How to Add Fluid When to Check and What to Use
Here’s how to add
fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level
up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch system in your vehicle is
self-adjusting.
A slight amount of play (114 inch to
1/2 inch or 6 mm to 12 mm) in the pedal is normal.
It isn’t
a good idea to “top off’ your clutch fluid. Adding
fluid won’t correct
a leak. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired. Refer
to the Maintenance
yk I Schedule, Owner Checks
and
Services,
to determine
how often you should check
the fluid level in your clutch
master cylinder reservoir
and for the proper fluid.
See “Owner Checks
and Services” and “Recommended Fluids and
Lubricants” in the Index.
How to Check
The proper fluid should be added if the level does not
reach the bottom of the diaphragm when it’s in place in
the reservoir. See the instructions on the reservoir cap.

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.
If you have rear drum brakes, they don’t have wear
indicators, but if you ever hear
a rear brake rubbing
noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each
time the tires are removed for rotation or changing.
When you have the front brake pads replaced, have
the
rear brakes inspected, too.
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 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.
Your vehicle was designed and tested with top-quality
GM brake parts. 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 approved
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.

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.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl
or leather with a clean, damp cloth.
Your GM dealer has two cleaners, a solvent-type spot
lifter and
a foam-type powdered cleaner. They will clean
normal spots and stains very well.
Do not use them on
vinyl or leather.
Here are some cleaning tips:
1. Always read the instructions on the cleaner label.
2. Clean up stains as soon as you can -- before they set.
3. Use a clean cloth or sponge, and change to a clean area
often.
A soft brush may be used if stains are stubborn.
4. Use solvent-type cleaners in a well-ventilated area
5. If a ring forms after spot cleaning, clean the entire

Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If you need to use a solvent:
1.
2.
3.
4.
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside of the stain, “feathering” toward the center.
Keep changing to a clean section
of the cloth.
When you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
Fabric Protection
Your vehicle has upholstery and carpet that has been
treated with Scotchgard” Fabric Protector, a
3M
product. It protects fabrics by repelling oil and water,
which are the carriers of most stains. Even with this
protection,
you still need to clean your upholstery and
carpet often to keep it looking new.
Further information on cleaning is available by calling 1-800-433-3296 (in Minnesota,
1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them to spread.

1 teaspoon (5 ml) of baking soda to 1 cup (250 ml)
of lukewarm water.
4. If needed, clean lightly with solvent-type cleaner.
Combination Stains
Stains caused by candy, ice cream, mayonnaise, chili
sauce and unknown stains can be removed as follows:
1. Carefully scrape off excess stain.
2. Clean with cool water and allow to dry.
3. If a stain remains, clean it with solvent-type cleaner. Use warm water and
a clean cloth.
0 Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal
links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse
with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can “borrow” one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses
with a fuse extractor. The fuse
extractor is mounted to the fuse block access door.
To
remove fuses if you don’t have a fuse extractor, hold the
end
of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses located behind the fuse block
access door. These can be used to replace a bad fuse.
However, make sure
it is of the correct amperage.
