Adding Coolant
To Check Coolant:
When your engine is cold, the coolant
level should be between the
FULL
COLD mark and FULL HOT. When
your engine is warm, the level should be
up
to FULL HOT, or a little higher.

If you have the optional low coolant
warning light and it comes on when
your engine is running, you’re low on
coolant. Or, if you have the optional

you’re low on coolant.

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.

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.
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t

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.
, If you have too much brake
hid,
it can spill on the
engine. The fluid will burn if the
engine is hot enough.
You or
others could be burned, and your
engine could be damaged. Add
brake fluid only when work is
done on the brake hydraulic
system.

When your brake fluid falls to a low
level, your brake warning light will
come on. A continuous chime will
sound if
you try to drive with this
warning light on. See the
Index under
Brake System Warning Light.
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.
DOT-5 silicone brake fluid can
damage your vehicle. Don’t use
it.
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.

Replacing Brake System Pants
The braking system on a modem 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 catalog number shown on the
original battery’s label.
Jump Starting
For jump starting instructions, see the
Index under Jump Starting.
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.
1
Batteries have acid that can
burn you and gas that can
explode.
You can be badly hurt if
you aren’t careful. See the Index
under Jump Starting for tips on
working around a battery without
getting hurt.
Contact your dealer to learn how
to
prepare your vehicle for longer storage
periods.
