In addition, your dealer/retailer and
the service manual have information
about the location of the airbag
sensors, sensing and diagnostic
module and airbag wiring.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance
or replacement. Make sure the
airbag readiness light is working.
SeeAirbag Readiness Light on
page 4-17for more information.
Notice:If an airbag covering is
damaged, opened, or broken, the
airbag may not work properly.
Do not open or break the airbag
coverings. If there are any opened
or broken airbag covers, have the
airbag covering and/or airbag
module replaced. For the location
of the airbag modules, seeWhat
Makes an Airbag Inflate? on
page 2-26. See your dealer/retailer
for service.
Replacing Airbag System
Parts After a Crash
{WARNING
A crash can damage the
airbag systems in your vehicle.
A damaged airbag system may not
work properly and may not protect
you and your passenger(s) in a
crash, resulting in serious injury or
even death. To help make sure
your airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.If an airbag inflates, you will need
to replace airbag system parts.
See your dealer/retailer for service.
If the airbag readiness light stays
on after the vehicle is started
or comes on when you are driving,
the airbag system may not work
properly. Have the vehicle serviced
right away. SeeAirbag Readiness
Light on page 4-17for more
information.

SeeEngine Oil Messages on
page 4-32andEngine Oil on
page 9-10for more information.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned.
Check the oil as soon as possible
and have the vehicle serviced.
Notice:Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
A reading in the low pressure zone
can be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check
the oil as soon as possible.
Engine Oil
Temperature Gage
This gage, located in front of the
shifter, shows the engine oil
temperature.
If the gage pointer moves into the
red area, it means that the engine oil
has overheated. If the vehicle has
been operated under normal driving
conditions, pull off the road, stop
the vehicle and turn off the engine
as soon as possible.

When the Light is On Steady
This indicates that one or more of the
tires are significantly underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. SeeTire
Messages on page 4-36for more
information. Stop and check the tires
as soon as it is safe to do so.
If underinflated, inflate to the proper
pressure. SeeTire Pressure on
page 9-54for more information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.

come on briefly as the engine is
started. If it does not come on
have the vehicle serviced by your
dealer/retailer.
If the light comes on and stays on,
it means that oil is not flowing
through the engine properly.
The vehicle could be low on oil and
might have some other system
problem. See your dealer/retailer.

Remaining Oil Life
This display shows an estimate
of the oil’s remaining useful life.
If Remaining Oil Life 99% is
displayed, that means 99% of
the current oil life remains.When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the
display. SeeEngine Oil Messages
on page 4-32. The oil should
changed as soon as possible.
SeeEngine Oil on page 9-10.
In addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended in the Maintenance

Remember, the Oil Life display
must be reset after each oil change.
It will not reset itself. Also, be

4-32 Instruments and Controls
Passenger Compartment
Air Filter
The passenger compartment air
filter removes most of the pollen
and dust from the air that enters
the vehicle. The filter will need
to be replaced periodically.
SeeScheduled Maintenance on
page 10-2.
Using the climate control system
without an air filter installed is
not recommended. Water or other
debris could enter the system
and result in leaks or noises.
Always install a new filter when
removing the old filter.
Air Vents
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airflow. Use the thumbwheels
near the center air outlets to
direct airflow to the left or right.
Operation Tips
•In defog or defrost mode, warm
air flows from the some air
outlets. To improve side window
defogging or defrosting, direct
side air outlets towards the side
windows.
•Clear away any ice, snow, or
leaves from air inlets at the
base of the windshield that
could block the flow of air into
the vehicle.
•Keep the path under the front
seats clear of objects to help
circulate the air inside of
the vehicle more effectively.
•Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer/retailer
before adding equipment to
the outside of the vehicle.

Driving Information
Driving for Better
Fuel Economy
Driving habits can affect fuel
mileage. Here are some driving tips
to get the best fuel economy
possible.
•Avoid fast starts and accelerate
smoothly.
•Brake gradually and avoid abrupt
stops.
•Avoid idling the engine for long
periods of time.
•When road and weather
conditions are appropriate,
use cruise control, if equipped.
•Always follow posted speed limits
or drive more slowly when
conditions require.
•Keep vehicle tires properly
inflated.
•Combine several trips into a
single trip.
•Replace the vehicle’s tires with
the same TPC Spec number
molded into the tire’s sidewall
near the size.
•Follow recommended scheduled
maintenance.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
your safety belt, seeSafety Belts on
page 2-6.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
•Allow enough following
distance between you and
the driver in front of you.
•Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
