• The area ahead of the vehicle is dark.
• There are no vehicles ahead with head- lights or tail lights turned on.
• There are few streetlights on the road ahead.
●If any of the following conditions is met,

• The vehicle speed is below approxi-
mately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■Camera sensor detection information
●The high beams may not be automatically
turned off in the following situations:
• 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 repe ated curves, road
dividers or roadside trees
• When vehicles ahead appear in a far- away 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 using fog lights with- out its headlights turn
ed on is detected.
●House lights, street lig hts, 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

●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 corre ctly 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 swit ch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fo g, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or dam- aged
• 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 headl ights, tail lights or
fog lights

windshield wipers, which operate
regardless of vehicle speed or amount
of raindrops. The intermittent wind-
shield wiper operation can be switched

once. After this, the headlight cleaners will
operate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The engine switch is in IGNITION ON
mode.
■Dripping prevention wiper sweep
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 wiper opera-
tion (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the following even
when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is
being used (delay until drip prevention
wiper sweep occurs)
With low speed windshield wiper opera-
tion selected, wiper operation will be
switched from low speed to intermittent
wiper operation only when the vehicle is
stationary.
■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 is turned to AUTO mode
while the engine switch is in IGNITION ON mode, the wipers will operate once
to show that AUTO mode is activated.
●If the temperature of
the raindrop sensor
is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation
may not occur. In this case, operate the
wipers in any mode other than AUTO
mode.
■When the windshield wipers are in tem-
porary operation (vehicles with
rain-sensing wind shield wipers)
AUTO mode cannot be activated even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not
blocked if there is wash er fluid in the wind-
shield washer fluid reservoir.
WARNING
■Caution regarding the use of wind-
shield wipers in AUTO mode
The windshield wipers may operate
unexpectedly if the se nsor is touched or
the windshield is subj ect to vibration in
AUTO mode. Take care that your fingers
or anything else do not become caught
in the windshield wipers.
■Caution regarding the use of washer
fluid
When it is cold, do not use the washer
fluid until the windshield becomes warm.
The fluid may freeze on the windshield
and cause low visibility. This may lead to
an accident, resulting in death or serious
injury.
NOTICE
■When there is no washer fluid spray
from the nozzle
Damage to the washer fluid pump may
be caused if the lever is pulled toward
you and held continually.
