Camera sensor detection information ●
The high beam may not be automatically turned off in the following situations:
• When oncoming vehicles 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 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 vehicle 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 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 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, cu rve, 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 cause the low beams to remain on or the high
beams to cause problems for pedestrians, ve hicles ahead or other parties. In these
cases, manually switch betw een the high and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to th ose of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are changing color,
or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeated ly driving ascendin g/descending roads, or roads with
rough, bumpy or uneven surfaces (such as stone-paved roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly re flective, 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.
• The high beam and low beam are repeated ly being switched be tween in an abnor-
mal manner.
