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. To arm the system, do the following: 1. Lock the door using the Remote Keyless Entry (RKE) transmitter or the power door lock switch. 2. Close all the doors. The security light will come on. It should go off within approximately 30 seconds. Your security system is now armed. If a door or a trunk is opened without a key or a RKE transmitter, the horn will sound and the lamps will flash for up to 30 seconds. The theft-deterrent system will not arm if you lock the doors with a key or use the manual door lock. It activates only if you use the RKE transmitter or the power lock on the door. Theft-Deterrent System If your vehicle has this feature, the security light is located on the instrument panel cluster. If the ignition is off and a door is open, the security light will flash, reminding you to arm the theft-deterrent system. 107
