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 9 to 15 mph
(14 to 24 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,
side impacts, or rear impacts, because inflation would
not help the occupant.
The side impact air bags are designed to inflate in
moderate to severe side crashes. A 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. Side impact air bags are not designed to inflate in frontal
or near
-frontal impacts, rollovers or rear impacts,
because inflation would not help the occupant. A side
impact air bag will only deploy on the side of the
vehicle that is struck.
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 side impact air
bags, 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 front
seatbacks closest to the door.

1-32
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 side impacts,
primarily because an occupant's motion is not toward
the air bag. Side impact air bags would not help you in
many types of collisions, including frontal or near
frontal collisions, rollovers, and rear impacts, primarily
because an occupant's motion is not toward those air
bags. 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 and right front passenger's side impact air bags.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 and right front
passenger's side impact air bags
-- 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.

1-33
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.
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.

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 and right front
passenger'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 both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

2-16 Trunk Release Handle (If Equipped)
NOTICE:
The trunk release handle was not designed to be
used to tie down the trunk lid or as an anchor
point when securing items in the trunk. Improper
use of the trunk release handle could damage it.
There is a glow-in-the-dark trunk release handle located
inside the trunk near the latch. This handle will glow
following exposure to light. Pull the release handle up to
open the trunk from the inside.
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 tone 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 transmission. And remember to lock
the doors.

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
Keep in mind that you may have to turn the steering
wheel as you turn the key in order to turn the ignition
switch from LOCK to START
-- this is normal. Using
extra effort to remove the key from the ignition switch,
as compared to other GM vehicles that you may have
owned, is also normal.
If your key is stuck in the ignition switch and cannot be
turned back to LOCK, your vehicle will need to be
repaired. See your dealer for service.
With the key in the ignition switch, you can turn it to
four different positions.
LOCK (): This is the only
position from which you
can remove the key. This
position locks the ignition,
steering wheel and
transmission. It's a
theft
-deterrent feature.

2-21
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. But 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.
OFF (I): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
ON (II): This is the position used for driving
your vehicle.START (III): This position starts the engine.
To lock the steering column, remove the key while in
LOCK. Turn the steering wheel until you hear a click.
Retained Accessory Power (RAP)
The radio and the optional cellular phone are the only
accessories on your vehicle that may be used for up to
10 minutes after the ignition is turned to OFF or until a
door is opened.
Power to the door locks is available at all times.
Power to the fuel door and trunk release will be
available for 15 minutes after the ignition is turned
to OFF.
The power window controls and the sunroof (optional)
controls are active until a door is opened
-- there is no
time limit as long as the doors remain closed.

2-26
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply the regular
brakes before you can shift from PARK (P) when
the ignition key is in ON. If you cannot shift out of
PARK (P), ease pressure on the shift lever
-- push the
shift lever all the way into PARK (P) as you maintain
brake application. Then move the shift lever into the
gear you wish. See ªShifting Out of PARK (P)º in
this section.
REVERSE (R): Use this gear to back up.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging the transmission, see
ªStuck: In Sand, Mud, Ice or Snowº in the Index.
NEUTRAL (N): The engine doesn't connect with
the wheels when driving in NEUTRAL (N). Use
NEUTRAL (N) to restart your vehicle when you're
already moving or when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to the transmission caused by shifting
out of PARK (P) or NEUTRAL (N) with the
engine racing isn't covered by your warranty.
