1-12 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.

If it says AIR BAG on the middle part of the steering
wheel and AIR BAG on the instrument panel in front of
the right front passenger's seat, your vehicle has two air
bags
-- one air bag for the driver and another air bag for
the right front passenger.If it says AIR BAG on the middle part of the steering
wheel but it doesn't say AIR BAG on the instrument
panel in front of the right front passenger's seat, your
vehicle has an air bag for the driver only.
If it says AIR BAG on the middle part of the steering
wheel, but there is no right front passenger seat,
your vehicle has an air bag for the driver only.
If it doesn't say AIR BAG on the middle part of the
steering wheel, your vehicle doesn't have air bags.
Frontal air bags are designed to help reduce the risk of
injury from the force of an inflating air bag. But these
air bags must inflate very quickly to do their job and
comply with federal regulations.

1-29 How the Air Bag System Works
Where are the air bags?
The driver's air bag is in the middle of the steering wheel.
The right front passenger's air bag is in the instrument
panel on the passenger's side.

1-30
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.
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
-frontal crash. The air bag will 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 16 mph (14 to 26 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 air bag is not designed to inflate in rollovers, rear
impacts, or in many side 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.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near
-frontal impacts.

1-31
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. 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 and in the instrument panel in front of
the right front passenger.
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. Air bags supplement 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 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
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.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, or the instrument panel for the right front
passenger's 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 vents in the deflated
air bags. Air bag inflation doesn't prevent the driver
from seeing or from 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 door.

Air bags are designed to inflate only once. After they
inflate, 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 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
system. Improper service can mean that your 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, the bag may
not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for the
right front passenger's air bag. Do not open or
break the air bag coverings.

The rear swing

side swing out windows, but the latch is located at the
bottom edge of the window. See ºSide

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. Also remember to lock
the doors.
