Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
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 an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also 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 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.

The right front passenger's frontal and side impact air
bags will be turned on anytime the AOS system senses
that a person of adult size is sitting in the right front
passenger seat. When the air bags are turned on,
the ON light in the rearview mirror will stay on to
remind you that the air bags are on.

CAUTION:
If the air bag readiness light on the instrument
panel ever comes on, it means that something
may be wrong with the air bag system. If this
ever happens, have the vehicle serviced promptly,
because an adult
-size person sitting there may
not have the protection of the air bags. See ªAir
Bag Readiness Lightº in the Index for more on
this, including important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the AOS system operates. You may not want
to use seat covers or other aftermarket equipment if your
vehicle has the AOS system.

1-33 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.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners. You'll find
them on the buckle end of the safety belts for the
driver and right front passenger. They help the safety
belts reduce a person's forward movement in a
moderate to severe crash in which the front of the
vehicle hits something.
Pretensioners work only once. If they activate in a crash,
you'll need to get new ones, and probably other new
parts for your safety belt system. See ªReplacing
Restraint System Parts After a Crashº in the Index.

6. To tighten the belt, feed the lap belt back into the
retractor while you push down on the child restraint.
You may find it helpful to use your knee to push
down on the child restraint as you tighten the belt.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If your vehicle has the Automatic Occupant Sensor
(AOS) system, before you begin to drive, check to
be sure the right front passenger's frontal and side
impact air bags are off if you're using a rear
-facing
infant restraint. If the air bags are off, the word OFF
will appear in the rearview mirror.
If the word ON appears in the rearview mirror, the
frontal and side impact air bags have not been turned
off. If this ever happens, unbuckle the safety belt and
perform the steps to install the rear
-facing restraint
again. If the air bags still don't turn off, install the
infant restraint in a rear seat position and have your
vehicle serviced as soon as possible.
