Towing Trailer Towing Connector Do not use a hitch that either clamps onto the bumper or attaches to the axle. You must distribute the load in your trailer so that 10-15% for conventional towing or 15-25% for fifth wheel towing of the total weight of the trailer is on the tongue. Weight-distributing Hitches WARNING Do not adjust a weight-distributing hitch to any position where the rear bumper of the vehicle is higher than it was before attaching the trailer. Doing so will defeat the function of the weight-distributing hitch, which may cause unpredictable handling, and could result in serious personal injury. When hooking-up a trailer using a weight-distributing hitch, always use the following procedure: 1. 2. Park the loaded vehicle, without the trailer, on a level surface. Measure the height to the top of your vehicle's front wheel opening on the fender. This is H1. Attach the loaded trailer to your vehicle without the weight-distributing bars connected. Measure the height to the top of your vehicle's front wheel opening on the fender a second time. This is H2. Install and adjust the tension in the weight-distributing bars so that the height of your vehicle's front wheel opening on the fender is approximately halfway between H1 and H2. Check that the trailer is level or slightly nose down toward your vehicle. If not, adjust the ball height accordingly and repeat Steps 2-6. E163167 When attaching the trailer wiring connector to your vehicle, only use a proper fitting connector that works with the vehicle and trailer functions. Some seven-position connectors may have the SAE J2863 logo, which confirms that it is the proper wiring connector and works correctly with your vehicle.
