Your vehicle has a feature that may automatically
unlock the doors (if your vehicle has power door
locks), turn the interior lamps on, ash the hazard
warning ashers, and turn off the radio when the
airbag inates. You can lock the doors again by
using the door lock. The interior lamps and hazard
warning ashers will deactivate after approximately
15 minutes. You can use the radio controls to
adjust the radio.
In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur
from the right front passenger airbag.
Airbags are designed to inate only once.
After an airbag inates, you will need some new
parts for the airbag system. If you do not get
them, the airbag system will not be there to help
protect you in another crash. A new system will
include airbag modules and possibly other
parts. The service manual for your vehicle
covers the need to replace other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Recording
and Privacy on page 478andEvent Data
Recorders on page 479.
Let only qualied technicians work on your
airbag system. Improper service can mean
that your airbag system will not work properly.
See your dealer/retailer for service.

{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something
may be wrong with the airbag system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front passenger’s
seat may not have the protection of the
airbag(s). SeeAirbag Readiness Light
on page 185for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can
affect how well the passenger sensing system
operates. You may want to consider not using seat
covers or other aftermarket equipment if your
vehicle has the passenger sensing system.SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 95for more information about
modications that can affect how the system
operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat
cushion and seatback may interfere with
the proper operation of the passenger
sensing system.
93

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be
serviced. There are parts of the airbag system
in several places around your vehicle. You do
not want the system to inate while someone is
working on your vehicle. Your dealer/retailer
and the service manual have information about
servicing your vehicle and the airbag system.
To purchase a service manual, seeService
Publications Ordering Information on page 476.
{CAUTION:
For up to 10 seconds, after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are
close to an airbag when it inates. Avoid
yellow connectors. They are probably
part of the airbag system. Be sure to
follow proper service procedures, and
make sure the person performing work
for you is qualied to do so.
The airbag system does not need regular
maintenance.

Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in range. This
is normal for any RKE system. If the transmitter
does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
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 “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 103.
If you are still having trouble, see your
dealer/retailer or a qualied technician
for service.
Remote Keyless Entry (RKE)
System Operation
If your vehicle has this feature you can lock
and unlock your doors and disarm or arm your
theft-deterrent system from about 3 feet (1 m) up to
30 feet (9 m) away using the Remote Keyless Entry
(RKE) transmitter. SeeContent Theft-Deterrent
on page 115for additional information.

button to unlock the
driver’s door and turn
on the interior lamps.
The parking lamps may
also ash, and the
horn may chirp, when
this button is pressed.
Press the unlock button again within three
seconds and all of the doors will unlock.
LOCK:Press this button to lock all the doors.
The parking lamps may also ash and the

If a locked door is not opened using the RKE
transmitter, or by OnStar®, the pre-alarm will
go off. If the engine is not started or unlock not
pressed within 10 seconds, the front turn
signal lamps will ash for two minutes, and the
horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system will not
activate if you lock the doors with a key, the
manual door lock, or power door lock switch.
The system can only be activated using the
RKE transmitter, or by OnStar
®. SeeOnStar®
System on page 149for additional information.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm
has been set off.
Here is how to avoid setting off the alarm by
accident:
If you do not want to activate the
theft-deterrent system, the vehicle should be
locked with the door key after the doors
are closed.
Always unlock a door with the RKE transmitter.
Unlocking a door any other way will set off
the alarm.If you set off the alarm by accident, you can turn
off the alarm by pressing unlock on the RKE
transmitter. The alarm will not stop if you try to
unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system
by locking the doors with the RKE transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button
on the RKE transmitter or start the engine.
If the alarm does not sound when it should but
the lights ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 433.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer/retailer for
service.

Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder
is turned with a valid key. If an incorrect key is
used or the ignition lock cylinder is tampered with,
the fuel system is disabled and the vehicle will
not start.
During normal operation, the security light will turn
off approximately ve seconds after the engine
is started. SeeSecurity Light on page 196.
If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.If the engine does not start after three tries,
the vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your Passlock
®
system is not working properly and must be
serviced by your dealer/retailer. Your vehicle is
not protected by Passlock
®at this time. See your
dealer/retailer for service.
In an emergency, call the Roadside Assistance
Center. SeeRoadside Assistance Program
on page 466.
Do not leave the key or device that disarms
or deactivates the theft deterrent system in
the vehicle.

Ignition Positions
With the key in
the ignition switch,
you can turn to
four different
positions.
LOCK (A):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. It will locks the steering wheel on manual
transmission vehicles when the key is removed.
It is a theft-deterrent feature. You will only be
able to remove your key when the ignition is
turned to LOCK.If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the
shift lever is in PARK (P).
Notice:Using a tool to force the key from
the ignition switch could cause damage
or break the key. Use the correct key and turn
the key only with your hand. Make sure the
key is all the way in. If it is, turn the steering
wheel left and right while you turn the key
hard. If none of this works, then your vehicle
needs service.
ACC (ACCESSORY) (B):This is the position in
which you can operate your electrical accessories
or items plugged into the accessory power
outlets. On automatic transmission vehicles,
this position unlocks the ignition. On manual
transmission vehicles, it unlocks the ignition and
steering wheel. Use this position if your vehicle
must be pushed or towed.
