4-3. Operating the lights and wipers
shaded high beams, or change the
area that is not illuminated.
The following factors may affect the
amount of time taken to turn the high
beam on or off, or the speed by which
the areas not illuminated change:
• The brightness of headlights, fog
lights, and tail lights of vehicles ahead
• The movement and direction of vehi-
cles ahead
• When a vehicle ahead only has oper-
ational 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 light distribution control of the
headlights may change unexpectedly.
Bicycles or similar objects may not be
detected.
In the following situations the system
may not be able to correctly detect the
surrounding brightness level. This
may cause the low beams to remain
on or the high beams to flash or daz-
zle pedestrians or vehicles ahead. In
such a case, it is necessary to manu-
ally switch between the high and low
beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms,
etc.)
• When the windshield is obscured by
fog, mist, ice, dirt, etc.
• When the windshield is cracked or
damaged
• When the front camera is deformed or
dirty
• When the temperature of the front
camera is extremely high
• When the surrounding brightness
level is equal to that of headlights, tail
lights or fog lights
• When headlights or tail lights of vehi-
cles ahead are turned off, dirty,
changing color, or not aimed properly
• When the vehicle is hit by water,
snow, dust, etc. from a preceding
vehicle
• When driving through an area of inter-
mittently changing brightness and
darkness
• When frequently and repeatedly driv-
ing on ascending/descending roads,
or roads with rough, bumpy or uneven
surfaces (such as stone-paved roads,
gravel roads, etc.)
• When frequently and repeatedly tak-
ing curves or driving on a winding
road
• When there is a highly reflective
object ahead of the vehicle, such as a
sign or mirror
• When the back of a preceding vehicle
is highly reflective, such as a con-
tainer on a truck
• When the vehicle's headlights are
damaged or dirty, or are not aimed
properly
• When the vehicle is listing or tilting
due to a flat tire, a trailer being towed,
etc.
• When the headlights are changed
between the high beams and low
beams repeatedly in an abnormal
manner
• When the driver believes that the high
beams may be flashing or dazzling
pedestrians or other drivers
• When the vehicle is used in an area in
which vehicles travel on the opposite
side of the road of the country for
which the vehicle was designed, for
example using a vehicle designed for
right-hand traffic in a left-hand traffic
area, or vice versa
