1-23 How the Air Bag Systems Work
Where are the air bags?
The driver's frontal air bag is in the middle of the
steering wheel.
The right front passenger's frontal air bag is in the
instrument panel on the passenger's side.

1-24
The driver's side impact air bag is in the side of the
driver's seatback closest to the door.
CAUTION:
If something is between an occupant and an
air bag, the bag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating air bag must be kept clear. Don't put
anything between an occupant and an air bag,
and don't attach or put anything on the
steering wheel hub or on or near any other
air bag covering. Don't let seat covers block
the inflation path of a side impact air bag.

1-25
When should an air bag inflate?
The driver's and right front passenger's frontal air bags
are designed to inflate in moderate to severe frontal or
near
-frontal crashes. But they are designed to inflate
only if the impact speed is above the system's designed
ªthreshold level.º
If your vehicle goes straight into a wall that doesn't move
or deform, the threshold level is about 12 to 18 mph
(19 to 29 km/h). The threshold level can vary, however,
with specific vehicle design, so that it can be somewhat
above or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The driver's and right front passenger's frontal
air bags are not designed to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
The driver's side impact air bag is designed to inflate in
moderate to severe side crashes involving the driver's
door. The side impact air bag will inflate if the crash
severity is above the system's designed ªthreshold
level.º The threshold level can vary with specific
vehicle design.The driver's side impact air bag is not designed to
inflate in frontal or near
-frontal impacts, rollovers
or rear impacts, because inflation would not help
the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near
-frontal impacts. For the side impact
air bag, inflation is determined by the location and
severity of the impact.
What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact air bags, the sensing system
triggers a release of gas from the inflator, which inflates
the air bag. The inflator, air bag and related hardware
are all part of the air bag modules inside the steering
wheel, instrument panel and the side of the driver's
seatback closest to the door.

1-26
How does an air bag restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But the frontal
air bags would not help you in many types of collisions,
including rollovers, rear impacts, and many side
impacts, primarily because an occupant's motion is not
toward the air bag. The side impact air bag would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear impacts,
primarily because the occupant's motion is not toward
that air bag. Air bags should never be regarded as
anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near
-frontal
collisions for the driver's and right front passenger's
frontal air bags, and only in moderate to severe side
collisions for the driver's side impact air bag.What will you see after an air bag inflates?
After an air bag inflates, it quickly deflates, so quickly
that some people may not even realize the air bag
inflated. Some components of the air bag module
-- the
steering wheel hub for the driver's air bag, the
instrument panel for the right front passenger's bag, the
side of the seatback closest to the door for the driver's
side impact air bag
-- will be hot for a short time. The
parts of the bag that come into contact with you may be
warm, but not too hot to touch. There will be some
smoke and dust coming from the vents in the deflated
air bags. Air bag inflation doesn't prevent the driver
from seeing or being able to steer the vehicle, nor does
it stop people from leaving the vehicle.
CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.

1-27
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the frontal air bag system. The module records
information about the readiness of the system, when
the system commands air bag inflation and driver's
safety belt usage at deployment. The module also
records speed, engine rpm, brake and throttle data.
Let only qualified technicians work on your air
bag systems. Improper service can mean that an
air bag system won't work properly. See your dealer
for service.
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 seatback, 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, or the air
bag module and seatback for the driver's side
impact air bag. Do not open or break the air
bag coverings.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your trunk
or glove box.

Be sure to close and lock the storage area.

Close all windows.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

2-24
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in
the long run if you follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
With the ignition key in the ignition, you can turn the
key to five different positions:
A (ACCESSORY): This position lets you use the
radio and windshield wipers when the engine is off. To
use ACCESSORY, push in the key and turn it toward
you. Your steering wheel will stay locked.

2-25
B (LOCK): This is the only position in which you
can insert or remove the key. This position locks the
ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.D (RUN): This position is where the key returns to
after you start your vehicle. With the engine off, you
can use RUN to display some of your warning and
indicator lights.
E (START): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition.
Retained Accessory Power (RAP)
(If Equipped)
With Retained Accessory Power (RAP), your
power windows, audio system and sunroof (if equipped)
will continue to work for up to 10 minutes after the
ignition key is turned to OFF and before any of the
doors are opened.

2-37
CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.
Horn
Press the horn symbol on your steering wheel pad to
sound the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever.
Then move the steering
wheel to a comfortable
position and release the
lever to lock the wheel
into place.

2-58
(Volume Control): You can control the volume
of the OnStar System using either the volume knob
on the radio or using the steering wheel volume control
(If equipped).
(Telltale Light): This light will indicate the status of
the system. A solid green light will come on when you
start the vehicle to let you know that the system is on
and is ready to make or receive calls.
If the light blinks green it means that an incoming or
outgoing call is in progress. Press the Communication
button if you notice the light blinking and you are not
on a call.
The light will be red in the event of an OnStar system
malfunction. If this occurs press the OnStar button to
attempt to contact an advisor. If the connection is made,
the advisor will assist you with steps to take to make
sure that the system is functioning properly. If you
cannot contact the advisor, take your vehicle to your
dealership as soon as possible for assistance.
Cellular Antenna
The cellular antenna on the outside of your vehicle is
critical to effective communications using the OnStar
system. Optimum cellular reception can be obtained
when the mast is straight up and down.
OnStar Services
The following services are available within OnStar
service plans. Your vehicle comes with a specific
one
-year service plan that allows use of some or all for
the following services.

Automatic Notification of Air Bag Deployment: If
an air bag deploys, a priority emergency signal is
automatically sent to the center. An advisor will
locate your vehicle's position, try to contact you
and assist you in the situation. If the center is unable
to contact you, an emergency service provider will
be contacted.
