2-5. Driving information CAUTION n Trailer towing precautions l Follow all the instructions described in this section. Failure to do so could cause an accident resulting in death or serious injury. l Exceeding the towing capacity, GVWR or GAWR can cause an accident result- ing in death or serious personal injuries. n To avoid accident or injury l Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle weight and trailer tongue load capacities. l Never load more weight in the back than in the front of the trailer. About 60% of the load should be in the front half of the trailer, and the remaining 40% in the rear. l For vehicles with an electronically modulated air suspension, set the vehicle height to LO mode and turn off the electronically modulated air suspension to prevent the vehicle height from automatically changing. l The tow hitch receiver installed on your vehicle must never be used on another vehicle. l Do not exceed 45 mph (72 km/h) or the posted towing speed limit, whichever is lower. As instability (swaying) of the towing vehicle-trailer combination increases as speed increases, exceeding 45 mph (72 km/h) may cause loss of control. l Slow down and downshift before descending steep or long downhill grades. Do not make sudden downshifts. l Avoid holding the brake pedal down too long or applying the brakes too fre- quently. This could cause the brakes to overheat and result in reduced braking efficiency. l Do not tow the vehicle with the compact spare tire installed. 288
