7. Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel. CAUTION: Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident. 8. Place the compact spare tire on the wheel-mounting surface. CAUTION: Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if you need to, to get all the rust or dirt off. Reinstall the wheel nuts with the rounded end of the nuts toward the wheel. Make sure each wheel stud is centered in each wheel hole while tightening the nuts. Tighten each nut by hand until the wheel is held against the hub. 9. Lower the vehicle by turning the wheel wrench counterclockwise on the jack. Lower the jack completely. 5-24
