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.

for more information.
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

additional maintenance is
recommended in the Maintenance
Schedule in this manual.
SeeScheduled Maintenance on
page 10-2for more information.
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.
8-2 Driving and Operating

What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
filter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer/retailer service department
and have it repaired as soon as
possible.
There is a special procedure
for checking and changing the
transmission fluid. Because this
procedure is difficult, you should
have this done at your dealer/
retailer service department.Contact your dealer/retailer for
additional information or the
procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
on page 12-12.
Change the fluid and filter at the
intervals listed inScheduled
Maintenance on page 10-2, and
be sure to use the fluid listed
inRecommended Fluids and
Lubricants on page 10-7.
9-14 Vehicle Care

Park on a fairly steep hill, with the
vehicle facing downhill. Keeping
your foot on the regular brake,
set the parking brake.
•To check the parking brake’s
holding ability: With the engine
running and the transmission
in N (Neutral), slowly remove
foot pressure from the regular
brake pedal. Do this until
the vehicle is held by the
parking brake only.
•To check the P (Park)
mechanism’s holding ability:
With the engine running, shift
to P (Park). Then release the
parking brake followed by the
regular brake.
Contact your dealer/retailer if
service is required.
Wiper Blade
Replacement
Windshield wiper blades should be
inspected for wear and cracking.
SeeScheduled Maintenance on
page 10-2for more information.
Replacement blades come in
different types and are removed
in different ways. For proper type
and length, seeMaintenance
Replacement Parts on page 10-9.To replace the windshield wiper
blade:
1. Pull the windshield wiper
assembly away from the
windshield.
2. Lift up on the latch in the middle
of the wiper blade where the
wiper arm attaches.
