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. If the lock button on the remote keyless entry transmitter is pressed, but a door is open, you may hear three chimes indicating delayed locking is enabled. See Delayed Locking on page 2-10 for additional information. Close the door and the content theft-deterrent system will be activated. If a locked door is opened without using the remote keyless entry transmitter or OnStar, if equipped with an active subscription, the alarm will go off. Your vehicle's lamps will flash and the horn will sound for about two minutes, then will turn off to save the battery power. If this occurs, you can turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. If your vehicle has a Driver Information Center (DIC), you can customize your alarm warning. See DIC Vehicle Customization on page 3-67 for additional information. The horn may chirp for 10 seconds before the alarm goes off if the theft-deterrent system is activated using the remote keyless entry transmitter and the driver's door is opened. If this occurs, you can turn off the alarm by pressing unlock on the remote keyless entry transmitter or by placing the key in the ignition and turning it to START. Content Theft-Deterrent Your vehicle may be equipped with a content theft-deterrent alarm system. The security light is located on the instrument panel cluster. See Security Light on page 3-49 for additional information. To activate the theft-deterrent system, do the following: 1. Close all the doors. 2. Lock the door with the remote keyless entry transmitter. The security light should come on and flash. 2-17
