NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, or the air bag
covering on the driver's and right front
passenger's seatback, or the side impact air bag
covering on the ceiling near the side windows, the
bag may not work properly. You may have to
replace the air bag module in the steering wheel,
both the air bag module and the instrument
panel for the right front passenger's air bag, the
air bag module and seatback for the driver's and
right front passenger's seat

Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
air bag systems. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape,
yellow coverings or yellow connectors. They are
probably part of the air bag systems. Be sure to
follow proper service procedures, and make sure
the person performing work for you is qualified
to do so.
The air bag systems do not need regular maintenance.

Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
(Lock): When you press
this symbol on the remote
keyless entry transmitter,
the doors on the vehicle will
lock. This also arms the
theft
-deterrent system.
You can program your vehicle so that the exterior lamps
will flash and/or the horn will sound when you lock the
doors with the remote keyless entry transmitter. See
ªVehicle Programming and Personalization Featuresº
in the Index for more information on programming
this feature.
If your vehicle is programmed for remote confirmation,
the doors must be closed for this feature to work. If a
door is open, remote confirmation will be canceled.

2-13
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.
1. Use a flat thin object to pry open the transmitter.
2. Once the transmitter is separated, use a pencil or
similar object to remove the old battery. Do not use
a metal object.

2-14
3. Insert the new battery as the instructions under the
cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press any button on the remote keyless entry
transmitter to resynchronize the transmitter.
6. Check the operation of the transmitter.
Reconfigurable Steering Wheel
Controls (SWC)
This feature allows you to customize the four steering
wheel controls to work with the OnStar
, the climate
control, audio and traction control systems.
The controls for this feature
are located on the left spoke
of the steering wheel.
To program one of these controls, use one of the
following procedures:
If your vehicle is equipped with the Base audio system,
do the following:
1. Access the main menu of the audio system by
pressing the TUNE/SEL knob located at the lower
right of the audio system.

Steering Column Ignition Lock Release
(Automatic Transmission Only)
If your vehicle has a dead battery or a battery with low
voltage, you can still release the ignition lock and
remove the key. Use the following procedure to release
the shift lever:
1. Locate the plastic screw head on the underside of the
plastic cover for the steering column.
2. Insert a flat, thin object into the slot and turn it
until the plastic piece detaches from the steering
column cover.
3. Insert a narrow, pointed object into the hole in the
steering column cover and press the spring.
4. Then, turn the ignition switch to OFF and remove
the key.

SECOND (2): This position gives you even more
power than THIRD (3). You can use it on very steep
hills, or in deep snow or mud. (If the shift lever is put
in SECOND (2), the transmission won't shift into
SECOND (2) until the vehicle is going slowly enough).
NOTICE:
If the vehicle's wheels can't turn, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could cause overheating and damage
the transmission. Use your brakes to hold your
vehicle in position on a hill.
Shift Lock Release
(Automatic Transmission Only)
If your vehicle has a dead battery or a battery with low
voltage, you can still shift the vehicle into PARK (P) and
remove the ignition key. Use the following procedure to
release the shift lever:
1. Pull up on the rear part of the leather boot that
surrounds the shift lever.
2. Fold the boot upward to expose the mechanism
beneath the shift lever.

CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
If there is a problem with the air bag system in your
vehicle, the Service Air Bag message will appear on the
DIC display. See ªService Air Bag Messageº later in
this section for more information.
Charging System Light
When you turn the key to
ON or START, this light
will come on briefly to
show that the generator and
battery charging systems are
working properly.
If this light stays on, your vehicle needs service. You
should take your vehicle to the dealer at once. To save
your battery until you get there, turn off all accessories.

6-34 Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top
-quality GM brake parts.
When you replace parts of your braking system
-- for
example, when your brake linings wear down and you
need new ones put in
-- be sure you get new approved
GM replacement parts. If you don't, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change
-- for the
worse. The braking performance you've come to expect
can change in many other ways if someone puts in the
wrong replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See ªEngine Compartment Overviewº in the
Index for battery location.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
After a power loss, such as disconnecting the battery or
removing the maxi fuses in the power distribution fuse
block, the following steps must be performed to
calibrate the electronic throttle control. If this is not
done, the engine will not run properly.
1. Turn the ignition key to ON. Do not start the engine.
2. Leave the ignition in ON for at least three minutes so
that the electronic throttle control will cycle and
re
-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least 30 seconds.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
