●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 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.)

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
