Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are inflated to the upper limit for cold tires. You will find these numbers on the Certification/Tire Label at the rear edge of the driver's door, or see Loading Your Vehicle on page 332. Do not go over the GVW limit for your vehicle, including the weight of the trailer tongue. If you do, remember to seal the holes 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 140. 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. 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: • If you will be pulling a trailer that, when loaded, will weigh more than 2,000 lbs (900 kg), use a properly mounted, weight-carrying hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling while driving. • Will you have to make any holes in the body of your vehicle when you install a trailer hitch? 345
