1524-3. Operating the lights and wipers
1With 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.
2Pull 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.
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 speed s of approximately
6 mph (10 km/h) or higher.
When any of the following conditions is
met, while the headlights (low beam)
are on, the cornering lights will addi- tionally turn on and light up the direc-
tion of movement for the vehicle. This is
to ensure excellent visibility when
either driving at intersections or park-
ing at night.

The steering wheel is operated
 The turn signal lever is operated
 The shift position is in R (both left
and right side cornering lights)
■Cornering light control
●The lights illuminate when the vehicle
speed is approximately 19 mph (30
km/h) or less. However, the lights turn off
when the vehicle speed increases to
approximately 22 mph (35 km/h) or
more.
●After the lights remain illuminated for 30
minutes, they automatically turn off.

■High beam automatic turning on or off
conditions
●When all of the follo
wing conditions are
met, the high beam will be automatically
turned on (after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).
• 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 are met,
the high beam will be automatically

• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail
lights turned on.
• There are many streetlights on the road
ahead.
■Camera sensor dete ction information
●The 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 vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road divid-
ers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead have no lights
●The high beam may be turned off if a
vehicle ahead that is using fog lights with-
Automatic High Beam
The Automatic High Beam uses an
in-vehicle camera sensor to assess
the brightness of streetlights, the
lights of vehicle ahead, etc., and
automatically turn s the high beam
on or off as necessary.
WARNING
■Limitations of the Automatic High
Beam
Do not rely on the Automatic High
Beam. Always drive sa fely, taking care to

Activating the Automatic High
Beam system

1544-3. Operating the lights and wipers
out using the headlights is detected.
●House lights, street lights, traffic signals,
and illuminated billboards or signs may
cause the high beam to switch to the low
beams, or the low beams to remain on.
●The following factors may affect the
amount of time taken to turn the high
beam on or off:
• The brightness of 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 the road surface etc.)
• The number of passengers and amount of
luggage
●The high beam may be turned on or off
when the driver does not expect it.
●Bicycles or similar objects may not be
detected.
●In the situations show n below, the system
may not be able to accurately detect sur-
rounding brightness levels. This may
cause the low beams to remain on or the
high beams to cause problems for pedes-
trians, vehicles ahead or other parties. In
these cases, manually switch between the
high and low beams.
• 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.
• When the temperature of the camera sensor is extremely high
• Surrounding brightness levels are equal to those of headlights, 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 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 tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeat-
edly being switched between in an
abnormal manner.
• The driver believes that the high beam
may be causing problems or distress to
other drivers or pedestrians nearby.
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.

●Replace the compact spare tire with a
standard tire as soon as possible.
●Avoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
■When the compact spare tire is
attached
The vehicle speed may not be correctly
detected, and the following systems may
not operate correctly:
• ABS & Brake assist
•VSC
•TRAC
• Dynamic radar cruise control with full- speed range
