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
in¯ate 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 7-11.
{CAUTION:
For up to 10 seconds after the vehicle 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 wires,
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 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.)

«9ª(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the air¯ow seems low when the fan speed is at
the highest setting, the passenger compartment air ®lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-38andScheduled Maintenance on page 6-4.
ªN«(Mode):Pressing the switch and changing the

system in manual mode. Press the AUTO button to
return to automatic operation.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the ¯oor outlets. In
automatic operation, cooler air is directed to the
upper outlets and warmer air to the ¯oor outlets.
6(Floor):This mode directs most of the air to the
¯oor outlets with some air directed to the side window
outlets, and a little air directed to the windshield.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.

is turned off.
3-35

Outlet Adjustment
Use the thumbwheel to open or close the outlets.
Operation Tips
·
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ¯ow of air into your vehicle.
·Use of non-GM approved hood de¯ectors may
adversely affect the performance of the system.
·Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air ®lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in air¯ow, which may occur
more often in dusty areas, indicate that the ®lter may
need to be replaced early.
The ®lter should be replaced as part of the routine
scheduled maintenance. See
Scheduled Maintenance
on page 6-4for more information.
The passenger compartment air ®lter is located on the
passenger's side of the engine compartment near
the battery. See
Engine Compartment Overview on
page 5-12for more information on location.
To check or replace the air ®lter, do the following:
1. With the hood open, unlatch and remove the access
panel.
2. Pull the old ®lter out of the housing.
3. Insert the new ®lter into the housing. The ®lter
should be fully inserted with the arrows pointing up.
4. Reinstall the air ®lter access panel.

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,
transmission, 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.
This light should come on brie¯y, as a check to show
you it is working, as you start the engine. 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 FlashingÐ A mis®re condition has
been detected. A mis®re increases vehicle
emissions and may damage the emission control
system on your vehicle. Diagnosis and service may
be required.
·Light On SteadyÐ 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 the light stops ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to ¯ash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the engine off, wait at least 10 seconds and
restart the engine. If the light remains on steady, see ªIf
the Light Is On Steadyº following. If the light is still
¯ashing, follow the previous steps, and see your dealer
for service as soon as possible.
3-49

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.
3-51

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa). In
certain situations such as long, extended idles on
hot days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. See
DIC Warnings and
Messages on page 3-57andEngine Oil on page 5-13.
{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 OIL NOW:This means that the life of the
engine oil has expired. SeeScheduled Maintenance on
page 6-4. After an oil change, the Oil Life Indicator
must be reset. SeeOil Life Indicator on page 3-70. SeeEngine Oil on page 5-13.
CHARGE SYSTEM FAULT:This message will display
when a problem with the charging system has been
detected. Have your vehicle serviced at your dealership.
CHECK GAS CAP:This message will appear if the
gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.
CLEAN RADAR CRUISE:This message indicates the
ACC system is disabled because the radar is blocked
and cannot detect vehicles in your path. It may
also activate during heavy rain or due to road spray. To
clean the system, see ªAdaptive Cruise Control
(ACC)º under
Turn Signal/Multifunction Lever on
page 3-5.
CLOSE CARGO COVER:This message indicates that
the cargo cover is not in place. Open the trunk and
make sure the cargo cover is secure and no objects are
on the cover. See
Rear Storage Area on page 2-43for more information.COOLANT OVER TEMP:This message will appear
when the engine coolant temperature is too hot.
Stop and allow your vehicle to idle in PARK (P) until it
cools down and the message is removed. Do not
increase engine speed above a normal idle. If it does
not cool down, turn off the engine and have it serviced
before driving it again. Severe engine damage can
result from an overheated engine. See
Engine
Overheating on page 5-23.
CRUISE NOT READY:This message indicates that
ACC will not activate due to a temporary condition. Your
vehicle does not require service. If this message
appears when you attempt to activate the system,
continue driving for several minutes then try again to
activate the system.
DRIVER NO. X (1 OR 2):This message will be
displayed when the vehicle is started or when there is a
change of driver. The message will show which driver
is activating the personalization feature. It will only
stay on for ®ve seconds.
ENGINE HOT, STOP ENGINE:This message will
appear when the engine has overheated. Stop and turn
the engine off immediately to avoid severe engine
damage. See
Engine Overheating on page 5-23.A
multiple chime will also sound when this message
is displayed.
3-58

Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It is based on the engine oil temperatures and
your driving patterns.
To see the display, press the information button several
times until OIL LIFE appears. If you see 99% OIL
LIFE, 99 percent of your current oil life remains.
The DIC may display a CHANGE OIL NOW message.
For more information, see
Scheduled Maintenance
on page 6-4. If you see CHANGE OIL NOW, it means
the oil life is gone and you should change the oil
right away. The system does not check how much oil
you have, so you will still have to check for that. To see
how, see
Engine Oil on page 5-13.
When the oil is changed, you will need to reset the
system. See
Engine Oil on page 5-13. Always keep a
written record of the mileage and date when you
changed your oil.
Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle's engine, radio, or other systems,
and even damage them. Your vehicle's systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, ®nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See
ªRetained Accessory Power (RAP)º under
Ignition
Positions on page 2-19.
