■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if necessary.
■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 another vehicle cuts across in front of you.
●High beam may be turned off if an oncoming vehicle that is using fog lights with-
out using the headlights is detected.
●Houselights, streetlights, 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 pre-ceding vehicles
• Road conditions (wetness, ice, snow etc.)
• The number of passengers and amount of baggage
●High beam may be turned on or off when unexpected by the driver.

●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should consider turning the high beam 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 inside rear view mirror or camera sensor is deformed or dirty.
• Surrounding brightness levels are equal to those of headlights, tail lights orfog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are chang-
ing color, or are not aimed properly.
• 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 mir- ror.
• 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 Automatic High Beam indicator is flashing.
• The high beam and low beam are repeatedly being switched between in an abnormal manner.
