         To Operate the System
            The  High  Beam  Control  System  (HBC) 
operates to switch the headlights 
automatically between high and low 
beams after the ignition is switched ON 
and the headlight switch is in the AUTO 
and high beam position.
  The High Beam Control System (HBC) 
determines that it is dark based on the 
brightness of the surrounding area. At the 
same time, the High Beam Control System 
(HBC) indicator light (green) in the 
instrument cluster illuminates.
  
 
 
   N O T E
   y   When the vehicle speed is about 30 
km/h (19 mph) or more, the headlights 
automatically switch to high beams 
when there are no vehicles ahead or 
approaching in the opposite direction.    
 
   When the vehicle speed is less than 
about 20 km/h (12 mph), the High Beam 
Control System (HBC) switches the 
headlights to low beams.
   
 
 
 y    The low beams may not switch to high 
beams when cornering.
   
 
 
 y    Operation of the High Beam Control 
System (HBC) function can be disabled.
