Total Weight on Your Vehicle's Tires Be sure your vehicle's tires are intlated to the l i m i t for cold tires. You'll find these numbers on the Certification label at the rear edge of the driver's door or see"Tire Loading" in the Index. Then be sure you don't go over the CVW limit for your vehicle, including the weight of the trailer tongue. 0 Will you have to make any holes in the body of your vehicle when you install a trailer hitch'? If you do, then be sure to seal the holes later when you remove the hitch. I f you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "Carbon Monoxide'' in the Index). Dirt and water can, too. 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 right hitch. Here are some rules to follow: 0 If you'll be pulling a trailer that, when loaded, will weigh more than 2,000 Ibs. (900 kg), be sure to use a properly mounted, weight-distributing hitch and sway control of the proper size. Thisequipment is very important for proper vehicle loading and good handling when you're driving. 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 i t becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufxturer. Fallow the lnanufacturer's recommendation for attaching safety chains and do not attach them to the bunlper. Always leave just enough slack so you can turn with your rig. And, never allow safety chains to drag on the ground. 4-32
