Anti-Theft - Perimeter

Arming The Perimeter Alarm

The perimeter alarm is ready to arm any time the ignition is off. The perimeter alarm pre-arms when:

- pressing the lock button on a programmed RKE (Remote Keyless Entry) transmitter.

- pressing the door lock control switch to the LOCK position with the door open, then closing the door.

- locking the vehicle with the IA (Intelligent Access) feature.

Once the system is pre-armed, there is an 11-second countdown before the perimeter alarm is armed. Each entry point to the vehicle (hood, doors, or liftgate/luggage compartment lid) is armed separately and must be closed before that entry point begins the 11-second countdown to become armed. If all entry points are closed, the turn signals flash indicating that all entry points are entering the 11-second countdown.

Perimeter Alarm Activation

The perimeter alarm has a 12-second delay when the driver door is unlocked and opened using a key in the door lock cylinder. During the delay, a chime sounds. If the perimeter alarm is not disarmed within the 12-second delay, the alarm is activated.

The perimeter alarm is activated when:

- any passenger door, liftgate/luggage compartment lid, or the hood is opened without first receiving an electronic unlock command from a RKE (Remote Keyless Entry) transmitter.

- the driver door is opened without first receiving an unlock command from a RKE (Remote Keyless Entry) transmitter or IA (Intelligent Access) command and the 12-second delay has expired.

- the passenger door or liftgate/luggage compartment lid is opened without first receiving an IA (Intelligent Access) command.

The perimeter alarm only activates 10 times per arming cycle. After that the alarm does not activate. To enable the perimeter alarm again, disarm the perimeter alarm and then arm it again.

Disarming The Perimeter Alarm

The perimeter alarm can be disarmed by:

- pressing the unlock button on a programmed RKE (Remote Keyless Entry) transmitter.

- pressing the liftgate/luggage compartment lid release button on a programmed RKE (Remote Keyless Entry) transmitter.

- unlock any door with the IA (Intelligent Access) feature.

- open the liftgate/luggage compartment lid with the IA (Intelligent Access) feature.

- a programmed IA (Intelligent Access) key is inside the vehicle and the start/stop switch is pressed.

Intelligent Access (IA) Key Disable

For security reasons, when the perimeter alarm enters an armed state, the RFA (Remote Function Actuator) module searches the interior of the vehicle for any programmed IA (Intelligent Access) keys. If the RFA (Remote Function Actuator) module detects any programmed IA (Intelligent Access) keys inside the vehicle when the perimeter alarm is armed, it disables the IA (Intelligent Access) key. The RKE (Remote Keyless Entry) and the IA (Intelligent Access) functions of that key still operate, but the RFA (Remote Function Actuator) module ignores any start command associated with that key. The disabled IA (Intelligent Access) key is enabled when the perimeter alarm is disarmed.
