height. On some tandem axle trailers an incorrect hitch height can result in uneven
trailer axle loading.

WARNING- Towing can significantly alter the handling, stability and performance
characteristics of your vehicle. Moreover, 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.

WARNING- Always make sure your vehicle’s towing capacity is adequate for the
trailer you intend to tow. Be certain that you have all of the proper equipment needed
for safe towing, such as safety chains/cables, electric trailer brakes, electric trailer
brake controller, breakaway switch, and extended rear view mirrors. Make certain
your equipment conforms to all federal, state or local regulations to help avoid against
the possibility of a serious accident and personal injury or death.

You should follow a more frequent maintenance schedule and check fluid levels,
pressures, tire condition, etc., more often when on the road. Refer to your vehicle
owner’s manual for details. It is recommended you visit an INFINITI retailer for service.
LOADING YOUR TRAILER

WARNING- 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 and stability which
could result in a serious accident, personal injury or death. Careful loading and
balancing, and a weight distribution hitch and sway-control device 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.

WARNING- Excessive trailer tongue load can actually push down the tow vehicle in
back, lifting the front wheels to a point where traction, steering response, and braking
may be severely reduced. which could result in an accident, personal injury or death.
Too little trailer tongue load or negative load can lift the trailer tongue upwards on the
trailer ball causing instability, which may lead to swaying, “tail wagging,” or jackknifing
which could result in an accident, personal injury or death.

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.

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

WARNING- While going downhill, the weight of the trailer pushing on the tow vehicle
may decrease overall stability, and may deteriorate overall handling characteristics.
The vehicle may handle unpredictably which could cause a loss of vehicle control
resulting in an accident, property damage, serious injury or death. Therefore, to
maintain adequate control, reduce your speed and shift to a lower gear and apply
the braking in short bursts. If your vehicle is equipped with Tow Mode, see your vehicle
owner’s manual for information about the use of this function.

WARNING- Avoid long or repeated use of the brakes when descending a hill, as this
reduces their effectiveness and could cause overheating which could result in
damage to your brake components or unable to slow to a safe speed. 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.

While towing a trailer, do not use the following systems (if so equipped):
— ProPILOT Assist
— the Lane Departure Warning (LDW) system
— the Lane Departure Prevention (LDP) system
— the Blind Spot Warning (BSW) system
— the Blind Spot Intervention® (BSI) system
— the Back-up Collision Intervention (BCI) system
— the Intelligent Cruise Control (ICC) system
— the Distance Control Assist (DCA) system
— the Forward Emergency Braking (FEB) with pedestrian detection system
— the Predictive Forward Collision Warning (PFCW) system.

INTELLIGENT CRUISE CONTROL

WARNING- In order to maintain a safe distance to the vehicle ahead to avoid the
possibility of accidents, property damage, serious injury or death. INFINITI recommends
not to use the Intelligent Cruise control (ICC) system while towing a trailer or other
vehicle. In certain road conditions when your vehicle is towing, the ICC sensor may
not detect a vehicle ahead. If the ICC sensor cannot detect the reflector on the
vehicle ahead, the ICC system may not maintain the selected distance which could
cause an accident, property damage, or death.
