Storing a Flat or Spare Tire and Tools
I
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.
NOTICE:
An aluminum wheel with a flat tire should always
be stored under the vehicle with the hoist.
However, storing it that way for an extended
period could damage the wheel.
To avoid this,
have the wheel repaired as soon as possible.
Follow this diagram to store the spare or flat tire.

1. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed down and to the rear.
2. Pull the retainer through the wheel.
3. Put the chisel end of the wheel wrench, on an angle,
through the hole
in the rear bumper and into the hoist
shaft. Turn the
wheel wrench to the right until the
tire is raised against the underside of the vehicle.
You will hear two "clicks"
when the tire is secure,
but
pull on the tire to make sure.
Return the jack. wheel wrench
and wheel blocks to the
proper location
in your vehicle's rear area. Secure the
items
and replace the jack cover.

A CAUTION: A --
Make sure the tire and carrier are secure.
Driving with the tire or carrier unlatched could
injure pedestrians or damage the vehicle.
Compact Spare Tire (If Equipped)
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 Wa).
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 wl~eel 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.
If you let your tires spin at high speed, they can
explode, and you or others could be in,jured. And,
the transmission 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 kmh) 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 transmission back
and forth, you can destroy your transmission.
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. 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 transmission is in gear. If
that doesn't get you out after a few tries, you may need
to be towed out. Or, you can use your recovery hooks
if
your vehicle has them. If you do need to be towed out,
see "Towing Your Vehicle''
in the Index.
Using the Recovery Hooks
Your vehicle is equipped with recovery hooks. The
recovery
hooks are provided at the front of your vehicle.
You may need to use them
if you're stuck off-road
and need to be pulled to someplace where you can
continue driving.

How to Check Lubricant
When to Check Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant. See “Periodic Maintenance
Inspections”
in the Index.
If the level is below the bottom of the filler plug hole,
you’ll need to
add some lubricant. Add enough lubricant
to raise the level to the bottom
of the filler plug hole.

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your vehicle has four-wheel disc 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).
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.

1 NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
ProCarManuals.com

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 bra
cz k es.
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.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.’’
.e 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.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
Replacing Brake System Parts
The braking system on a modern vehicle is complex.
Its many parts have to be
of top quality and work well
together
if the vehicle is to have really good braking.
Your vehicle was designed and tested
with top-quality
GM brake parts. When you replace parts of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved
GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come
to expect can change in many
other ways
if someone puts in the wrong replacement
brake parts.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for
a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.

Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to I3 000 km). Any time you notice unusual
wear, rotate your tires as
soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When
It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
lrniform wear for all tires on the vehicle. The first
rotation is the most important. See ”Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your
tires, always use the correct rotation
pattern shown here.
If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown
on the
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque’‘ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make 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 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. (See
“Changing a Flat Tire” in the Index.)

I CAUTION:
Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires of different sizes may also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
It’s
all right to drive with your compact spare
(if you have one). It
was developed for use on
your vehicle.
A CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires with the wheels on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
