Downloaded from www.Manualslib.com manuals search engine 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.
Your rear drum brakes don’t have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
should be removed and inspected each time the tires are
removed for rotation or changing. When
you have the
front brakes replaced, have the rear brakes inspected, too.
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 make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes
a few times.
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.
Vehicles we design and
test have top-quality GM brake
parts in them, as your vehicle does when it is new. 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 genuine
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.

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.
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.

When rotating your tires, always use one of the correct
rotation patterns shown here. After the tires have been rotated, adjust the front and rear
inflation pressures as shown on the
Certificatioflire 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.)

Downloaded from www.Manualslib.com manuals search engine 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.
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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest, are A, B,
and C, and they represent the tire’s ability to stop
on wet pavement as measured under controlled
conditions on specified government test surfaces
of asphalt and concrete. A tire marked C may have
poor traction performance.
6-45

Downloaded from www.Manualslib.com manuals search engine Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the 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 high 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
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The 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 that 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
GM dealer if any of these conditions exist.
Your dealer
will know the kind of wheel you need.
6-46

Downloaded from www.Manualslib.com manuals search engine 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 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/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
more information.
Used Replacement Wheels
Putting
a used wheel on wr vehicle is
dangerous. You can’t know how it’s been used
or
how many miles it’s been driven. It could fail
suddenly and cause an accident.
If you have to
replace a wheel, use a new
GM original
equipment wheel.

NOTICE:
If your vehicle has P235/75R15, P235/70R15 or
31xlOSOR15LT/C size tires, don’t use tire chains.
They can damage your vehicle.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE Class “S” type chains that are the proper
size for your tires. Install them on the drive axle
tires (four-wheel-drive vehicles can use chains on
both axles) and tighten them
as tightly as possible
with the ends securely fastened. Drive slowly and
follow the chain manufacturer’s instructions.
If
you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on
will damage
your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame if you strike a
match or get them
on a hot part of the vehicle. Some are
dangerous if
you breathe their fumes in a closed space.
When you use anything from a container to clean your
vehicle, be sure to follow the manufacturer’s warnings
and instructions. And always open your doors
or
windows when you’re cleaning the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all
be hazardous -- some more than
others
-- and they can all damage your vehicle, too.
6-48

Downloaded from www.Manualslib.com manuals search engine necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior pamted surfaces are subject
to aging, weather
and chemical fallout that can take their toll over a period
of years.
You can help to keep the paint finish looking
new by keeping your vehicle garaged
or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is
usually
needed. However, you may use GM Chrome Polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap
to clean aluminum. A
coating of wax, rubbed to high polish, is recommended
for all bright metal parts.
Aluminum Wheels (If So Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with a soft clean towel.
A wax
may
then be applied. The
surface of these wheels is similar to the painted
surface of your vehicle. Don’t
use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes
on them because you could
damage
the surface.
Don’t take your vehicle through
an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
Tires
To clean your tires, use a stiff brush with a tire cleaner.
I NOTICE:
When applying a tire dressing always take care
to wipe
off any overspray or splash from all
painted surfaces
on the body or wheels of the
vehicle. Petroleum-based products may damage
the paint finish.
