Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. This vehicle has theft-deterrent features, however, they do not make it impossible to steal. To arm the theft-deterrent system: 1. Open the door. 2. Lock the door with the Remote Keyless Entry (RKE) transmitter or the power door lock switch. The security light will come on to inform the driver the system is arming. If a door is open when the doors are locked, the security light will flash. If the delayed locking feature is turned on, the theft‐deterrent system will not start the arming process until the last door is closed and the delay timer has expired. See Delayed Locking on page 3‑11. 3. Close all doors. The security light should go off after about 30 seconds. The alarm is not armed until the security light goes off. The content theft deterrent system does not sense if the midgate or tailgate are open or ajar, therefore, vehicle contents may not be protected if the midgate is left open or ajar. Content Theft-Deterrent Your vehicle has a content theft-deterrent alarm system. This is the security light. 3-27
