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.
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
or in a near
-deployment crash. 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, right front passenger's
or rear 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 side impact air bag. Do not
open or break the air bag coverings.
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.

Leaving Your Vehicle
If you are leaving the vehicle, open the door, set the
locks from the inside, get out and close the door.
Remote Keyless Entry System
With this feature, you can lock and unlock your doors or
unlock your trunk from about 3 feet (1 m) up to 30 feet
(9 m) away using the remote keyless entry transmitter
supplied with your vehicle.
Your remote keyless entry transmitter operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.

Check the distance. You may be too far from your
vehicle. You may need to stand closer during rainy
or snowy weather.

Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.

Check to determine if battery replacement is
necessary. See the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.

2-11
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
Since all vehicles come with only two transmitters, you
must check with your dealer for information on how to
obtain additional transmitters.
All transmitters must be present when replacement or
additional transmitters are being programmed.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.

1. Use a coin to pry open the transmitter.
2. Once the transmitter is separated, use a pencil
(or similar object) to remove the old battery.
Do not use a metal object.3. Replace the battery. Insert the new battery as the
instructions under the cover indicate.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Check the operation of the transmitter.
