CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after 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 needed, to
get all the rust or dirt off.

dirt from the wheel
bolts, mounting
surfaces and
spare wheel.
10. Place the compact spare tire on the
wheel-mounting surface.

the nuts toward the wheel. Tighten each nut
by hand clockwise until the wheel is held
