Vehicle Security

This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm system.
The indicator light, on the instrument panel near the windshield, indicates the status of the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured during
the delay to arm the system.
KEYS, DOORS, AND WINDOWS 23
Fast Flash : Vehicle is unsecured. A door, the hood, or the trunk is open.
Slow Flash : Alarm system is armed.
Arming the Alarm System
1. Turn off the vehicle.
2. Lock the vehicle in one of three ways:
.
Use the remote key.
.
Use the Keyless Access system.
.
With a door open, press Q on the interior of the door.
3. After 30 seconds the alarm system will arm, and the indicator light will begin to slowly f lash indicating the alarm system is operating.
Pressing second time will bypass the 30-second delay and immediately arm the alarm system.
The vehicle alarm system will not arm if the doors are locked with the mechanical key.
If the driver door is opened without first unlocking with the remote key, the horn will chirp and the lights will flash to indicate pre-alarm. If the
Q on the remote key a

vehicle is not started, or the door is not unlocked by pressing
K on the
remote key during the 10-second pre-alarm, the alarm will be activated.
The alarm will also be activated if a passenger door, the trunk, or the hood is opened without first disarming the system. When the alarm is activated, the turn signals f lash and the horn sounds for about 30 seconds. The alarm system will then re-arm to monitor the next unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn off the alarm if it has been activated:
.
Press K on the remote key.
.
Unlock the vehicle using the Keyless Access system.
.
Start the vehicle.
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
If K is 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.
.
Close DVD screens before leaving the vehicle.
Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-14584312) - 2021 - crc - 7/7/20
Inclination and Intrusion Sensor Disable Switch
It is recommended that the intrusion and inclination sensor be deactivated if pets are left in the vehicle or the vehicle is being transported. With the
vehicle turned off, press front overhead console. The indicator light will come on momentarily, indicating that these sensors have been disabled for the next alarm system arming cycle.

Steering Column Lock
If equipped, the steering column lock is a theft-deterrent device. This feature locks the steering column when the vehicle is turned off and the driver door is opened, or when the driver door is opened and then the vehicle is turned off. The steering column unlocks when the vehicle is turned on.
The Driver Information Center (DIC) may display one of these messages:
.
A message to service the steering column lock indicates that an issue has been detected with the column lock feature and the vehicle should be serviced.
.
A message that the steering column is locked indicates that the engine is running, but the steering column is still locked. It is normal for the column to be locked during a remote start, but the column should unlock after the brake pedal is pressed and the vehicle is started. No message will display during a remote start.
KEYS, DOORS, AND WINDOWS 25
.
A message that the steering wheel must be turned and the vehicle must be started again indicates that the column lock mechanism is bound, the column locking device was unable to unlock the steering column, and the vehicle did not start. If this happens, immediately turn the steering wheel from side to side to unbind the column lock. If this does not unlock the steering column, turn the vehicle off and open the driver door to reset the system. Then turn the vehicle on and immediately turn the steering wheel side to side for about 15 seconds. In some cases, it may take significant force to unbind the column.
To keep the steering column from binding, straighten the front wheels before turning off the vehicle.
Immobilizer
See Radio Frequency Statement 0 409.
Immobilizer Operation
This vehicle has a passive theft-deterrent system.
Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-14584312) - 2021 - crc - 7/7/20
26 KEYS, DOORS, AND WINDOWS
The system does not have to be manually armed or disarmed.
The vehicle is automatically immobilized when the vehicle is turned off.
The immobilization system is disarmed when the ignition is turned on or to ACC/ACCESSORY and a valid remote key is present in the vehicle.
The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system.
The system has one or more remote keys matched to an immobilizer control unit in the vehicle. Only a correctly matched remote key will start the vehicle. If the remote key is ever damaged, you may not be able to start your vehicle.
When trying to start the vehicle, the security light may come on briefly.
If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again.
If the vehicle will not change ignition modes (ACC/ACCESSORY, on, off), and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the backup location. See
Remote Keyless Entry (RKE) System Operation 0 7.
If the ignition modes will not change with the other remote key or in the backup location, the vehicle needs service. If the ignition does change modes, the first remote key may be faulty. See your dealer.
It is possible for the immobilizer system to learn new or replacement remote keys. Up to eight remote keys can be programmed for the vehicle. To program additional remote keys, see “Programming Remote Keys to the Vehicle” under Remote Keyless Entry (RKE) System Operation 0 7.
Do not leave the remote key or device that disarms or deactivates the theft-deterrent system in the vehicle.
