PREPARING YOUR VEHICLE
BREAK-IN AND MAINTENANCE SCHEDULE
CAUTION- INFINITI recommends that you allow a sufficient “break-in” of both the
engine and drivetrain before towing with your new INFINITI vehicle.
DO NOT tow a trailer or haul a heavy load for the first 500 miles. For the first 500 miles
that you tow a trailer, do not drive over 50 mph and do not make starts at full throttle.
Following these recommendations helps your engine and other parts of your vehicle
wear in at heavier loads.

Keep in mind, too, that towing places higher demands and added loads on vehicle
components, so more frequent maintenance is called for. Your INFINITI Owner’s
Manual & 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 safer, efficient towing has to do with weight. Your vehicle — SUV, or
crossover vehicle — 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- curb weight of vehicle plus the combined weight of
passengers and cargo
 Gross Axle Weight (Front and Rear)- maximum weight (load limit)that can be
specified for front or rear axle
 Gross Combined Weight- maximum total weight of vehicle, passengers, cargo,
and trailer
 Trailer Tongue Load- the weight exerted at the vehicle-trailer coupling point

These ratings are based upon normal highway driving and may be reduced if
operating in reduced-traction situations (for example, slippery boat ramps).

WARNING- Attempting to tow loads greater than the GVWR, GAWR, GCWR, and
the trailer tongue load specified could adversely affect vehicle handling, stability,
braking, and performance. Parts of your vehicle can break, and tire damage could
occur as a result of overloading; this may not be covered by your vehicle warranty.
Overloading can also result in loss of control of your vehicle and which could cause a
serious accident, personal injury or death.

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.
