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. 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. If a door is opened without the key or remote keyless entry transmitter, the alarm will go off. Your vehicle's lamps will flash and the horn will sound for 30 seconds. The lamps and horn will then turn off to save battery power. Remember, the content theft-deterrent system will not activate if you lock the doors with a key or use the manual door lock. It activates only if you use a power door lock switch with a door open, or with the remote keyless entry transmitter. You should also remember that you can start your vehicle with the correct ignition key if the alarm has been set off. Here is how to avoid setting off the alarm by accident: Content Theft-Deterrent Your vehicle may have a content theft-deterrent alarm system. With this system, the SECURITY light, located on the instrument panel cluster, will flash as you open the door if your ignition is off. This light reminds you to activate the content theft-deterrent system when leaving your vehicle. To activate the system, do the following: 1. Open the door. 2. Lock the door with the power door lock switch or with the remote keyless entry transmitter. The SECURITY light should come on and stay on. • 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 a door with a key, or use the remote keyless entry transmitter. Unlocking a door any other way will set off the alarm. If you set off the alarm by accident, unlock the driver's door with your key. You can also turn off the alarm by pressing the unlock button on the remote keyless entry transmitter. The alarm will not stop if you try to unlock a door any other way. 2-18
