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.
NOTE
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.
The low beams may not switch to
high beams when cornering.
Operation of the High Beam Control
System (HBC) function can be
disabled. Refer to Personalisation
Features on page 9-10 .
