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

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

• 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.

tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the Intermittent wiper
interval.
■Raindrop sensor (vehicles with rain-
sensing windshield wipers)
●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc. are
present on the windshield.
●If the wiper switch is turned to the
