Will any holes be made in the body of the vehiclewhen the trailer hitch is installed? If so, be sure toseal the holes when the hitch is removed. If theyare not sealed, deadly carbon monoxide (CO) fromthe engine's exhaust can get into the vehicle. SeeEngine Exhaust on page 3‑36. Sealing the holeswill also prevent dirt and water from entering thevehicle.Safety ChainsAlways attach chains between the vehicle and thetrailer. Cross the safety chains under the tongue of thetrailer to help prevent the tongue from contacting theroad if it becomes separated from the hitch. Instructionsabout safety chains may be provided by the hitchmanufacturer or by the trailer manufacturer. Follow themanufacturer's recommendation for attaching safetychains and do not attach them to the bumper. Alwaysleave just enough slack so the rig can turn.
