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 IKT (Integrated Keyhead Transmitter) or RKE (Remote Keyless Entry) transmitter.

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

Once the system is pre-armed, there is a 11-second countdown before the perimeter alarm is armed. Each entry point to the vehicle (hood, door, 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 programmed IKT (Integrated Keyhead Transmitter) or RKE (Remote Keyless Entry) transmitter.

- the driver door is opened without first receiving an unlock command from a programmed IKT (Integrated Keyhead Transmitter) or RKE (Remote Keyless Entry) transmitter and the 12-second delay has expired.

- the ignition is transitioned to RUN without a valid PATS (Passive Anti-Theft System) key read received.

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 IKT (Integrated Keyhead Transmitter) or RKE (Remote Keyless Entry) transmitter.

- using a programmed IKT (Integrated Keyhead Transmitter) or PATS (Passive Anti-Theft System) key to transition the ignition to the RUN mode.

- pressing the liftgate/luggage compartment lid release button on a programmed IKT (Integrated Keyhead Transmitter) or RKE (Remote Keyless Entry) transmitter (this only disarms the perimeter alarm for the liftgate/luggage compartment lid).
