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 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. 167
