Camera sensor detection information
■
● The high beams may not be automatically
changed to the shaded high beams in the
following situations:
• When vehicles ahead suddenly appear
from a curve
• When the vehicle is cut in front of by
another vehicle
• When vehicles ahead are hidden from
sight due to repeated curves, road divid-
ers or roadside trees
• When vehicles ahead appear from the
faraway lane on wide road
• When vehicles ahead have no lights
The high beams may be changed to the
●
shaded high beams if a vehicle ahead that
*
is using fog lights without its headlights
turned on is detected.
House lights, street lights, traffic signals,
●
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the shaded high
beams, cause the high beams not to
change to the shaded high beams, or
change the area that is not illuminated.
● The following factors may affect the
amount of time taken to turn the high
beam on or off, or the speed by which the
areas not illuminated change:
• The brightness of headlights, fog lights,
and tail lights of vehicles ahead
• The movement and direction of vehicles
ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled
vehicle
• The condition of the road (gradient,
curve, condition of the road surface etc.)
