Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
NOTICE:
Raising your vehicle with the jack improperly
positioned will damage the vehicle or may allow
the vehicle to
fall off the jack. Be sure to fit the
jack lift head into the proper location before
raising your vehicle.

I a 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.
b, 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.
6. Replace the wheel nuts
with the rounded end
of the nuts toward the
wheel. Tighten each wheel
nut by hand using
the wheel wrench until
the wheel is held against
the hub.

Improperly tightened wheel nuts can lead to
