Cadillac 2007 CTS, Owner'S Manual, Page: 108 / 518

To avoid activating the alarm by accident do the
following:
•
Lock the door with the key or the manual door
lock after the doors are closed if you do not
want to arm the theft-deterrent system.
•
Always unlock a door with a key or use the
RKE transmitter. Pressing the unlock button
on the RKE transmitter disables the
theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the
driver’s door with your key. You can also turn
off the alarm by using the unlock button on
the RKE transmitter, or by starting the vehicle with
a valid key.
Testing the Alarm
1. Roll down the window, then get out of the
vehicle, keeping the door open.
2. From outside of the vehicle, with the door
open, lock the vehicle using the power door
lock switch or the RKE transmitter and
close the door. Wait approximately 30 seconds
until the security light goes off.
3. Reach in and unlock the door using the
manual lock and open the door. The horn
will sound and the exterior lamps will flash.
The alarm can be turned off by unlocking the
driver’s door with the key, using the unlock button
on the RKE transmitter or by starting the car
with a valid key.
If the alarm does not sound when it should, check
to see if the horn works. The horn fuse may be
blown. To replace the fuse, see
Fuses and Circuit
Breakers on page 447 . If the fuse does not
need to be replaced, you may need to have your
vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.
