Activating the Automatic High
Beam

1844-3. Operating the lights and wipers
●The high beams may be turned off if a
vehicle ahead that is using fog lights with-
out its headlights turned on is detected.
●House lights, street lights, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the 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 th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle
●The high beams may turn on or off unex-
pectedly.
●Bicycles or similar vehicles may not be
detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually 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.

fog lights
• When headlights or tail lights of vehicles 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 dark-
ness
• When frequently and repeatedly driving ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,

• 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 container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling 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
