1 L% CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system
is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Your engine could catch fire and you or others
could be burned. Use a
50/50 mixture of clean,
drinkable water and DEX
COOL@ coolant.
Notice: In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts. Use the recommended coolant and the proper
coolant xture.
-
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

3. Then fill the coolant surge tank with the proper
mixture, to the hash mark on the label. Wait
about five minutes, then check to see
if the level is
below the hash mark. If the level is below the
hash mark, add additional coolant to bring the level
up to the hash mark. Repeat this procedure until
the level remains constant at the hash mark
for at least five minutes.
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level
is lower than
the FULL
COLD mark, add more of the proper
mixture to the coolant surge tank until the
level reaches the FULL COLD mark.

5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer,
if necessary.
Power Steering Fluid

L- A
When to Check Power Steering Fluid
See Engine Compartment Overview on page 5-12
for reservoir location.
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
5-36

How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
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.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
To determine what kind of fluid to use, see Part D:
Recommended Fluids and lubricants on page 6- 15.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you
will
be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing. See
Engine
Compartment Overview on page
5-12 for reservoir
location.

the vehicle.
Notice:
e
@
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full. When
using concentrated washer
fluid, follow
the manufacturer’s instructions for adding
water.
Don’t mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts
of the washer system. Also, water doesn’t
clean as well
as washer fluid.
Fill your washer fluid tank only three-quarters
full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if
it is completely full.
Don’t use engine coolant (antifreeze) in your
windshield washer. It can damage your
washer system and paint.

Brakes
Brake Fluid
A
Your brake master cylinder reservoir is on the driver’s
side
of the engine compartment. It is filled with
DOT-3 brake fluid. See Engine Compartment Overview
on page 5- 12.
There are only two reasons why the brake fluid level in
the reservoir 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 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.
If you have too much brake fluid, it can spill on
the engine. The fluid
will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fl~~id ~n!y when work is done on the brake
hydraulic system.

BRAKE
United States Canada
When your brake fluid falls to a low level, your brake
warning light will come on. See
Brake System Warning
Light on page
3-26.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container
only. See
Part D: Recommended Fluids and Lubricants
on page
6- 15.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
With the wrong kind of fluid in your brake
system, your brakes may not work well, or
they may not even work at all. This could
cause
a crash. Always use the proper brake
fluid.
Notice:
Using the wrong fluid can badly damage brake
system parts. 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.
Don’t let someone put in the wrong kind of fluid.
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can be damaged. Be
careful not to spill brake fluid on your vehicle.
If you do, wash it off immediately. See
“Appearance Care” in the Index.

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.
Replacing Brake System Parts
The braking system on a 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. Your
vehicle was designed and tested with top-quality
GM
brake parts. When you replace parts of your braking
system
- for example, when your brake linings
wear down and you need new ones put in
- be sure you
get new approved 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
Your new vehicle comes with a maintenance free
ACDelco@ battery. When it’s time for a new battery, get
one that has the replacement number shown
on the
original battery’s label. We recommend an ACDelco@
battery. See
Engine Compartment Overview on
page
5- 12 for battery location.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known
to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.

1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other system isn’t a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able
to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.
Notice: If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn
off the radio and all lamps that aren’t
needed. This will avoid sparks and help save
both batteries. And it could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative
(-) terminal locations on
each vehicle. See
Engine Compartment Overview
on page
5-12 for more information on location.

An electric fan can start up even when the
engine
is not running and can injure you. Keep
hands, clothing and tools away from any
underhood electric fan.

Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water. You
don’t need to add water to the ACDelco@
battery installed in your new vehicle. But if a
battery has filler caps, be sure
the right
amount of fluid is there. If
it is low, add water
to take care of that first. If you don’t, explosive
gas could be present.
Battery fluid contains acid that can burn you.
Don’t get it on you. If you accidentally get
it in
your eyes or on your skin, flush the place with
water and get medical help immediately. Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts
once the engine is running.
5. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive
(+) will go to
positive
(+) or to a remote positive (+) terminal if
the vehicle has one. Negative (-) will go to a heavy,
unpainted metal engine part or to a remote
negative
(-) terminal if the vehicle with the dead
battery has one.
Don’t connect positive
(+) to negative (-) or you’ll
qet a short that would damage the battery and
maybe other parts, too. And don’t connect
the negative
(-) cable to the negative (-) terminal
on the dead battery because this can cause sparks.
