6. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off
the ground for the compact spare tire to attach
to the vehicle.
7. Remove all wheel nuts and take off the
flat tire.
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 changing a wheel, remove
any rust or dirt from the places where the
wheel attaches to the vehicle. In an
emergency, a cloth or a paper towel can
be used to do this; but be sure to use a
scraper or wire brush later, if needed, to
get all the rust or dirt off.
8. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and
spare wheel.
