using the Forward Sensing Camera (FSC) while driving in darkness to automatically switch 
the headlights between high and low beams.
  Refer to Warning/Indicator Lights on page  4-20 .
  While driving the vehicle at a speed of about 30 km/h (18 mph), the headlights are switched 
to high beams when there are no vehicles ahead or approaching in the opposite direction.
