4. Remove the wheel wrench, jack and compact spare
tire from the trunk. See ªCompact Spare Tireº later
in this section for more information about the
compact spare tire.
The tools you'll be using include the jack (A) and the
wheel wrench (B).
Removing the Wheel Cover
Models with Center Wheel Cover
For models having aluminum wheels with a center
wheel cover, use the flat end of the wheel wrench to
gently pry the wheel covers off. Be careful not to scratch
the aluminum wheel edge and don't try to remove it
with your hands.
For models having wheel nuts exposed, use the wheel
wrench to remove the wheel nut covers.

5-23 Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.

5-24
2. Find the jacking location from the diagrams above
and corresponding hoisting notches located in the
plastic molding. The front location is 8.5 inches
(21 cm) from the rear edge of the front wheel well,
and the rear location is 3.5 inches (8.5 cm) from the
front edge of the rear wheel well.
The notches may also be labeled ªJACKº with an
arrow pointing to the jacking location on the vehicle.
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. Turn the jack handle counterclockwise to lower the
jack lift head until the jack fits under the vehicle.
4. Raise the jack until the metal flange fits firmly into
the channel of the jack head.
5. Put the compact spare tire near you.

5-25
6. Raise the vehicle by turning the jack handle clockwise.
Raise the vehicle far enough off the ground for the
compact spare tire to fit under the vehicle.
7. Remove all wheel nuts and take off the flat tire.
8. 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.

5-26
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. Place the compact
spare tire on the
wheel
-mounting
surface.
10. Put the wheel nuts back
on with the rounded end
of the nuts toward the
wheel. Tighten each nut
by hand until the wheel
is held against the hub.
11. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.

5-27
12. Tighten the wheel
nuts firmly in a
crisscross sequence
as shown.
If your vehicle is equipped with wheel nut covers,
screw them on with your fingers, then tighten
one
-quarter turn with the wheel wrench.
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.

5-28
13. Don't try to put a wheel cover on your compact
spare tire. It won't fit. Store the wheel cover and
lug nut caps in the trunk until you have the flat tire
repaired or replaced.
NOTICE:
Wheel covers won't fit on your compact spare.
If you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.
Storing the Flat 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.
After you've put the compact spare tire on your vehicle,
you'll need to store the flat tire in your trunk.
Store the flat tire as far forward in the trunk as possible.
Store the jack and wheel wrench in their compartment in
the trunk. For storage, the jack must be raised until the
screw end is flush with the edge of the jack.

5-29 Storing the 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.
The compact spare is for temporary use only. Replace
the compact spare tire with a full
-size tire as soon as
you can. See the storage instructions label for
information on how to properly position and store

Compact Spare Tire
Although the compact spare tire was fully inflated
when your vehicle was new, it can lose air after a
time. Check the inflation pressure regularly. It should
be 60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full
-size tire
repaired or replaced where you want. Of course, it's best
to replace your spare with a full
-size tire as soon as you
can. Your spare will last longer and be in good shape in
case you need it again.
NOTICE:
When the compact spare is installed, don't take
your vehicle through an automatic car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don't use your compact spare on other vehicles.
And don't mix your compact spare tire or wheel with
other wheels or tires. They won't fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won't fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don't use tire chains on your
compact spare.

5-31
If You're Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin
your wheels too fast. The method known as ªrockingº
can help you get out when you're stuck, but you must
use caution.
CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured. And,
the transaxle or other parts of the vehicle can
overheat. That could cause an engine
compartment fire or other damage. When you're
stuck, spin the wheels as little as possible. Don't
spin the wheels above 35 mph (55 km/h) as shown
on the speedometer.
NOTICE:
Spinning your wheels can destroy parts of your
vehicle as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see ªTire Chainsº in the Index.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. You should turn
your traction control system off. See ªTraction Control
Systemº in the Index. Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. Release the accelerator pedal while
you shift, and press lightly on the accelerator pedal
when the transaxle is in gear. By slowly spinning your
wheels in the forward and reverse directions, you will
cause a rocking motion that may free your vehicle. If
that doesn't get you out after a few tries, you may need
to be towed out. If you do need to be towed out, see
ªTowing Your Vehicleº in the Index.
