Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Put the shift lever in PARK (P).
2. Set the parking brake firmly.
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
The following steps will tell you how to use the jack and
change a tire.

5-19 Removing the Spare Tire and Tools
The equipment you'll need is in the trunk.
Instructions for changing your tires are on the inside of
the tire cover.
1. Lift the tire cover to gain access to the spare tire and
jacking equipment. To do this:
Press the area at the front
of the handle so that the
back edge raises.
Grab the handle and
remove the cover.
2. Unscrew the wing nuts to remove the container that
holds the wrench and jack.

5-20
3. Remove the wheel wrench, jack and the spare tire
from the trunk. See ªCompact Spare Tireº later
in this section for more information about the
compact spare.
The tools you'll be using include the jack (A) and the
wheel wrench (B).
Removing the Wheel Cover
Wheel With Cover
If you have an aluminum wheel with a center cover, use
the flat end of the wheel wrench to gently pry the wheel
cover off. Be careful not to scratch the aluminum wheel
edge and don't try to remove it with your hands.
If you have an aluminum wheel without a center cover,
the wheel nuts and wheel nut covers are exposed.
Use the wheel wrench to remove the wheel nut covers.

5-21 Removing the Flat Tire and Installing the
Spare Tire
Wheel Without Cover
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.

5-22
2. Find the jacking location from the diagrams above
and corresponding cutouts in the plastic molding.
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.

5-23
3. Turn the jack handle counterclockwise to lower the
jack lift head until the jack fits under the car.
4. Raise the jack until the metal flange fits firmly into
the channel of the jack head.
5. Put the compact spare near you.
6. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the 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.

5-24
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
spare on the
wheel
-mounting
surface.
10. Replace the wheel nuts
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.

5-25
12. Tighten the wheel
nuts firmly in a
crisscross sequence
as shown.
On the STS, screw on the wheel nut covers 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).

5-26
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 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

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.

the trunk. For storage, the jack must be raised until the
screw end is flush with the edge of the jack.

soon as you can. See the storage instructions label to
