1-8 Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Take the simplest vehicle. Suppose it's just a seat
on wheels.
Put someone on it.

1-24 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.

1-25
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.
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 and don't let seat covers block
the inflation path of a side impact air bag.

1-26
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,
side impacts, or rear 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.
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.

1-27
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. 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.

1-28
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.
