curves, road dividers or roadside trees
●High beam may be turned off if an
oncoming vehicle that is using fog lights
without using the head lights is detected.
●House lights, street lights, red traffic sig-
nals, 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 oncom- ing and preceding vehicles
• When a oncoming or preceding vehicle only has operational lights on one side
• When a oncoming or preceding vehicle
is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of th e road surface, etc.)
• The number of passengers and amount of luggage
●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 beams on or off manually
rather than relying on the Automatic
High Beam system.
• In bad weather (rain, snow, fog, sand-
storms, 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 those of headlights, tail lights or fog
lights.
• Vehicles ahead have headlights or tail lights that are either switched off, dirty,
are changing color, or are not aimed
properly.
• When driving through an area of inter-
mittently changing brightness and dark-
ness.
• 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 re flective object ahead
of the vehicle, such as a sign or a mirror.
• 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 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.
NOTICE

strikes the windshield, or if bugs, etc. are
present on the windshield.
●If the wiper switch is turned to the
position while the power switch is in ON
mode, the wipers will operate once to
