Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the air
bag systems. To purchase a service manual, see
Service
Publications Ordering Information on page 7-12.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
air bag can still in¯ate during improper service.
You can be injured if you are close to an air bag
when it in¯ates. Avoid 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 quali®ed to do so.
The air bag systems do not need regular maintenance.
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.)

For more information on how to use the main climate
control system, see ªClimate Control Systemº listed
previously in this section. For information on ventilation,
see ªOutlet Adjustmentº under ªClimate Control
Systemº listed previously in this section.
Passenger Compartment Air Filter
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment ®lter. The ®lter removes certain
contaminants from the air, including pollen and dust
particles. Reductions in air¯ow, which may occur more
quickly in dusty areas, indicate that the ®lter needs
to be replaced early. For how often to change the air
®lter, see
Scheduled Maintenance on page 6-4.
The access panel for the passenger compartment air
®lter is located in the back of the glove box. To replace
the ®lter, do the following:1. Pull the tab located on the outer access panel
up and out.
3-39

2. Then push the tab, located on the left of the inner
access panel, to the right.3. The ®rst air ®lter will pull straight out. To remove
the second, reach in and slide it toward the
opening. Pull the second ®lter out.
4. Replace the ®lters by reversing Step 3. Make sure
the ®lters are inserted so that the sealing foam is
angled in the same direction on both ®lters. For the
type of ®lter to use, see
Normal Maintenance
Replacement Parts on page 6-14.
5. Close the inner access door, while squeezing the
tab. Be sure it is tightly closed.
6. Snap the outer access panel into the back of the
glove box.

Malfunction Indicator Lamp
Service Engine Soon Light in the
United States or Check Engine Light
in Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (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.
Notice: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.
Notice:Modi®cations 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.
Modi®cations 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. United StatesCanada

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, mis®ring, 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,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x 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 vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

Message Center
The message center is located in the instrument panel
cluster. It gives you important safety and maintenance
facts.
Service Traction System Warning
Message
If your vehicle has the traction control system and this
message is displayed when you're driving, there may be
a problem with your traction control system. Your vehicle
may need service.When this message is displayed, the traction control
system will not limit wheel spin. Adjust your driving
accordingly.
The message may appear for the following reasons:
·If there's a brake system problem that is speci®cally
related to traction control, the traction control
system will turn off and the warning message will
come on.
·If your brakes begin to overheat, the traction control
system will turn off and the warning message will
come on until your brakes cool down.
·If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning message will come on.
If the traction control system warning message comes
on and stays on for an extended period of time when the
system is turned on, your vehicle needs service. United States
Canada
3-53

When the engine is running and this message appears,
the engine oil level may be too low. There may also
be another problem causing low oil pressure.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
Change Engine Oil Message
If this message comes on and stays on after you started
the engine, have the oil changed.
For additional information on when to change the oil
and resetting the system, see
Engine Oil on page 5-13. United States
Canada

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.
·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 are
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle ¯uid, engine oil, belts,
cooling system and brake system. Each of these is
covered in this manual, and the Index will help you ®nd
them quickly. If you are trailering, it is a good idea to
review these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
Your vehicle has a trailer wiring harness located at the
rear of your vehicle. To use the trailer wiring harness
you need a converter kit. Contact your dealer for more
information.
