Driving 4x4 w/manual transmission GCWR (Gross Combined Weight Rating)/Trailer Weights Trailer Weight Maximum Rear Maximum Range frontal area of Engine axle GCWR - kg (0-Maximum) trailer - m2 ratio (lbs.) (ft2) - kg (lbs.) 4.0L 0-1134 All 3175 (7000) 4.64 (50) SOHC (0-2500) Notes: For high altitude operation, reduce GCW by 2% per 300 meters (1000 ft) elevation. For definition of terms and instructions on calculating your vehicle's 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. Do not exceed the GVWR or the GAWR specified on the certification label. Towing trailers beyond the maximum recommended gross trailer weight exceeds the limit of the vehicle and could result in engine damage, transmission damage, structural damage, loss of vehicle control, vehicle rollover and personal injury. 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% of the total weight of the trailer is on the tongue. Use a frame-mounted weight distributing hitch for trailers over 1588 kg (3500 lb). Safety chains Always connect the trailer's safety chains to the frame or hook retainers of the vehicle hitch. To connect the trailer's safety chains, cross the chains under the trailer tongue and allow slack for turning corners. Do not attach safety chains to the bumper. 121
