For definitions of terms used in this table and instructions on how to calculate your vehicle load, refer to Vehicle loading in this chapter. Maximum trailer weights shown. 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/or 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 1588 kg (3500 lbs.) 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. 176 2003 Explorer (exp) Owners Guide (post-2002-fmt) USA English (fus)
