Adding Washer Fluid
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 366
for reservoir location.
Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions for
adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to freeze
and damage your washer uid tank and
other parts of the washer system. Also,
water does not clean as well as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 366for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.

(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(f)Lubricate all key lock cylinders, hood latch
assembly, secondary latch, pivots, spring anchor,
release pawl, rear compartment hinges, outer
liftgate handle pivot points, rear door detent link,
roller mechanism, liftgate handle pivot points, latch
bolt, fuel door hinge, cargo door hinge, locks,
and folding seat hardware. More frequent
lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)Inspect hoses for cracks, chang, leaks, kinks,
and proper installation.(h)Change automatic transmission uid and lter
if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 379 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and
repaired and the uid level checked. Add uid if
needed.

(k)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(l)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help ensure
the safety, dependability, and emission control
performance of your vehicle. Your GM
Goodwrench
®dealer can assist you with these

Be sure any necessary repairs are completed at
once. Whenever any uids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 489.
At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
