Removing the Flat Tire and Installing the
Spare Tire
1. If your vehicle has
aluminum wheels, use
the handle of the folding
Then, with the other end of the wrench, loosen the nuts.
2. If your vehicle has the plastic “bolt-on” wheel
covers, you cannot separate the nylon wheel
nut caps
from the cover. Loosen them completely using the
folding wrench, and remove the wheel cover.
If the
wheel nut caps have been completely loosened, the
wheel cover
will come off easily.

3. Loosen the wheel nuts
-- but do not
remove them
-- using
the folding wrench.
(Turn the handle about
180 degrees, then flip
the handle back to the
starting position. This avoids taking
the
wrench off the lug
I nut for each turn.)

4. Near each wheel, there
is a notch in the
vehicle’s body. Position
the jack and raise the
jack head until it fits
firmly into the notch in
the vehicle’s frame
nearest the flat tire.
NOTICE: I
Do not place the jack under the rear axle control
arms. Only use the areas shown for proper
jack location. 1
DO not raise the vehicle yet. Put the compact spare tire
near you.

A 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.
A 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. Attach the folding
wrench to the jack, and
rotate the wrench to the
right to raise the jack
head a few inches.
6. Raise the vehicle by rotating the folding wrench to
the right in the jack. Raise the vehicle far enough
off
the ground so there is enough room for the spare tire
to fit.
7. Remove all the wheel nuts and take off the flat tire.

8. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
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.
1 A CAUTION:
I-
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. Install the spare tire and 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.

10. Lower the vehicle by attaching the folding wheel
wrench to the jack and rotating the wrench to the
left. Lower the jack completely.
I 11. Tighten the wheel
A CAUTION:
nuts firmly in
a criss-cross
sequence, as shown.
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 Nom).

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 the compact spare tire. It
won’t fit. Store the wheel cover securely
in the rear of the
vehicle
until you have the flat tire repaired or replaced.
I 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 a Flat or Spare Tire and Tools
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.
Lay the tire near the rear of the vehicle with the valve
stem down. Slide the cable retainer through the center
of
the wheel and start to raise the tire. When the tire is
almost in the stored position, turn the tire
so the valve is
towards the rear
of the vehicle. This will help when you
check and maintain tire pressure in the spare.
Keep raising the wheel until you hear the hoist
mechanism click twice. This means the wheel is firmly
stored against the underside
of the vehicle. Push
against the wheel to be sure it does not move and is
stored securely.

NOTE: INSTALL BOlTOM OF BAG FIRST
TOOL STORAGE
’ BAG & TOOLS
Replace all jacking tools as they were stored in the jack
storage compartment and replace the compartment
cover.
To replace the cover, line up the tabs on the right
of the cover with the slots in the cover opening. Push the
cover
in place and push down the tab so that it rests in
the groove. This secures the cover in place. Unless
you have the plastic “bolt-on” wheel covers, be
sure to also store the center cap. When you replace the
compact spare with a full-size tire, replace the bolt-on
wheel covers and the center cap. Tighten them “hand
tight’’ over the wheel nuts, using the folding wrench.
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.
If You’re Stuck: In Sand, Mud,
Ice
or Snow
What you don’t want to do when your vehicle is stuck is
to spin your wheels too fast. The method
known as
“rocking” can help you get out when you’re stuck, but
you must use caution.
A 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.

I 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 “Tire Chains” 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. If your vehicle
has traction control,
you should turn your traction
control system
off. (See “Traction Control System” 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.
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 “Towing Your Vehicle” in
the Index.

Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that
make a high-pitched warning sound when the brake
pads are worn and new pads are needed. The sound may
come and go or be heard all the time your vehicle is
moving (except when you are pushing
on the brake
pedal firmly).
I A CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in
the proper sequence
to GM specifications.
Your rear drum brakes don’t have wear indicators, but
if you ever hear
a rear brake rubbing noise, have the
rear brake linings inspected immediately. Also, the rear
brake drums should be removed and inspected each time
the tires are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection’’ in Section
7 under
Part
C “Periodic Maintenance Inspections.”
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
