2-14 Keys, Doors, and Windows To avoid setting off the alarm by accident: . . Immobilizer Operation This vehicle has a passive theft-deterrent system. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the key is removed from the ignition. The system is automatically disarmed when the vehicle is started with the correct key. The key uses a transponder that matches an immobilizer control unit in the vehicle and automatically disarms the system. Only an authorized key starts the vehicle. The vehicle may not start if the key is damaged. Press K on the RKE transmitter. The security light in the instrument cluster comes on if there is a problem with arming or disarming the theft-deterrent system. When trying to start the vehicle, the security light comes on briefly when the ignition is turned on. 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 engine still does not start, and the key appears to be undamaged or the light continues to stay on, try another ignition key. If the engine does not start with the other key, the vehicle needs service. If the vehicle does start, the first key may be damaged. See your dealer who can service the theft-deterrent system and have a new key made. Do not leave the key or device that disarms or deactivates the theft-deterrent system in the vehicle. 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 RKE transmitter. . Unlocking the driver door with the key will not disarm the system or turn off the alarm. How to Detect a Tamper Condition If K is pressed on the transmitter and the horn chirps three times, an alarm occurred previously while the alarm system was armed.
