Driving 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. Trailer brakes Electric brakes and manual, automatic or surge-type trailer brakes are safe if installed properly and adjusted to the manufacturer's specifications. Do not connect a trailer's hydraulic brake system directly to your vehicle's brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase. The braking system of the towing vehicle is rated for operation at the GVWR not GCWR. Trailer lamps Make sure your trailer lamps conform to local and Federal regulations. See your dealer or trailer rental agency for proper instructions and equipment for hooking up trailer lamps. Never connect any trailer lighting to the vehicle's taillamp circuits, because it may damage the electrical system resulting in fire. Contact your local Ford dealership for assistance in proper trailer tow wiring installation. Additional electrical equipment may be required. Using a step bumper The rear bumper is equipped with an integral hitch and requires only a ball with a 19 mm (3/4 inch) shank diameter. The bumper has a 1,590 kg (3,500 lb.) trailer weight and 159 kg (350 lb.) tongue weight capability. Use a frame-mounted weight distributing hitch for trailers over 1,590 kg (3,500 lb). 108
