9. Tighten the wheel nuts
firmly in a crisscross
sequence as shown.
I
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 the wheel cover on your compact spare
tire. It won’t
fit. Store the wheel cover in the trunk until
you have the flat tire repaired or replaced.

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

Storing the Flat Tire and Tools
~~
F< .&.ye ~ __
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. 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.

Con 1ct 5 Tirt
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.
L
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.
NOTICE:
Spinning your wheels can destroy parts of you%
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 Buick 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).
A CAUTION:
I
The brake wear warning so Id 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 Travel
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.
ProCarManuals.com
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
Rough ride
Needless damage from road hazards.
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 inspected every 6,000 to 8,000 miles
(10
000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, 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.
6-36
ProCarManuals.com
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.) 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:
0
0
0
0
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.
6-37
ProCarManuals.com
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information 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.
Mixing tires coula 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 four wheels.
It’s all right to drive with your compact spare,
though. 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
