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 one of the following: • Press the lock button on the keyless access transmitter. If the door is closed when the lock button is pressed, the security light will stay illuminated for 30 seconds. After the security light goes off, the theft-deterrent system is armed. Pressing the lock button twice will arm the system immediately. Theft-Deterrent System Your vehicle has a theft-deterrent alarm system. The security light is located on the instrument panel cluster. • Open the door. Lock the door with the power door lock switch or lock button on the keyless access transmitter. The security light should flash. Close the door. The security light will stop flashing and stay on. After 30 seconds the light should turn off, the theft-deterrent system is armed. • Passive Arming, if activated through the vehicle personalization feature, will arm the system automatically after you close the door and take at least one keyless access transmitter with you. The security light will turn on. After 60 seconds the light should turn off. The theft-deterrent system is armed. See Vehicle Personalization on page 2-47. If a door, hood or the trunk is opened without the keyless access transmitter, the horn will sound for 30 seconds and the lamps will flash for two minutes. The vehicle cannot be started without a keyless access transmitter. If the ignition is off and a door is open, the security light will flash, reminding you to arm the theft-deterrent system. 2-20
