Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/4/22
26 Keys, Doors, and Windows
To avoid setting off the alarm
by accident:
.Lock the vehicle after all
occupants have left the
vehicle and all doors are
closed.
.Always unlock a door with
the remote key or use the
Keyless Access system.
Unlatching the driver door
with the mechanical key will
not disarm the system or turn
off the alarm.
How to Detect a Tamper
Condition
IfKis pressed on the remote
key and the horn chirps and
the lights flash three times, a
previous alarm occurred while
the system was armed.
If the alarm has been
activated, a message will
appear on the DIC.
Power Sounder,
Inclination Sensor, and
Intrusion Sensor
In addition to the standard
theft-deterrent system
features, this system may also
have a power sounder,
inclination sensor, and
intrusion sensor.
The power sounder provides
an audible alarm which is
distinct from the vehicle’s
horn. It has its own power
source, and can sound an
alarm if the vehicle’s battery is
compromised.
The inclination sensor can set
off the alarm if it senses
movement of the vehicle, such
as when a tire is removed.
Make sure the vehicle's alarm
is not armed prior to any
jacking. The intrusion sensor monitors
the vehicle interior, and can
activate the alarm if it senses
unauthorized entry into the
vehicle's interior. Do not allow
passengers or pets to remain
in the vehicle when the
intrusion sensor is activated.
Before arming the
theft-deterrent system and
activating the intrusion sensor:
.Make sure all doors and
windows are completely
closed.
.Secure any loose items such
as sun glasses.
.Make sure there are no
obstructions blocking the
sensors in the front
overhead console.
