Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag system in several places
around your vehicle. You don’t want the system to
inflate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see
Service Publications
Ordering Information
on page 7- 10.
For up tc .D minutes after the igniti,.i key is
turned
off and the battery is disconnected, an
air bag can still inflate during improper
service. You can be injured if you are close to
an air bag when
it inflates. Avoid wires
wrapped with yellow tape or yellow connectors. They are probably part of the air
bag system. Be sure to follow proper service
procedures, and make sure the person
performing work for you
is qualified to do so.
The air bag system does not need regular maintenance.
1-59

Restraint System Check
Checking Your Restraint Systems
Now and then, 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.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces.
If a belt
is torn or frayed, get
a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Replacing Restraint System Parts
After a Crash
A crash can damage the restrain1 (stems in
your vehicle.
A damaged restraint system may
not properly protect the person using
it,
resulting in serious injury or even death in a
crash.
To help make sure your restraint
systems are working properly after
a crash,
have them inspected and any necessary
replacements made as soon as possible.
1-60

This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or
CHECK
ENGINE light comes on to indicate that there is a
problem and service is required. Malfunctions often will
be indicated by the system before any problem is
apparent. This may prevent more serious damage to
your vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.
Notices If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notices Modifications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come
on.
Modifications to these systems could lead to costly
repairs not covered by your warranty. This may
also result
in a failure to pass a required Emission
Inspection/Maintenance test. This light should
come on, as a check to show you it is
working, when the ignition is on and the engine is
not running.
If the light doesn’t come on, have it
repaired. This light will also come on during a
malfunction
in one of two ways:
Light Flashing - A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
Light On Steady - An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis
and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady’’ following.
3-32

If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart
the engine.
If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
flashing, follow the previous steps, and drive the vehicle
to your dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See
Filling Your Tank on page 5-7. The
diagnostic system can determine
if the fuel cap has
been left off or improperly installed.
A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light
off.
Did you just drive through a deep puddle of water?
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel. See
cause your engine not to run as efficiently as designed.

when you put the vehicle into gear, misfiring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check
the vehicle. Your dealer has the proper test equipment
and diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your \.lehic!e wi!! not pass this inspectinn if the SERV!CE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
3-33

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you find them quickly. If you’re trailering,
it’s a good idea to review this information before you
start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See
Engine Overheating on
page
5-26.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to use the proper service manual. It tells you
much more about how to service your vehicle than this
manual can. To order the proper service manual,
see
Service Publications Ordering Information on
page
7- 10.
Your vehicle has an air bag system. Before attempting
to do your own service work, see
Servicing Your Air
Bag-Equipped Vehicle on page 1-59.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See
Part E: Maintenance Record on page 6- 16.
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about
it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you
use the wrong fasteners, parts can later
break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside
of your vehicle.
5-4

Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use regular unleaded gasoline with a posted octane
of
87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive.
If this
occurs, use a gasoline rated at
87 octane or higher as
soon as possible. Otherwise, you might damage
your engine.
A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary.
If you are using 87 octane or higher-octane
fuel and hear heavy knocking, your engine needs
service.
Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.

Engine Air Cleaner/Filter 3. Check or replace the engine air cleaner/filter.
4. Put the cover back on tightly.
2.2L L4 ECOTEC Engine shown,
3400
V6 Engine similar
The engine air cleanedfilter is located in the engine
compartment on the driver’s side
of the vehicle.
See
Engine Compartment Overview on page 5- i2 ior
more information on location.
To check or replace the engine air cleaner/filter, do the
following:
1. Remove the screws that hold the cover on.
2. Lift off the cover. Refer
to the Maintenance Schedule to determine when
to replace the air filter.
See
Part A: Scheduled Maintenance Services on
page
6-4.
I--
Operating the engine with the air cleaner/filter
off can cause you or others to be burned. The
air cleaner not only cleans the air,
it stops
flame if the engine backfires.
If it isn’t there
and the engine backfires, you could be burned. Don’t drive with
it off, and be careful working
i on the engine with the air cleanerlfilter off.
Notice; If the air cleanerlfilter is off, a backfire can
cause a damaging engine fire. And, dirt can
easily get into your engine, which will damage
it.
Always have the air cleaner/filter in place when
you’re driving.
