Vehicle Care 10-73 { WARNING Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See If a Tire Goes Flat on page 10‑58. { WARNING Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash. 10. Remove any rust or dirt from the wheel bolts, mounting surfaces, and spare wheel. 11. Place the spare tire on the wheel mounting surface. 12. Put the nuts on by hand by turning them clockwise until the wheel is held against the mounting surface. Make sure the rounded end is toward the wheel. 13. Lower the vehicle by attaching the lug wrench to the jack and turning the wrench counterclockwise. Lower the jack completely. 9. Remove the plastic spare tire heat shield by pulling the rubber latch. Store the plastic spare tire heat shield. See "Storing a Flat or Spare Tire and Tools" later in this section for more information.
