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.

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.
9. Install the compact spare tire. Put the wheel nuts
back on with the cone end of the nuts toward the
wheel. Tighten each nut by hand or with the wrench
until the wheel is held against the hub.
