Driving
out 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 opera-
tional 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
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• 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.
• 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,
changing color, or have improperly
adjusted aim.
• 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 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.
