Anti-Theft - Perimeter

Arming the Perimeter Alarm

The perimeter alarm is ready to arm any time the ignition is off. Any of the following pre-arms the alarm system:

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

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

- touching the 7/8 and 9/0 buttons simultaneously on the keyless entry keypad.

Once the system is pre-armed, there is a 20-second countdown before the perimeter alarm is armed. Each entry point to the vehicle (hood, door, or liftgate) is armed separately and must be closed before that entry point begins the 20-second countdown to become armed. If all entry points are closed, the turn signals flash indicating that all entry points are entering the 20-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 and TO STOP ALARM START VEHICLE is displayed in the message center. 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, or the hood is opened without first receiving an electronic unlock command from a RKE (Remote Keyless Entry) transmitter or keyless entry keypad.

- the driver door is opened without first receiving an unlock command from a RKE (Remote Keyless Entry) transmitter or keyless entry keypad 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 RKE (Remote Keyless Entry) transmitter.

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

- using a programmed key to transition the ignition to the RUN mode.

- entering the correct vehicle unlock code on the keyless entry keypad.

The perimeter alarm can be deactivated by pressing the panic button on a RKE (Remote Keyless Entry) transmitter. All of the lamps stop flashing and the horn stops sounding, but the alarm is still armed.
