Storing the Flat 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.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in your trunk. Use the
following procedure to secure the flat tire in the trunk.
Put the flat tire in the trunk so the side that faces out
when it is on the vehicle is facing down. The full-size
tire will not fit down into the well. Place it
so the front is
in the well and the rear is out
of the well.
I
Put the bolt through one of the wheel nut holes, install
the retainer over the bolt, then install the wing nut. Put
the spacer and nut next to the tire in the well. Store the
cover as far forward as possible.

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 posted speed limits 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.
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 M) 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 “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 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 Pontiac 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
fldy).
The brake wear warning sound means that sooner
or later
your brakes won't work well. That could
lead to an accident. When you hear the brake wear
warning sound, have
your vehicle serviced.
I 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.
Free movement
of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, 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.
Brake Pedal navel
See your dealer 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 apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

When to Check.
Check your tires once a month or more. ~
Don? forget your compact spare tire. It should be at
60 psi (420 @a).
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires awproperly inflated
simply
by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation I
Tires should be inspected every 6,000 to 8,000 miles
(1.0 000 to 13 000 Ian) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
pos-sible 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
uniform 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.
. ,. ...
Don’t include the compact spare tire in your
tire rotation.

After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information 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.)

Buying New Tires
To find out what lund and size of tires you need, look at
the Tire-Loading Information.labe1.
The tires installed on your vehicle w
a Tire Performance Criteria Specification ("PC Spec)
number on each .tire's sidewall. When you get
new tires,
get ones with that same
TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal sen;ice on
your vehicle.
If your tires have an all-season tread
design, the
TPC number will be followed by an "MS" '
(for mud and snow).
If you ever replace your tires with tho'se not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
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. ,( ' . ; I :* ' '.i i.!;:; i

Temperature -- A, B, C
The temperature grades are A (the highest), B, and C,
representing he tire's resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on
a specified indoor laboratory
test wheel. Sustained
hgh temperature can cause the
material
of the tire to degenerate- and reduce tire life, and
excessive temperature
can lead to sudden tire failure.
The grade 'C corresponds to a level of performance
which all passenger
car tires must meet under the
Federal Motor Vehicle. Safety Standard
No. 109. Grades
€3 and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: ne temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately 'or in Combination,
can cause heat buildup and possible tire failure.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully
at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have your wheels
aligned again. However, if you notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may-need to be reset.
If you notice your
vehicle vibrating when driving on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel *at is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts .and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which
can sometimes be repaired). See your
Pontiac dealer if any
of these conditions exist.
ProCarManuals.com

Your dealer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the same way as the one it replaces.
If you need to replace any of your wheels,. wheel bolts
or wheel nuts, replace them only with new GM original
equipment
parts. This way, you will be sure to have
the right wheel, wheel bolts and wheel nuts for your
Pontiac model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and ,handling of your
vehicle, make your tires lose
air and make you
lose control. You could
have a collision in which
you or others could be injured. Always use
the correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance
to the body and chassis.
See "Changing a Flat Tire" in the Index\for
