-bearing load may be unstable possibly causing
it to fall off the jack stand which may result in property damage or serious injury or death.

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

20 6. 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 retailer. 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.



NOTES












Passenger Vehicles – INFINITI does not recommend trailer towing with Q50, Q60, Q70, or Q70 (HEV)
vehicles.

Cross-Over Vehicles – INFINITI
does not recommend trailer towing with QX30, QX50, or the QX70 2WD
vehicles.

Other Recommendations and Information – Towing performance and speed are affected by vehicle
payload, tow weight, road grades, and weather conditions, including high temperatures. See your
vehicle owner’s manual for details.





1 Maximum Trailer Weight values are calculated assuming a base vehicle with
driver and any options required, to achieve the rating. Additional
passengers, cargo and/or optional equipment will add weight to the vehicle
and reduce your vehicle’s maximum towing capacity and trailer tongue
load.

2 In general, a weight-distributing hitch system (Class IV) should be used
when towing over 5,000 lbs.

3 Most states require a separate braking system on trailers with a loaded
weight above a specific amount. Check local ordinances. 7-pin connector
trailer wire harnesses are required for use with trailer brakes (available
separately).

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 that 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 carries
the coupler assembly.
TRAILER TONGUE
LOAD The amount of trailer weight pressing down on the hitch.
WEIGHT-DISTRIBUTING
HITCH SYSTEM Type of hitch system that helps shift the trailer tongue weight to all trailer tires
and the tow vehicle front tires. Strongly recommended when towing trailers with a
Maximum Trailer Weight greater than 5,000 lbs.
WIRING HARNESS
Provides an electrical connection linking the tow vehicle’s electrical system to the
trailer’s system.
