Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal.
Content Theft-Deterrent
Your vehicle may be equipped with a content
theft-deterrent alarm system.
The security light
is located on the
instrument panel
cluster. SeeSecurity
Light on page 3-49for
additional information.
To activate the theft-deterrent system, do the following:
1. Close all the doors.
2. Lock the door with the remote keyless entry
transmitter. The security light should come
on and ash.If the lock button on the remote keyless entry
transmitter is pressed, but a door is open, you may
hear three chimes indicating delayed locking is
enabled. SeeDelayed Locking on page 2-10for
additional information. Close the door and the
content theft-deterrent system will be activated.
If a locked door is opened without using the remote
keyless entry transmitter or OnStar, if equipped with
an active subscription, the alarm will go off. Your
vehicle’s lamps will ash and the horn will sound for
about two minutes, then will turn off to save the battery
power. If this occurs, you can turn off the alarm by
pressing unlock on the remote keyless entry transmitter
or by placing the key in the ignition and turning it
to START.
If your vehicle has a Driver Information Center (DIC),
you can customize your alarm warning. SeeDIC Vehicle
Customization on page 3-67for additional information.
The horn may chirp for 10 seconds before the alarm
goes off if the theft-deterrent system is activated using
the remote keyless entry transmitter and the driver’s
door is opened. If this occurs, you can turn off the
alarm by pressing unlock on the remote keyless entry
transmitter or by placing the key in the ignition and
turning it to START.
2-17

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 remote keyless
entry transmitter.
If you set off the alarm by accident, turn off the alarm
by pressing unlock on the remote keyless entry
transmitter or by placing the key in the ignition and
turning it to START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Wait for the security light to go out.
3. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
4. Turn off the alarm by pressing unlock on the remote
keyless entry transmitter or by placing the key in
the ignition and turning it to START.
If the alarm does not sound when it should,
but the vehicle’s headlamps ash, check to see
if the horn works. The horn fuse may be blown.To replace the fuse, seeInstrument Panel Fuse
Block on page 5-107andUnderhood Fuse Block
on page 5-109.
If the alarm does not sound or the vehicle’s headlamps
do not ash, see your dealer for service.
Passlock®
Your vehicle is equipped with 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 a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light ashes, wait
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 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. Your
vehicle is not protected by Passlock
®at this time. You
may also want to check the fuse. SeeFuses and Circuit
Breakers on page 5-106. See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
