cally turned off in the following situa-
tions:
• When oncoming vehicles suddenly
appear from a curve

another vehicle
• When vehicles ahead are hidden from
sight due to repeated curves, road
dividers or roadside trees

• When vehicles ahead have no lights
● The high beam may be turned off if a
vehicle ahead that is using fog lights
without using the headlights is
detected.
● House lights, street lights, traffic sig-
nals, and illuminated billboards or
signs may cause the high beam to
switch to the low beams, or the low
beams to remain on.
● The following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehi-
cles ahead
• When a vehicle ahead only has oper-
ational 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.)

amount of luggage
● The high beam may be turned on or
off when the driver does not expect it.
● Bicycles or similar objects may not be
detected.
● In the situations shown below, the
system may not be able to accurately
detect surrounding brightness levels.
This may cause the low beams to
remain on or the high beams to cause
problems for pedestrians, vehicles
