Cadillac 2007 STS, Owner'S Manual

Page: 109 / 560

If a door, hood, or the trunk is opened without
the keyless access transmitter, the horn will
sound for 30 seconds and the lamps will flash
for two minutes. The vehicle cannot be started
without a keyless access transmitter.
The Theft-Deterrent system will not arm if:
•
The key is used to turn the key cylinder to
the lock position.
•
The driver’s door is locked using the power
door lock switch after the doors are closed.
If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door
is open or not closed completely, the security
light will flash for 60 seconds and then turn off.
At this time, the theft-deterrent system is armed
but the alarm will not sound if the trunk lid, hood or
door that was not closed completely is tampered
with or opened. The alarm will sound for the
trunk lid, hood or a door that was completely
closed at the time the vehicle was locked using
the keyless access transmitter.
The vehicle can be programmed to automatically
unlock the doors and disarm the theft-deterrent
system when you approach the vehicle and
the keyless access transmitter is with you. See
Vehicle Personalization on page 148 .
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the
driver’s door disarms the theft-deterrent system.
Unlocking a door any other way while the
system is armed will activate the alarm.
Testing the Alarm
1. From inside the vehicle, 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 keyless access transmitter
and close the door. Wait about 30 seconds
until the security light goes off.
3. Reach in and open the door using the inside
door handle. The horn will sound and the
exterior lamps will flash.
You can turn off the alarm by pressing the unlock
button on the keyless access transmitter or by
starting the car.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
