1 With the headlights on, push the
lever away from you to turn on the
high beams.Pull the lever toward you to the center
position to turn the high beams off.
2 Pull the lever toward you and
release it to flash the high beams
once.You can flash the high beams with the
headlights on or off. When the following conditions are met,
while the headlights (low beam) are on,
the cornering lights will additionally
turn on and light up the direction of
movement for the vehicle. This is to
ensure excellent visibility when either
driving at intersections or parking at
night.
 The steering wheel is operated
 The turn signal lever is operated
 The shift lever is in R
However, when vehicle speed is 25
mph (40 km/h) or above, the corner-
ing lights do not turn on.
When the cornering lights are on for
more than 30 minutes, they will auto-
matically turn off.
AFS (Adaptive Front-lighting System)
secures excellent visibility at intersec-
tions and on curves by automatically
adjusting the direction of the light axis
of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input. AFS operates at speeds of 6 mph (10 km/
h) or higher.NOTICE■
To prevent 12-volt battery discharge
Do not leave the lights on longer than
necessary when the hy brid system is off.

When all of the following conditions are ful-
filled, high beam will be automatically
turned on: ●
Vehicle speed is above approximately 21
mph (34 km/h). ●
The area ahead of the vehicle is dark. ●
There are no oncoming or preceding
vehicles with headlights or tail lights
turned on. ●
There are few streetlights on the road
ahead.
If any of the following conditions are ful-

mately 17 mph (27 km/h). ●
The area ahead of the vehicle is not dark. ●
Oncoming or preceding vehicles have

Camera sensor dete ction information●
High beam may not be automatically
turned off in the following situations:
• When oncoming vehicles suddenly
appear from a curve
• When the vehicle is cut in front of by
another
• When oncoming or preceding vehicles
are hidden from sight due to repeated
curves, road dividers or roadside trees
●
High beam may be turned off if an
oncoming vehicle that is using fog lights
without using the headlights 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
amount of time taken to turn high beam
on or off:
• The brightness of headlights, fog lights, Automatic High Beam The Automatic High Beam uses an
in-vehicle camera sensor to assess
the brightness of streetlights, the
lights of oncoming and preceding
vehicles, etc., and automatically
turns high beam on or off as neces-
sary.

Driving 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
• When a oncoming or preceding vehicle
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●
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.
• In bad weather (rain, snow, fog, sand-
storms, etc.)
• The windshield is obscured by fog, mist,
ice, dirt, etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is
extremely high.
• Surrounding brightness levels are equal
to those of headlights, tail lights or fog
lights.
• Vehicles ahead have headlights or tail
lights that are either switched off, dirty,
are changing color, or are not aimed
properly.
• 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
tracks, etc.).
• When frequently and repeatedly taking
curves or driving on a winding road.
• There is a highly re flective object ahead
of the vehicle, such as a sign or a mirror.
• The back of a vehicle ahead is highly
reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or
dirty. • The vehicle is listing or titling, due to a flat
tire, a trailer being towed, etc.
• The driver believes that the high beam
may be causing problems or distress to
other drivers or pedestrians nearby.
WARNING■
Limitations of the Automatic High
Beam

Beam. Always drive safely, taking care to
observe your surroundings and turning
high beam on or off manually if neces-
sary.

• Accelerator status
•Brake status
• Vehicle speed
• Operation status of the pre-collision

• Information (such as the distance
and relative speed between your
vehicle and the vehicle ahead or
other objects)
• Images from the camera sensor
(available only when the pre-colli-
