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.

1-29 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 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.
Center Passenger Position
Lap Belt
If your vehicle has front and rear bench seats, someone
can sit in the center positions.

1-30
When you sit in a center seating position, you have a
lap safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. If the belt isn't long enough,
see ªSafety Belt Extenderº at the end of this section.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt quickly
if you ever had to.

1-31
Rear Seat Passengers
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger Positions
Lap-Shoulder Belt
The positions next to the windows have lap
-shoulder
belts. Here's how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
The shoulder belt may lock if you pull the belt across
you very quickly. If this happens, let the belt go back
slightly to unlock it. Then pull the belt across you
more slowly.

1-32
2. Push the latch plate into the buckle until it clicks.
If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle it.
Pull up on the latch plate to make sure it is secure.On some vehicles, when the shoulder belt is pulled
out all the way, it will lock. If it does, let it go back
all the way and start again. If the belt is not long
enough, see ªSafety Belt Extenderº at the end
of this section. Make sure the release button on
the buckle is positioned so you would be able to
unbuckle the safety belt quickly if you ever had to.
3. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder part.

1-33
The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this applies
force to the strong pelvic bones. And you'd be less likely
to slide under the lap belt. If you slid under it, the belt
would apply force at your abdomen. This could cause
serious or even fatal injuries. The shoulder belt should
go over the shoulder and across the chest. These parts
of the body are best able to take belt restraining forces.
The safety belt locks if there's a sudden stop or a crash,
or if you pull the belt very quickly out of the retractor.
CAUTION:
You can be seriously hurt if your shoulder belt is
too loose. In a crash, you would move forward too
much, which could increase injury. The shoulder
belt should fit against your body.
To unlatch the belt, just push the button on the buckle.

Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear shoulder belt comfort guides will provide added
safety belt comfort for older children who have outgrown
booster seats and for small adults. When installed on a
shoulder belt, the comfort guide better positions the belt
away from the neck and head.
There is one guide for each outside passenger position
in the rear seat. To provide added safety belt comfort
for children who have outgrown child restraints and for
smaller adults, the comfort guides may be installed on
the shoulder belts. Here's how to install a comfort guide
and use the safety belt:
1. Pull the elastic cord out from the edge of the seatback
and the interior body to remove the guide from its
storage clip.

1-35
2. Slide the guide under and past the belt. The elastic
cord must be under the belt. Then, place the guide
over the belt, and insert the two edges of the belt
into the slots of the guide.3. Be sure that the belt is not twisted and it lies flat.
The elastic cord must be under the belt and the guide
on top.
