System Description

NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.

The anti-theft alarm system:
- Protects the vehicle from unauthorized entry into the passenger compartment, engine compartment and liftgate.
- Monitors the status of the ignition key lock cylinder.
- Is controlled by an anti-theft alarm control.
- When armed, detects unauthorized entry into the passenger compartment by using an input from the GEM module regarding the state of the door (open or closed).
- Protects the engine compartment by a hood switch which is located on the LH cowl vent panel and part of windshield wiper motor wiring.
- Triggers an alarm if the ignition lock cylinder is forcibly removed from the steering column.

Once triggered, the system responds by:
- Flashing the low beam headlamps, the parklamps, rear lamps and the alarm indicator warning lamp all of which are located in the instrument panel indicator lamp module.
- Sounding the horn.
- Disabling the starter circuit until the system is disarmed.
