5-25 Removing the Flat Tire and Installing
the Spare Tire
1. If your vehicle has
aluminum wheels,
use the handle of the
folding wrench to pry
the large center cap off.
Then, with the other end of the folding wrench,
loosen the nuts.
If your vehicle has the plastic ªbolt-onº wheel
covers, loosen them completely using the folding
wrench, and remove the wheel cover.

5-27
3. 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:
Do not place the jack under the rear axle control
arms. Only use the areas shown for proper jack
location.
Do not raise the vehicle yet. Put the compact spare
tire near you.
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.

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

5-30
10. 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 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).
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.
11. 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.
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.

5-31 Storing a Flat or 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.
1. Lay the tire near the rear of the vehicle with the
valve stem down.
2. Remove the small center cap by tapping the back of
the cap with the extension of the shaft.3. Slide the cable retainer through the center of the
wheel and start to raise the tire.
Make sure the retainer is fully seated across the
underside of the wheel.
4. 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.
5. Raise the tire fully against the underside of the
vehicle. Continue turning the folding wrench until
the tire is secure and the cable is tight. The spare tire
hoist cannot be overtightened.

5-33
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
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin
your wheels too fast. The method known as ªrockingº
can help you get out when you're stuck, but you must
use caution.

6-40
5. Push the release clip at the connecting point of the
blade and the arm up and pull the blade assembly
down toward the glass to remove it from the
wiper arm.
6. Push the new wiper blade securely on the wiper arm
until you hear the release clip ªclickº into place.
7. Push the release clip, from Step 4, down to secure
the wiper blade into place.
Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your Oldsmobile Warranty booklet for details.
CAUTION:
Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result of too much friction.
You could have an air
-out and a serious
accident. See ªLoading Your Vehicleº in
the Index.

Underinflated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)

6-41
CAUTION: (Continued)

Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.

Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
Inflation -- Tire Pressure
The Certification/Tire label, which is on the rear edge of
the driver's door, shows the correct inflation pressures
for your tires when they're cold. ªColdº means your
vehicle has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:

Too much flexing

Too much heat

Tire overloading

Bad wear

Bad handling

Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards.

6-42
When to Check
Check your tires once a month or more.
Don't forget your compact spare tire. It should be
at 60 psi (420 kPa).
How to Check
Use a good quality pocket
-type gage to check tire
pressure. You can't tell if your tires are properly 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
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 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 ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for more
information. Make sure the spare tire is stored securely.Push, pull, and then try to rotate or turn the tire. If it
moves, use the folding wrench to tighten the cable. See
ªStoring a Flat or Spare Tire and Toolsº in the Index.
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 ªScheduled Maintenance
Servicesº in the Index for scheduled rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.

6-43
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
Certification/Tire label. Make certain that all wheel nuts
are properly tightened. See ªWheel Nut Torqueº in
the Index.
CAUTION:
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 ªChanging a Flat Tireº in the Index.)
When It's Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:

You can see the indicators at three or more places
around the tire.

You can see cord or fabric showing through the
tire's rubber.

The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.

The tire has a bump, bulge or split.

The tire has a puncture, cut or other damage that
can't be repaired well because of the size or location
of the damage.
