5. Then replace the pressure cap. Be sure the cap is
fully installed.
If the LOW COOLANT message does not appear on the
Driver Information Center (DIC) after two minutes, the
coolant is at the proper ll level. If a LOW COOLANT
message does appear, repeat Steps 1 through 3
then reinstall the pressure cap, or see your dealer.
Power Steering Fluid
SeeEngine Compartment
Overview on page 6-12for
reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A uid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the uid level on
the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough uid to bring the level up to
the mark.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 7-11.
Always use the proper uid. Failure to use the proper
uid can cause leaks and damage hoses and seals.
6-31

Windshield Washer Fluid
What to Use
When you need windshield washer uid, 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 uid that has
sufficient protection against freezing.
Adding Washer Fluid
The LOW WASHER FLUID message will be displayed
on the Driver Information Center (DIC) when the
uid is low.
Open the cap with the
washer symbol on it. Add
washer uid until the
tank is full. SeeEngine
Compartment Overview on
page 6-12for 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.

Maintenance Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
(a)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.
(b)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(c)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.)(d)Lubricate the trunk key lock cylinder. Lubricate all
body door hinges. Lubricate all hinges and latches,
including those for the hood, trunk, console door and
any 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.
(e)If you drive regularly under dusty conditions, the
lter may require replacement more often.
(f)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.
Uses such as high performance operation.
(g)Drain, ush and rell cooling system. See Engine
Coolant on page 6-20for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ller neck.
Pressure test the cooling system and pressure cap.
(h)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.

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

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 7-11.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel ll.
Engine Oil Level Check

necessary. SeeEngine Oil on page 6-13for further
details.
Notice:It is important to check your oil regularly
and keep it at the proper level. Failure to keep your
engine oil at the proper level can cause damage
to your engine not covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. SeeEngine
Coolant on page 6-20for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in the windshield
washer tank and add the proper uid if necessary.
At Least Once a Month
Tire Inspection and Ination Check
Visually inspect your tires for wear and make sure tires
are inated to the correct pressures. SeeTires on
page 6-46for further details.

Recommended Fluids and
Lubricants
Fluids and lubricants identied below by name, part
number or specication may be obtained from
your dealer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identied as
synthetic, and should also be
identied with the American
Petroleum Institute Certied for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. You should look
for and use only an oil that meets
GM Standard GM4718M. GM
Goodwrench oil meets all the
requirements for your vehicle. For
the proper viscosity, seeEngine Oil
on page 6-13.
