Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Content Theft-Deterrent
If your vehicle has the
Remote Keyless Entry
(RKE) system, the
vehicle has a content
theft-deterrent alarm
system.
To activate the content theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the RKE transmitter. The
security light, located on the instrument panel
cluster, will ash.
If the lock button on the RKE transmitter is pressed, but
a door is open, the horn will chirp six times. Press
the lock button again, within three seconds, and the
doors will lock. Close the open door and the system will
be activated.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 2-43for 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.

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 5-110.

lamps do not ash, see your dealer/retailer for service.
Passlock®(U. S. Only)
Passlock®is a passive theft-deterrent system that
enables fuel if the vehicle is started with a valid key.

tampered with, the fuel system is disabled and the
vehicle does not start.
The security light turns off approximately ve seconds
after the engine is started. SeeSecurity Light on
page 3-34.
