High Beam Control System (HBC)

The HBC determines the conditions in
front of the vehicle using the Forward
Sensing Camera (FSC) while driving in
darkness to automatically switch the
headlights between high and low
beams.
Refer to Forward Sensing Camera
(FSC) on page 4-198.
While driving the vehicle at a speed of
about 30 km/h (19 mph) or more, the
headlights are switched to high beams
when there are no vehicles ahead or
approaching in the opposite direction.
The system switches the headlights to
low beams when one of the following
occurs:



The system detects a vehicle or the
headlights/lights of a vehicle
approaching in the opposite
direction.



The vehicle is driven on roads lined
with streetlamps or on roads in
well-lit cities and towns.



The vehicle is driven at less than
about 20 km/h (12 mph).



The headlight high-beam indicator
light turns on while the high beams
are on.

The recognition distance of the Forward
Sensing Camera (FSC) varies according to
the surrounding conditions.

The warning light turns on when the
system has a malfunction.
Refer to High Beam Control System
(HBC) Warning Indication/Warning
Light (Amber) on page 7-29.

CAUTION



Do not adjust the vehicle height,
modify the headlight units, or
remove the camera, otherwise the
system will not operate normally.



Do not rely excessively on the HBC
and drive the vehicle while paying
sufficient attention to safety. Switch
the headlights between the high
beams and low beams manually if
necessary.

NOTE

The timing in which the system
switches the headlights changes under
the following conditions. If the system
does not switch the headlights
appropriately, manually switch
between high and low beams
according to the visibility as well as
road and traffic conditions.



When there are sources of light in
the area such as street lamps,
illuminated signboards, and traffic
signals.



When there are reflective objects in
the surrounding area such as
reflective plates and signs.



When visibility is reduced under rain,
snow and foggy conditions.



When driving on roads with sharp
turn or hilly terrain.



When the headlights/rear lamps of
vehicles in front of you or in the
opposite lane are dim or not
illuminated.
