Vehicle Security
Vehicle theft is big business,
especially in some cities. This
vehicle has theft-deterrent features,
however, they do not make it
impossible to steal.
Anti-Theft Alarm System
This vehicle has a content
theft-deterrent alarm system.
The security light is located on the
instrument panel cluster.
To arm the system:
1. Close all the doors.
2. Lock the doors with the RemoteKeyless Entry (RKE) transmitter.
The security light flashes. If the lock button on the RKE
transmitter is pressed, but a door is
open, the doors lock, the lights may
flash and the horn may sound.
Close the open door to arm the
system.
The alarm goes off if a locked door
is not opened using the RKE
transmitter, or by OnStar
®.
A pre-alarm sounds the horn at
reduced intensity for 10 seconds.
Then, the front turn signal lamps
flash for two minutes, and the horn
sounds for two minutes. The alarm
then turns off to save battery power.
Start the engine to turn off the
alarm.
The theft-deterrent system does
not activate if the doors are locked
with the key, the manual door lock,
or power door lock switch. The
system can only be activated using
the RKE transmitter, or by OnStar.
See the OnStar Owner's Guide for
additional information. The vehicle
can be started with the correct key if
the alarm has been set off.
