Maximum trailer loads

Never allow the total trailer load to exceed the value specified in the “Towing load/ specification” later in this section. The total trailer load equals trailer weight plus its cargo weight.

. When towing a trailer load of 3,500 lbs (1,587 kg) or more, trailers with a brake system MUST be used.

The maximum Gross Combined Weight Rating (GCWR) should not exceed the value specified in the following “Towing Load/ Specification” chart.

The GCWR equals the combined weight of

The GCWR equals the combined weight of the towing vehicle (including passengers and cargo) plus the total trailer load. Towing loads greater than these or using improper towing equipment could adversely affect vehicle handling, braking and performance. The ability of your vehicle to tow a trailer is not only related to the maximum trailer loads, but also the places you plan to tow. Tow weights appropriate for level highway driving may have to be reduced on very steep grades or for low traction situations (for example, on slippery boat ramps). Temperature conditions can also affect towing. For example, towing a heavy trailer in high outside temperatures on graded roads can affect engine performance and cause overheating. The transmission high fluid temperature and engine protection mode, which helps reduce the chance of transmission and engine damage, could activate and automatically decrease engine power. Vehicle speed may decrease under high load. Plan your trip carefully to account for trailer and vehicle load, weather and road conditions.

Overheating can result in reduced engine WARNING
Overheating can result in reduced engine power and vehicle speed. The reduced speed may be lower than other traffic, which could increase the chance of a collision. Be especially careful when driving. If the vehicle cannot maintain a safe driving speed, pull to the side of the road in a safe area. Allow the engine to cool and return to normal operation. See “If your vehicle overheats” in the “6. In case of emergency” section of this manual.

CAUTION
Vehicle damage resulting from improper towing procedures is not covered by INFINITI warranties.

Tongue load

When using a weight carrying or a weight

When using a weight carrying or a weight distributing hitch, keep the tongue load between 10 to 15% of the total trailer load or use the trailer tongue load specified by the trailer manufacturer. The tongue load must be within the maximum tongue load limits shown in the following “Towing Load/Specification” chart. If the tongue load becomes excessive, rearrange cargo to allow for proper tongue load.
