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 engine protection mode, which helps reduce the chance of 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. 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. Refer to "If your vehicle overheats" in the "In case of emergency" section of this manual. WTI0160 ATI1025 Tongue load When using a weight carrying or a weight distributing hitch, keep the tongue load between 10 15 percent 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. Maximum Gross Vehicle Weight (GVW)/maximum Gross Axle Weight (GAW) The GVW of the towing vehicle must not exceed the Gross Vehicle Weight Rating (GVWR) shown on the F.M.V.S.S./C.M.V.S.S. certification label. The GVW equals the combined weight of the unloaded vehicle, passengers, luggage, hitch, trailer tongue load and any other optional equipment. In addition, front or rear GAW must not exceed the (GAWR) shown on the F.M.V.S.S./C.M.V.S.S. certification label. CAUTION Vehicle damage resulting from improper towing procedures is not covered by NISSAN warranties. 9-20 Technical and consumer information
