If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp
six times. 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 front turn signal lamps will flash 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 . See OnStar
for additional information. You should also remember
that you can start your vehicle with the correct ignition
key if the alarm has been set off.

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.

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.

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

If the alarm does not sound when it should but the
lights flash, check to see if the horn works. The horn

If the alarm does not sound or the headlamps do not
flash, see your dealer for service.
