There are two lights for lighting up the ground ("puddle lights") in the front front doors.The driver''s front door control unit detects the door status, notifies the Body Computer and controls the switching on of the light in the two doors.The opening of one of the front doors causes the two lights to come on for a maximum of 3 minutes; when this time has expired the light can only be switched back on again after the door has been reopened.The closing of the driver''s door causes the two lights to go out immediately.
