When the headlights and taillights have been turned on by operating the light control switch, if the ignition switch is turned OFF, the driver’s door is opened and closed, this system will continue to illuminate the headlights and taillights for approximately 30 seconds, and then turn the headlights OFF. If, within the 30 second period, all the doors are locked, and the “LOCK” button on the transmitter is pushed, the headlights and taillights will be turned OFF immediately.
