1Press the Automatic High Beam
switch.
2 Turn the headlight switch to the
or position.
The Automatic High Beam indicator will come on when the system is operating.
■Conditions to turn the high beams on/off
automatically
●When all of the follo
wing conditions are
met, the high beams will be turned on
automatically (after approximately 1 sec-
ond):
• The vehicle speed is approximately 21 mph (34 km/h) or more.
• 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 high beams will turn off automatically:
• 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 dete ction 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 repeated 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-
AHB (Automatic High
Beam)
The Automatic High Beam uses a
camera sensor located behind the
upper portion of the windshield to
assess the brightness of the lights of
vehicles ahead, streetlights, etc.,
and automatically turns the high
beams on or off as necessary.
WARNING
■Limitations of the Automatic High
Beam
Do not overly rely on the Automatic High
Beam. Always drive sa fely, taking care to
observe your surroundings and turning
the high beams on or off manually if nec-
essary.
■To prevent incorrect operation of the
Automatic High Beam system
Do not overload the vehicle.

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.
• 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 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 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,
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• 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
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.

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 un til drip prevention
wiper sweep occurs)
With low speed wind shield wiper opera-
tion selected, wiper operation will be
switched from low sp eed to intermittent
wiper operation only when the vehicle is
stationary.
■Raindrop sensor (vehicles with
rain-sensing wind shield 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.
