Buick Enclave: Anti-theft Alarm System
On vehicles with an anti-theft alarm system, to activate the system:
► Press
on the Remote Keyless Entry
(RKE) transmitter or the power door lock switch when any door is open.
The security light flashes.
When the door is closed, the security light stops flashing and stays on solid for approximately 30 seconds.
The content theft-deterrent alarm is not armed until the security light goes off.
If the delayed locking feature is active, the alarm is not activated until all doors are closed and the security light goes off.
► Press when the driver door is closed.
The security light comes on solid for approximately 30 seconds and then goes off.
The content theft-deterrent alarm is not armed until the security light goes off.
The theft-deterrent system will not activate if the doors are locked with the vehicle's key or the manual door lock.
If a locked door is opened without using the RKE transmitter, a 10-second pre-alarm occurs.
The horn chirps and the lights flash.
If the key is not placed in the ignition and turned to START or the door is not
unlocked by pressing during the 10-second
pre-alarm, the alarm goes off.
The headlamps flash and the horn sounds for about 30 seconds, then turns off to save the battery power.
The vehicle can be started with the correct ignition key if the alarm has been set off.
To avoid setting off the alarm by accident:
► Lock the vehicle with the door key after the doors are closed. ► Unlock the door with the RKE transmitter. Unlocking a door any other way sets off the alarm if the system has been armed.Press 
or place the key in the ignition
and turn it to START to turn off the alarm.
