• When the vehicle is cut in front of by
another vehicle
• When vehicles ahead cannot be
detected due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear in a far-
away lane on a wide road
• When the lights of vehicles ahead are
not on
●
The high beams may be turned off if a
vehicle ahead that is using fog lights
without its headlights turned on is
detected.
●
House lights, street lights, traffic sig-
nals, and illuminated billboards or
signs and other reflective objects may
cause the high beams to change to
the low beams, or the low beams to
remain on.
●
The following factors may affect the
amount of time taken for the high
beams to turn on or off:
• The brightness of the 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.)
• The number of passengers and
amount of luggage in the vehicle
●
The high beams may turn on or off
unexpectedly.
●
Bicycles or similar vehicles may not
be detected.
●
In the following situations the system
may not be able to correctly detect the
surrounding brightness level. This
may cause the low beams to remain
on or the high beams to flash or daz-
zle pedestrians or vehicles ahead. In
such a case, it is necessary to manu-
ally switch between the high and low
beams.

(heavy rain, snow, fog, sandstorms,

• When the vehicle's headlights are
damaged or dirty, or are not aimed
properly
• When the vehicle is listing or titling
due to a flat tire, a trailer being towed,
