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 s ome reason, these chain s/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 cro ssed under the trailer tongue and attached to the hitch or
vehicle frame. Crossing the chain s/cables under the tongue will help prevent the tongue
from hitting the ground should the trailer become disconnected .
B e sure to leave enough slack in the chain s/ 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 mirror s 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 l ocal 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.

A sway control device is recommended for all t owing above 2,000 lb (907 kg). Too low a
percentage of tongue weight can also cause sway. Follow the instructions provided by the
manufacturer for installing and using the sway control device.

PASSENGERS

WARNING - Never allow passengers to ride inside a trailer while it is being towed.
Not only is this unlawful in m ost areas, passengers could be seriously injured during
sudden t railer 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/un ibody, 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 ca use 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 on e 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 tr ailer-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 traile r.
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 poten tial
problem while in your driveway is better than discovering it miles from home.
If you ha ve never towed a trailer before, be aware that it does take getting used to.

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 i f 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 vehicle s have an engine protection mo de which helps reduce the
chance of engine damage if the engine coolant reaches a specified temperature.

TOWING GLOSSARY


BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver.
BRE AK AWAY SWI TCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if it should accidentally become separated from the tow vehicle.
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).
