{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system in
several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer and the
service manual have information about servicing
your vehicle and the airbag system. To purchase a
service manual, seeService Publications
Ordering Information on page 544.
{CAUTION:
For up to 10 seconds after the ignition
key is turned off and the battery is
disconnected, an airbag can still inate
during improper service. You can be
injured if you are close to an airbag when
it inates. Avoid yellow connectors. They
are probably part of the airbag system. Be
sure to follow proper service procedures,
and make sure the person performing
work for you is qualied to do so.
The airbag system does not need regular
maintenance.

Restraint System Check
Checking the 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. SeeCare of Safety Belts on page 490.
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 airbag covers,
and have them repaired or replaced. The airbag
system does not need regular maintenance.Notice:If you damage the covering for the
driver’s or the right front passenger’s frontal
airbag, or an airbag covering (if equipped) on a
seatback, the airbag may not work properly.
You may have to replace the airbag module in
the steering wheel, both the airbag module and
the instrument panel for the right front
passenger’s frontal airbag, or both the airbag
module and the seatback for seating positions
with a side impact airbag (if equipped.) Do not
open or break the airbag coverings.
93

Rear Air Outlets
The outlet behind the left rear seat is the cold
air return outlet. Be sure to keep it free from
obstructions. Also, keep the area around the base
of the center instrument panel console, between
and under the front seats, free of objects that could
also obstruct airow to the rear seating area.
For more information on how to use the main
climate control system, seeDual Climate Control
System on page 197. For information on
ventilation, seeOutlet Adjustment on page 200.
Passenger Compartment Air Filter
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment lter. The lter removes most
particles from the air, including dust particles.
Reductions in airow, 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, seeScheduled Maintenance
on page 509.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.
205

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 520.
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.
206

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 awhile, 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:Modications 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. Modications 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. SeeAccessories
and Modifications on page 400.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 does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. 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

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 to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
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.
Oil Pressure Light
If your vehicle has low
engine oil pressure, this
light will stay on after
you start your engine,
or come on when
you are driving.
This indicates that your engine is not receiving
enough oil. The engine could be low on oil,
or could have some other oil problem. Have it
xed immediately by your dealer.
The oil light could also come on in three other
situations:
When the ignition is on but the engine is not
running, the light will come on as a test to show
you it is working. The light will go out when you
turn the ignition on. If it does not come on with
the ignition on, you may have a problem with
the fuse or bulb. Have it xed right away.
If you are idling at a stop sign, the light may
blink on and then off.
If you make a hard stop, the light may come on
for a moment. This is normal.
220

{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.
Security Light
For information
regarding this light,
seeTheft-Deterrent
Systems on page 123.
Cruise Control Light
This light comes on
whenever you set
your cruise control.
The light will go out when the cruise control is
turned off. SeeCruise Control on page 177
for more information.
Highbeam On Light
This light will come on
when the high-beam
headlamps or the
Flash-to-Pass feature
is in use.
SeeHeadlamp High/Low-Beam Changer on
page 174.
