6. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{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.
{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.
7. Place the spare on the wheel mounting surface.
8. Put the nuts on by
hand. Make sure the
cone-shaped end
is toward the wheel.
Tighten each nut by hand until the wheel is held
against the hub. If a nut can't be turned by
hand, use the wheel wrench and see your dealer
as soon as possible.
