● High beam may be turned off if an
oncoming vehicle that is using fog lights
without using the headlights is detected.
House lights, street lights, red traffic sig-
●
nals, and illuminated billboards or signs
may cause the high beam to turn off.
● The following factors may affect the
amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights,
and tail lights of oncoming and preceding
vehicles
• The movement and direction of oncom-
ing and preceding vehicles
• When a oncoming or preceding vehicle
only has operational lights on one side
• When a oncoming or preceding vehicle
is a two-wheeled vehicle
• The condition of the road (gradient,
curve, condition of the road surface, etc.)
• The number of passengers and amount of
luggage
● High beam may be turned on or off when
unexpected by the driver.
In the situations below, the system may
●
not be able to correctly detect the sur-
rounding brightness levels, and may flash
or expose nearby pedestrians to the high
beam. Therefore, you should consider
turning the high beams on or off manually
rather than relying on the Automatic
High Beam system.
