Keys, Doors and Windows 2-17 Vehicle Security This vehicle has theft-deterrent features; however, they do not make it impossible to steal. Anti-Theft Alarm System Your vehicle has a content theft-deterrent alarm system. 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 2‑8. 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. If a locked driver door is opened without using the RKE transmitter, a ten second pre-alarm will occur. The horn will chirp and the lights will flash. If the key is not placed in the ignition and turned to START or the door is not unlocked by pressing the unlock button on the RKE transmitter during the ten second pre-alarm, the alarm will go off. Your vehicle's headlamps will flash and the horn will sound for about 30 seconds, then will turn off to save the battery power. The theft-deterrent system will not activate if the doors are locked with the vehicle's key or the manual door lock. It activates only if you use the power door lock switch with the door open or the RKE transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. To avoid setting off the alarm by accident: . This is the security light. 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 you do not want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. Always unlock the doors with the RKE transmitter. Unlocking a door any other way will set off the alarm if it is armed. .
