Camera sensor detection information
●The high beams may not be automatically turned off in the follo wing situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on
● The high beams may be turned off if a vehicle ahead that is usi ng fog lights
without 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 t he 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 operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the r oad surface,
etc.)
• The number of passengers and amount of luggage in the vehicle
● The high beams may turn on or off unexpectedly.
● Bicycles or similar vehicles 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 r emain on
or the high beams to flash or dazzle pedestrians or vehicles ah ead. In such
a case, it is necessary to manually switch between the high and low beams.
• When driving in inclement weather (heavy rain, snow, fog, sand storms,
etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or damaged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of head lights, tail
lights or 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 prec eding vehi-
cle
• When driving through an area of intermittently changing brightness and
darkness
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel roads, etc.)

■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing win dshield
wipers)
After performing a washing and wiping operation several times, the wipers
operate one more time after a short delay to prevent dripping.
However, this final wiper operation will not be performed while driving.
■ Effects of vehicle speed on wip er operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation va ries
depending on vehicle speed when the washer is being used (delay until drip
prevention wiper sweep occurs).
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wiper will operate once to show that “AUTO” mod e is acti-
vated.
● When the sensor sensitivity ring is turned toward high while in “AUTO”
mode, the wipers will operate once to indicate that the sensor sensitivity is
enhanced.
● If the temperature of the raindrop sensor is 194°F (90°C) or hi gher, or 5°F
(-15°C) or lower, automatic operation may not occur. In this ca se, operate
the wipers in any mode other than “AUTO”.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washe r fluid in the
windshield washer fluid reservoir. ● 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.
