If a Tire Goes Flat
[t’s unusual for a tire to “blow out” while
you’re driving, especially
if you maintain
your tires properly. If air goes out of a
;ire, it’s much more likely to leak out
jlowly. But if you should ever have a
‘blowout,” here are a few tips about what
:o expect and what to do:
[fa front tire fails, the
flat tire will create
3 drag that pulls the vehicle toward that
side. Take your foot off the accelerator
pedal and grip the steering wheel firmly.
Steer to maintain lane position,
then
gently brake to a stop well out of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like a
slud and may require the
same correction 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 you can still steer.
Gently brake to a stop, well
off the road
if possible.
[f a tire goes flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.

Automatic Transmission Fluid
When to Check and Change:
A good time to check your automatic
transmission fluid level
is when the
engine oil is changed. Refer to the
Maintenance Schedule to determine when
to change your fluid. See “Scheduled
Maintenance Services” in the Index.
How to Check:
Because this operation can be a little
difficult, you may choose to have this
done at a Pontiac dealership Service
Department.
If you do it yourself, be sure to follow all
the instructions here, or
you could get a
false reading on the dipstick.
Too much or too little fluid can
damage your transmission. Too much
can mean that some of the fluid could
come out and fall on hot engine parts
or exhaust system, starting a fire. Be
sure to get an accurate reading
if you
check your transmission fluid. Wait
at least 30 minutes before checking
the transmission fluid level if you have
been driving:
When outside temperatures are above
At high speed for quite a while.
In heavy traffic - especially in hot
90°F (32°C).
weather.
While pulling a trailer.
To get the right reading, the fluid should
be at normal operating temperature,
which is 180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: Get
the vehicle warmed up by driving
about
15 miles (24 km) when outside
temperatures
are above 50°F ( 10°C).
If it’s colder than 50°F ( lO”C), drive
the vehicle in
“D’ (Third Gear) until the
engine temperature gage moves and then
remains steady for
ten minutes. Then
follow the hot check procedures.
To check transmission fluid cold: A cold
check is made after the vehicle has been
sitting for eight hours or more with the
engine
off and is used only as a reference.
Let the engine run at idle for five minutes
if outside temperatures are 50°F
(10°C)
or more. If it’s colder than 50°F (lO°C),
you may have to idle the engine longer.
Should the fluid level be low during a
cold check, you must perform a hot check
before adding fluid. This will give you a
more accurate reading of the fluid level.
To check the fluid hot or cold:
0
Park your vehicle on a level place.
With the parking brake applied, place
the shift lever
in “P” (Park).
With your foot on the brake pedal,
move the shift lever through each gear
range, pausing for about three seconds
in each range. Then, position the shift
lever in “P” (Park).
Let the engine
run at idle for three
minutes or more.

Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the brake
fluid level in your master cylinder might
go down. The first is that the brake fluid
goes down to an acceptable level during
normal brake lining wear. When new linings are put in, the fluid level goes
back up. The other reason is that fluid is
leaking out of the brake system. If it is,
you should have your brake system fixed,
since a leak means that sooner or later
your brakes won’t work well, or won’t
work at all.
. . .206
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t
correct a leak. If you add fluid when your
linings are worn, then you’ll have too
much fluid when you get new brake
linings. You should add (or remove)
brake fluid, as necessary, only when work
is done on the brake hydraulic system.
Refer to the Maintenance Schedule to
determine when to check your brake
fluid. See “Periodic Maintenance
Inspections’’ in the Index.
To Check Brake Fluid:
You can check the brake fluid without
takmg
off the cap. Just look at the brake
fluid reservoir. The fluid level should be
above the plastic seam
in the reservoir.
If
it isn’t, have your brake system
checked to see if there
is a leak.
After work is done on the brake hydraulic system, make sure the level is above the
plastic seam, near the base of the filler
neck.
ProCarManuals.com

What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid - such as Delco-
Supreme ll@
(GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the
brake fluid reservoir cap before
removing it.
NOTICE:
Don’t let someone put in the
wrong kind of fluid. For example,
just
a few drops of mineral-based
oil, such as engine oil, in your
brake system can damage brake
system parts
so badly that they’ll
have to be replaced.
Brake fluid can damage paint,
so
be careful not to spill brake fluid on your vehicle. If you
do, wash it
off immediately. See “Appearance
Care”
in the Index.
Brake Wear
Unless you have the four-wheel disc
brake option, your Pontiac has front disc
brakes and rear drum 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).
I NOTICE:
I
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.
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 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.

Service and Appearance Care
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
. . .208
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
catalog 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. Contact your dealer
to learn how to
prepare your vehicle for longer storage
periods.

Service and Appearance Care
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. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air out, 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.
[f you need to replace any of your wheels,
wheel bolts, or wheel nuts, replace them
mly with new
GM original equipment
sarts. This way, you will be sure to have
:he right wheel, wheel bolts, and wheel
nuts for your Pontiac model.
NOTICE:
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer/odometer
calibration, headlight aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to
the body and chassis.
