If the fluid level is low, add only enough
of the proper fluid to bring the level up to
the “COLD’ area for a cold check or the
“HOT” area for a hot check. It doesn’t
take much fluid, generally less than a pint.
Don’t overfill. We recommend you use
only fluid labeled DEXRON@-I11 or
DEXRON@-IIE, because fluids with
that label are made especially for your
automatic transmission. Dama
e caused
by fluid other than DEXRON
-111 or
DEXRON@-IIE is not covered by your
new vehicle warranty.

Manual Transmission Fluid
How to Check:
Because this operation can be 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.
NOTICE:
Too much or too little fluid can
damage your transmission.
Too rriuch
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.
Check the fluid level only when your
engine is off, the vehicle is parked on a
level place and the transmission is cool
enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to
the bottom of the filler plug hole.
3. If the fluid level is good, install the
plug and be sure it is fully seated. If
the fluid level is low, add more fluid
as described in the next steps.
How to Add Fluid:
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 in your vehicle is
self-adjusting. The clutch master cylinder
reservoir is filled with hydraulic clutch
fluid.
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.
When to Check and What to Use:
Refer to the Maintenance Schedule 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
is below the “STEP’ mark on the
reservoir. See the instructions on the
reservoir cap.
Rear Axle
When to Check and Change Lubricant:
Refer to the Maintenance Schedule to
determine how often to check the
lubricant and when to change
it. See
“Periodic Maintenance Inspections” in
the Index.
How to Check Lubricant:
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use
Standard Differential
Use Axle Lubricant (GM Part No.
1052271) or SAE 80W-90 GL-5 gear
lubricant.
Limited-Slip Differential
To add lubricant when the.leve1 is
low, use Axle Lubricant (GM Part
No.
105227 1) or SAE 8OW-90 GL-5 gear
lubricant. To completely refill after
draining, add
4 ounces ( 1 18 ml) of
Limited-Slip Differential Lubricant
Additive (GM
Part No. 1052358). Then
fill to the bottom of the filler plug hole
with Axle Lubricant (GM
Part No.
12345977) or SAE 8OW-90 GL-5 gear
lubricant.
Engine Coolant
The following explains your cooling system and how to add coolant when
it is low. If you have a problem with
engine overheating or if you need to add
coolant to your radiator, see “Engine Overheating” in the Index.

Service and Appearanc’e Care
The proper coolant for your Pontiac will:
0
Give freezing protection down to
-34°F (-37°C).
Give boiling protection up to 262°F
(128°C)
.
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as
they
should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled coolant
conforming to GM Specification 1825M
with a complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost wouldn’t be covered by your war-
ranty. Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts.
Adding Coolant
To Check Coolant: When your engine is
cold, check the dipstick on the cap of the
coolant recovery tank. The coolant level should be “COLD,” or a little higher.
When your engine is warm, the level on
the dipstick should be up to
“HOT,” or a
little higher.

Radiator Pressure Cap (All Engines)
NOTICE:
Your radiator cap is a 18 psi (124 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage from over-
heating. Be sure the arrows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace your radiator pressure
cap,
an AC@ cap is recommended.
Thermostat
Engine coolant temperature is controlled
by a thermostat in the engine coolant
system. The thermostat stops the flow of
coolant through the radiator until the
coolant reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.

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.

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.
