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 a locked door is not opened using the remote keyless entry transmitter, or by OnStar®, the alarm will go off. First, a pre-alarm will sound the horn at reduced intensity for 10 seconds. Then, the front turn signal lamps will flash for two minutes, and the horn will sound for two minutes. The alarm will then turn off to save battery power. Starting the engine with the correct key will shut off the pre-alarm or alarm at any time. Remember, the theft-deterrent system will not activate if you lock the doors with the key, the manual door lock, or power door lock switch. The system can only be activated using the remote keyless entry transmitter, or by OnStar®. See OnStar® System on page 2-48 for additional information. You should also remember that you can start your vehicle with the correct key if the alarm has been set off. Here is how to avoid setting off the alarm by accident: Content Theft-Deterrent Your vehicle has a content theft-deterrent alarm system. To activate the content theft-deterrent system: 1. Close all the doors. 2. Lock the doors with the remote keyless entry transmitter. The security light, located on the instrument panel cluster, will flash. If the lock button on the remote keyless entry transmitter is pressed, but a door is open, the doors will lock, the lights may flash and the horn may sound. Close the open door and the alarm system will arm. • If you do not want to arm the theft-deterrent system, the vehicle should be locked with the manual door lock lever, the power door lock switch, or the key, after the doors are closed. • If the content theft-deterrent system is armed, unlock the doors by pressing the unlock button on the remote keyless entry transmitter or by OnStar®. Unlocking a door any other way will activate the alarm. 2-14
