5-19 Removing the Spare Tire and Tools
The equipment you'll need
is in the trunk. Turn the
center retainer nut on the
compact spare tire cover
counterclockwise to remove
it. Lift and remove the
cover. See ªCompact Spare
Tireº later in this section for
more information about the
compact spare tire.
You will find the jacking instructions label on the
underside of the tire cover.
Turn the wing nut
counterclockwise and
remove it. Then lift off the
adapter and remove the
compact spare tire.Remove the jack and wrench from the trunk. Your
vehicle's jack and wrench are stored in a foam tray.
The tools you'll be using include the jack (A) and
the wrench (B).

5-20 Removing the Flat Tire and Installing the
Spare Tire
1. On vehicles equipped with plastic wheel covers,
completely loosen the wheel nut caps, but do not try
to remove the caps from the cover.
2. Give the cover a sharp pull or gently pry on the edge
of the cover to remove it from the wheel.
3. Some models are equipped with aluminum wheels.
Remove the center cover to find the wheel nuts.
Carefully use the wedge end of the wheel wrench
to pry the center cover off.
4. Then use the wrench to loosen all the wheel nuts.
Don't remove them yet.

5. Position the jack and raise the jack head until it fits
firmly into the notch in the vehicle's frame nearest
the flat tire. Put the compact spare tire near you.
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.

6. Raise the vehicle by turning the wrench clockwise.
Raise the vehicle far enough off the ground so there
is enough room for the compact spare tire to fit.
7. Remove all of the wheel nuts.
8. Then 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. 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.
11. Lower the vehicle by turning the wrench
counterclockwise. Lower the jack completely.

12. Tighten the wheel
nuts firmly in a
crisscross sequence,
as shown.
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
100 lb
-ft (140 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.
Don't try to put a wheel cover on your compact spare
tire. It won't fit. Store the wheel cover and wheel nut
caps in the trunk until you have the flat tire repaired
or replaced.
NOTICE:
Wheel covers won't fit on your compact spare
tire. If you try to put a wheel cover on your
compact spare tire, you could damage the cover
or the spare.
