Inspections”. could result in costly brake repair.
manual under Part C “Periodic Maintenance
Same 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.
See “Caliper/Knuckle Maintenance Inspection’’ in
Section
7 of this manual under Part C “Periodic
Maintenance Inspections.”
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 brakes replaced, have the rear
brakes inspected, too.
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 moderate brake stop, your disc
brakes adjust for wear.
If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then -- very carefully -- make
a few moderate brake stops about every 1,000 miles
(1 600 km), so your brakes will adjust properly.
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 Pontiac 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.
Battery
Every new Pontiac has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get
one that has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days
or more, take off the black, negative
(-) cable from
the battery. This will help keep your battery from
running down.
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See
‘‘Jump Starting” in the Index
for tips on working around a battery without
getting hurt.

Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio
system, see “Theft-Deterrent
Feature”
in the Index.

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
Pontiac dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
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
CM
original equipment parts. This way, you will be sure to
have the right wheel, wheel. bolts and wheel nuts
for
your Pontiac 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 or
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.

Main Fuse Block
The other is in the engine compartment. Open the cover
on either of the boxes to expose the €uses.
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 correct size.
If
you ever have a problem on the road and don’t have a
spare €use, you can “borrow”
one. Just pick some
feature
of your car that you can get along without -- like
the radio or cigarette lighter -- and use its fuse, if it is
the size you need. Replace it as soon as you
can.

Starter Switch Check When
you are doing this check, the vehicle could
move suddenly.
If it does, you or others could be
injured. Follow the steps below. Brake-Transmission Shift Interlock
(BTSI) Check
(Automatic Transmission)
1.
2,
3.
Before you start, be sure you have enough room
around the vehicle.
Firmly apply
both the parking brake (see “Parking
Brake” in the Index if necessary) and the regular brake.
NOTE: Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it starts.
On automatic transmission vehicles, try to start the
engine in each
gear. The starter should work only in
PARK (P) or NEUTRAL (N). If the starter works in
any other position, your vehicle needs service.
On manual transmission vehicles, put the
shift lever
in
NEUTRAL (N), push the clutch down halfway
and try to start the engine. The starter should work
only when the clutch is
pushed down all the way to
the floor. If the starter works when the clutch isn’t
pushed
all the way down, your vehicle needs service.
When you are doing this check, the vehicle could
move suddenly. If it does, you or others could be
injured. Follow the steps below.

3.
Before you start, be sure you have enough room
around the vehicle. It should be parked
on a
level surface.
Firmly apply the parking brake (see “Parking Brake”
in the Index if necessary).
NOTE: Be ready to apply the regular brake
immediately
if the vehicle begins to move.
With the engine off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake, try to move the shift lever out of
PARK (P) with normal effort. If the shift lever
moves out
of PARK (P), your vehicle’s BTSI
needs service.
