The tools you'll be using include the jack (A), wheel
blocks (B), extension (C) and ratchet (D).
Removing the Wheel Covers
You will have to take off hub caps or wheel nut caps to
reach your wheel nuts.
Styled Steel Wheel Shown
If you have a standard steel wheel, carefully pry along
the edge of the hub cap until it comes off. Be careful, the
rim edges may be sharp. Don't try to remove the hub
cap with your bare hands.
If you have the styled steel wheel or aluminum wheel with
plastic nut caps, loosen the plastic nut caps with the ratchet
and socket. Make sure the DOWN side faces you.
To remove the hub cap from the aluminum wheel
without plastic nut caps, fit the flat end of the extension
into the notch. Then, remove the center cap.

CAUTION:
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.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the
jack lift head into the proper location before
raising the vehicle.7. Raise the vehicle by turning the ratchet clockwise.
Make sure the UP mark faces you. Raise the vehicle
far enough off the ground so there is enough room
for the spare tire to fit.
8. Remove all the wheel nuts and take off the flat tire.

9. 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.
10. Put on the spare tire. 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 extension and see your dealer
as soon as possible.
