it is programmed from the factory to lock all doors
automatically when the shift lever is moved out
of PARK (P). All the doors will unlock when

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
If your vehicle has the
remote keyless entry
system, the vehicle has
a content theft-deterrent
alarm system.
112
Page 113 of 492

To activate the content theft-deterrent system,
do the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
If the lock button on the remote keyless entry
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 remote
keyless entry 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 remote keyless
entry transmitter, or by OnStar
®. SeeOnStar®
System on page 146for 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 remote keyless
entry 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 remote
keyless entry transmitter. The alarm will not stop if
you try to unlock a door any other way.
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. 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 remote keyless entry transmitter or
start the engine.
