NOTE: The rated capacities (as shown in this guide) for trailer towing with the factory bumper are only valid when the trailer hitch ball is installed directly into the ball hole in the bumper. Addition of bracketry to either lower the hitch ball position or extend the hitch ball rearward will significantly increase the loads on the bumper and its attachments. This can result in the failure of the bumper or the bumper attachments. Use of any type of hitch extensions should be considered abuse. If it is necessary to relocate the trailer hitch ball position a frame mounted trailer hitch must be installed. Safety Chains Always use safety chains between your vehicle and trailer. Cross chains under the trailer tongue and allow slack for turning corners. Connect safety chains to the vehicle frame or hook retainers. Never attach chains to the bumper. Trailer Brakes Separate trailer brakes are required on most towed vehicles weighing over 1,500 lb (680 kg). RWARNING 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. 214
