Security Alarm

With the security system armed, manually opening the hood, the tailgate, or moving the door lock knob to the unlock position activates the security alarm. Alternatively, the security alarm sounds, the headlights low beam, the front parking lights, the taillights, the license plate light, and the side marker lights blink, repeating this alarm (one cycle is 120 seconds). Even if you remove the 12 volt battery, the alarming state cannot be changed. The alarm starts again when reinstalling the 12 volt battery.
