Content Theft-Deterrent - GMC 2009 Yukon XL Owner's Manual

Content Theft-Deterrent

Your vehicle may have a content theft-deterrent alarm
system.
To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE)
transmitter or the power door lock switch. The
security light will come on to inform the driver the
system is arming. If a door is open when the doors
are locked, the security light will flash.
If the delayed locking feature is turned on, the
theft-deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. See Delayed Locking on
page 2-10.
3. Close all doors. The security light should go off after
about 30 seconds. The alarm is not armed until the
security light goes off.
This is the security light.
If a locked door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will flash. If the key is not
placed in the ignition and turned to START or the door
is not unlocked by pressing the unlock button on the
RKE transmitter during the ten second pre-alarm,
the alarm will go off. Your vehicle's headlamps will flash
and the horn will sound for about 30 seconds, then
will turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle's key or the manual door lock.
It activates only if you use the power door lock switch with
the door open or the RKE transmitter. You should also
remember that you can start your vehicle with the correct
ignition key if the alarm has been set off.
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 the doors with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if it is armed.
If you set off the alarm by accident, press unlock on the
RKE transmitter or place the key in the ignition and
turn it to START to turn off the alarm. The alarm will not
stop if you try to unlock a door any other way.
