The combined weight of the completed towing vehicle and the loaded trailer must not exceed the GCWR. *-When towing maximum loads under high outside temperatures and on steep grades, the A/C system may cycle on and off to protect the engine from overheating. This may result in a temporary increase of interior temperatures. Towing a trailer over 3,500 lb. (1,588 kg) requires a weight distributing hitch. Preparing to tow Use the proper equipment for towing a trailer and make sure it is properly attached to your vehicle. See your dealer or a reliable trailer dealer if you require assistance. Hitches Do not use hitches that clamp onto the vehicle bumper. Use a load carrying hitch. You must distribute the load in your trailer so that 10-15% of the total weight of the trailer is on the tongue, not to exceed the maximum tongue loads as stated: • Class II receiver: 350 lb.
