■The Automatic High Beam can be operated when
The engine switch is in IGNITION ON mode.
■Camera sensor detection information
●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 oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees
●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 signals, 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 oncoming and preceding vehicles
• When an oncoming or preceding vehicle only has operational lights on one side
• When an 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.
●Small vehicles, such as bicycles, may not be detected.
●In the situations below, the system may not be able to correctly detect the surrounding
brightness levels, and may flash or expose nearby pedestrians to the high beam. There-
fore, you should consider turning the high beams on or off manually rather than relying
on the Automatic High Beam system.
• 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.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty, chang-
ing color, or have improperly adjusted aim.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeatedly driving ascending/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 vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or distress to other
drivers or pedestrians nearby.
• The vehicle is used in a territory in which vehicles travel on the opposite side of the
road of the country for which the vehicle is approved, for example using a vehicle
designed for right-hand traffic in a left-hand traffic territory, or vice versa.

sor.
