Camera sensor dete ction information●
The high beam may not be automatically turned off in the following situations:
• When oncoming vehicles sudd enly 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 dividers or
roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights ●
The high beam may be turned off if a vehicl e ahead that is using fog lights without using
the headlights is detected. ●
House lights, street lights, traffic signals, and illuminated billboards or signs may cause
the high beam to switch to the low be ams, 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 headlig hts, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational 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 ●
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 sur-
rounding brightness levels. This may caus e the low beams to remain on or the high
beams to cause problems for pedestrians, vehicles ahead or other parties. In these
cases, manually switch between the high and low beams.

• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
