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.

Remember, the theft-deterrent system won't activate if
you lock the doors with a key or use the manual door
lock. It activates only if you use a power door lock
button or the remote keyless entry transmitter.
To avoid activating the alarm by accident,
do the following:

Always unlock a door with a known key or use the
remote keyless entry transmitter. (Using a known
key or pressing the unlock button on the remote
keyless entry transmitter disables the theft
-deterrent
system.) Unlocking a door any other way, such
as using an unknown key, will activate the
alarm system.

The vehicle should be locked with the door key after
the doors are closed if you don't want to activate the
theft
-deterrent system.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the remote keyless entry
transmitter or by starting the vehicle with a known key.
The alarm won't stop if you try to unlock a door any
other way.
Testing the Alarm
1. From inside the vehicle, roll down the window, then
get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock
the vehicle using the power door lock or the remote
keyless entry transmitter and close the door. Wait
30 seconds until the SECURITY light goes off.
3. Reach in and unlock the door using the manual lock
lever and open the door. The horn will sound and the
headlamps will flash.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see ªFuses and Circuit Breakersº
in the Index. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always activate the
theft
-deterrent system when leaving your vehicle.
