If a Tire Goes Flat
It’s Llnusual for a tire to ”blow out.’ while you’re driving,
especially
if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But
if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your
f-bot off the
accelerator pedal and grip the steering wheel
firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout. particularly on a curve, acts much like a
skid and may require the same conxxtion you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but
YOLI can still steer. Gently
brake to
a stop -- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.
Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers.
c
A CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you
or other
people. You and they could be badly injured.
Find a level place to change your tire.
To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire on the other side of the
vehicle, at the opposite end.
The following steps
will tell you how to use the jack and
change
a tire.

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 stuc
to spin your wheels too fast. The method known
as
:k is
“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 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 km/h) 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 some place where you can
continue driving.

Brake Wear
Your Oldsmobile 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.
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.
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.”
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.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.

6. Put the blade assembly pivot in the wiper arm hook.
Pull
up until the pivot locking tab locks in the
hook slot.
7. Carefully lower the wiper arm and blade assembly
onto the windshield.
Backglass Wiper Blade Replacement
See “Windshield Wiper Blade Replacement” in this
section for instructions on how to change the backglass
wiper blade. The backglass wiper blade will not lock
in
a vertical position like the windshield wiper blade, so
care should be used when pulling it away from
the vehicle.
Tires
Your new Oldsmobile 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 Wmanty booklet
for details. 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 “Loading Your Vehicle” 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.
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 Certificationmire label, which is on the driver’s
door edge, above the door latch, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” 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
0 Bad fuel economy.
NOTICE: (Continued)
I I
NOTICE: (Continued)
i If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once
a month or more. Also, check the
tire pressure
of the spare tire.
If you have a 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 “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.
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
Certificationmire label. Make certain that all wheel nuts
are properly tightened. See
“Wheel Nut Toraue” 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.)

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
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
tire’s rubber.
Buying New Tires
To
find out what kind and size of tires you need, look at
the CertificatiodTire label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC 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 service 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 those 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.
The tire has a puncture, cut or other damage that
can‘t be repaired well because of the size or location
of the damage.
ProCarManuals.com

I
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.
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.
