{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.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 556.

If your vehicle has the built-in child restraint, torn
or frayed harness straps can rip apart under
impact forces just like torn or frayed safety belts
can. They may not protect a child in a crash.
If a harness strap is torn or frayed, get a
new harness 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.Replacing Restraint System Parts
After a Crash
{CAUTION:
A crash can damage the restraint systems
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.
If you have had a crash, do you need new safety
belts or built-in child restraint parts or LATCH
system parts?
After a very minor collision, nothing may be
necessary. But if the safety belts or built-in child
restraint harness straps were stretched, as
they would be if worn during a more severe crash,
then you need new parts.

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 220. For information on
ventilation, seeOutlet Adjustment on page 223.
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 539.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.
228

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 550.
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
Check Engine Light
Your vehicle has 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 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 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 426.

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.
{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.
