Hitches It's important to have the correct hitch equipment. Crosswinds, large trucks going by and rough roads are a few reasons why you'll need the righthitch. Here are some rules to follow: 0 Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attachingsafety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sureto seal the holes later when you remove the hitch.If you don't seal them, deadlycarbon monoxide (CO) from your exhaust can get intoyour vehicle (see"Carbon Monoxide" in the Index). Dirt and water can, too. The bumpers on your vehicle arenot intended for hitches. Do not attach rental hitches or other bumper-type hitches to them. Use only a frame-mounted hitch that does not attach to the bumper. Trailer Brakes Does your trailer have its own brakes? Be sure toread and follow the instructions forthe trailer brakesso you'll be able to install, adjust maintain them and properly. Because you have anti-lock brakes, do not try to tap into your vehicle's brake system. If you do, both brake systemswon't work well, or at all. 0 4-33
