Using the hitch Your vehicle uses a load carrying hitch. Because this type of hitch places the tongue load of a trailer on the rear wheels of your vehicle, you must distribute the load in your trailer so that only 10 to 15% of the total weight of the trailer is on the tongue. Tie down the load so that it does not shift and change the weight on the hitch. This will prevent damage to your vehicle and make your vehicle easier to handle. Connecting the safety chains Always attach the trailer's safety chains to your vehicle. They help protect your trailer if the hitch breaks. To connect the trailer's safety chains: 1. Cross the chains under the trailer tongue and attach them to your vehicle's frame or hook retainers. Never attach the safety chains to your vehicle's bumper. The bumper is not designed to bear the weight of a trailer. Make sure that you leave enough slack in the chains to allow you to turn corners. 2. If you use a rental trailer, follow the instructions that the rental agency gives you. 182
