Hitches It is important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you will need the right hitch. Here are some rules to follow: • The bumpers on your vehicle are not 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. • Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, remember to seal the holes later when you remove the hitch. If you do not seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle. See Engine Exhaust on page 163. Dirt and water can, too. Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting 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 attaching safety chains and do not attach them to the bumper. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground. Trailer Brakes If your trailer weighs more than 1,000 lbs (450 kg) loaded, then it needs its own brakes - and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you will be able to install, adjust, and maintain them properly. Because your vehicle may have anti-lock brakes, do not try to tap into your vehicle's brake system. If you do, both brake systems will not work well, or at all. 418
