A good time to check your automatic
transaxle fluid level
is when the engine
oil is changed. Refer to the Maintenance
Schedule to determine when to change
your fluid. See the

Because this operation can be a little
difficult, you may choose to have this

level should be up to
HOT or a little

Power Steering Fluid
How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
H mark.
When the engine compartment is
cool, the level should be at the
C
mark.
What to Add:
Refer to the Maintenance Schedule to
determine what kind of fluid to use. See
the
Index under Fluids G Lubricants.
When adding power steering fluid
or making a complete fluid change,
always use the proper fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.
Windshield Washer Fluid
To Add:
Open the cap labeled WASHER
FLUID ONLY. Add washer fluid until
the bottle is full.

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
