Theft-Deterrent Systems Vehicle theft is big business, especially in some cities. Although your vehicle has a number of theft-deterrent features, we know that nothing we put on it can make it impossible to steal. However, there are ways you can help. If the vehicle is equipped with OnStar®, and OnStar® locks the doors, with all the doors closed, it will activate the system. If the lock button on the remote keyless entry transmitter is pressed, but a door is open, the horn will chirp six times. Close the open door and the system will be activated. If a locked door is not opened with the remote keyless entry transmitter, or OnStar®, the alarm will go off. The front turn signal lamps will flash for two minutes, and the horn will sound for two minutes, then will turn off to save the battery power. Remember, the theft-deterrent system won't activate if you lock the doors with a key, the manual door lock, or power door lock switch. The system can only be activated with the remote keyless entry transmitter, or OnStar®. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here's how to avoid setting off the alarm by accident: Content Theft-Deterrent If your vehicle has the remote keyless entry system, the vehicle has a content theft-deterrent alarm system. To activate the content theft-deterrent system, do the following: 1. Close all the doors. 2. Lock the door with the remote keyless entry transmitter. The security light flashes. • If you don't want to activate the theft-deterrent system, the vehicle should be locked with the door key after the doors are closed. • Always unlock a door with a the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm. 2-16
