4. Insert the jack handle into the jack and the wheel
wrench onto the end of the jack handle.
5. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the compact
spare tire to fit underneath the wheel well.
6. Remove all of the wheel nuts by turning them
counterclockwise.
7. Remove the flat tire.
5-69

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.
{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. Install the wheel nuts with the rounded end of the
nuts toward the wheel. Tighten each nut by hand
clockwise until the wheel is held against the hub.
11. Lower the vehicle by turning the wheel 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 come 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 the
proper torque specication. See “Capacities
and Specications” in the Index for wheel nut
torque specication.
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 specication. See “Capacities and
Specications” in the index for the wheel nut torque
specication.Do not try to put a wheel cover on your compact spare
tire. It will not fit. Store the wheel cover in the cargo
area until you have the flat tire repaired or replaced.
Notice:Wheel covers will not t on your compact
spare. If you try to put a wheel cover on the 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.
Store the flat tire in the compact spare tire compartment.
Place the tire in the compartment, then secure the
retainer. Store the jack in its housing in the cargo area.
Secure the jack by turning the retainer clockwise.
Store the tools securely in the foam tray and place the
tray on top of the tire. Replace the trim cover.

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.
Store the compact spare tire in the compact spare tire
compartment. Place the compact spare tire in the
compartment, then secure the retainer. Store the jack in
its housing in the cargo area. Secure the jack by
turning the retainer clockwise. Store the tools securely
in the foam tray and place the tray on top of the
tire. Replace the trim cover.
The compact spare tire is for temporary use only.
Replace the compact spare tire with a full-size tire as
soon as you can. SeeCompact Spare Tire on page 5-72.
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 50 mph
(80 km/h), so you can finish your trip and have your
full-size tire repaired or replaced where you want.
Of course, it is 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.
Do not use your compact spare on other vehicles.
And do not mix your compact spare tire or wheel with
other wheels or tires. They will not fit. Keep your
spare tire and its wheel together.
Notice:Tire chains won’t t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-60.
Headlamp Wiring
The headlamp wiring is protected by fuses, one for each
headlamp, in the fuse block. An electrical overload
will cause the lamps to turn off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
5-82

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
There are spare fuses provided in the engine
compartment fuse block. If you ever have a problem on
the road and do not have a spare fuse, you can borrow
one that has the same amperage. Just pick a feature of
your vehicle that you can get along without — like the
radio or cigarette lighter — and use its fuse, if it is the
correct amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the instrument
panel fuse block and the engine compartment fuse block.
There is a fuse puller located on the engine
compartment fuse block. It can be used to easily
remove fuses from the fuse block.
Instrument Panel Fuse Block
The instrument panel fuse block is located on the end of
the instrument panel, on the driver’s side of the
vehicle. To access the fuses, open the fuse panel door
by pulling out.
To reinstall the door, insert the tabs at the back end
first, then push the door into the instrument panel
to secure it.Sedan shown, Hatchback similar
