Removing the Flat Tire and Installing
the Spare Tire
1. Turn the wheel wrench counterclockwise to loosen
the wheel nuts. Don't remove the wheel nuts yet.

2. Position the jack under the vehicle. If the flat tire is
on the front of the vehicle, position the jack on the
frame behind the flat tire.
If the flat tire is on the rear of the vehicle, use the
jacking pad provided on the rear axle.
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.

3. Make sure the jack
head is positioned
so that the rear axle
is resting securely
between the grooves
that are on the jack
head. Turn the wheel
wrench clockwise to
raise the vehicle.
Rear Position
Raise the vehicle far enough off the ground so there is
enough room for the spare tire to fit back underneath the
rear of the vehicle.

4. Remove all the wheel
nuts and take off the
flat tire.
5. 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.
6. After mounting the
spare, put the wheel
nuts back on with the
rounded end of the
nuts toward the wheel.
Tighten each wheel nut by hand. Then use the wheel
wrench to tighten the nuts until the wheel is held against
the hub.

7. Turn the wheel wrench
counterclockwise to
lower the vehicle. Lower
the jack completely.
Rear Position
8. Tighten the nuts
firmly in a crisscross
sequence as shown
by turning the wheel
wrench clockwise.
CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
140 lb
-ft (190 N´m).

NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the
wheel nuts in the proper sequence and to the
proper torque specification.
When you reinstall the full-size wheel and tire, you
must also reinstall the center cap. Place the cap on the
wheel and tap it into place until it seats flush with the
wheel. The cap can only go on one way. Be sure to
line up the tab on the center cap with the indentation
on the wheel.
Storing a Flat or Spare Tire and Tools
CAUTION:
Storing a jack, a tire or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
Store the flat tire where the spare tire was stored.

Store the tire under the rear of the vehicle in the spare
tire carrier. To store the tire do the following:
1. Put the tire on the ground at the rear of the vehicle
with the valve stem pointed upward.
2. Tilt the retainer downward and through the wheel
opening. Make sure the retainer is fully seated across
the underside of the wheel.
3. Attach the wheel wrench and extensions together.
Insert the hoist end through the hole in the rear
bumper and into the hoist shaft.
4. Raise the tire part way upward. Make sure the
retainer is seated in the wheel opening.
5. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench until the
tire is secure and the cable is tight. The spare tire
hoist cannot be overtightened.
6. Make sure the tire is stored securely. Push, pull, and
then try to rotate or turn the tire. If the tire moves,
use the wheel wrench to tighten the cable.
Replace the jack, tools and spare tire lock.
