LS500_OM_OM50F54U_(U) The sensor may not function properly if an
object is placed on th e sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion. ■
Automatic light off system●
When the headlights are on: The head-
lights and tail lights tu rn off 30 seconds
after the driver’s door is opened and

closed.)●
When only the tail lights are on: The tail
lights turn off automatically if the engine
switch is turned to ACCESSORY mode
or turned off and the driver’s door is
opened.
To turn the lights on again, turn the engine
switch to IGNITION ON mode, or turn the
light switch off once and then back to

turned off or turned to ACCESSORY
mode and the driver’s door is opened while
the lights are turned on. ■
Automatic headlight leveling system
The level of the headlights is automatically
adjusted according to the number of pas-
sengers and the loading condition of the
vehicle to ensure that the headlights do not
interfere with other road users.
■
Windshield wiper linked headlight illu-
mination
When driving during daytime with the
headlight switch turned to , if the wind-
shield wipers are used, the headlights will
turn on automatically after several seconds
to help enhance the visibility of your vehicle.
■
Battery-saving function
In order to prevent the battery of the vehicle from discharging, if the headlights and/or
tail lights are on when the engine switch is
turned off the battery saving function will
operate and automatically turn off all the
lights after approximately 20 minutes.
When the engine switch is turned to IGNI-
TION ON mode, the battery-saving func-
tion will be disabled.
When any of the following are performed,
the battery-saving function is canceled
once and then reactivated. All the lights will
turn off automatically 20 minutes after the
Battery- saving function has been reacti-
vated: ●

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.
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 the steering wheel or turn
signal lever is operated while the
headlights are on (low beam), a cor-
nering light will turn on and light up
the direction of movement of the
vehicle. The cornering lights are
designed to ensure excellent visibil-
ity when making a turn at an inter-
section. However, when vehicle speed is approxi-
mately 22 mph (35 km/h) or higher, the
cornering lights will not turn on. When the shift position is in R while
the headlights are on (low beam),
both cornering lights will turn on.
This is designed to enhance visibility
when parking. ■
Cornering lights
When the cornering lights are on for more
than 30 minutes, they will turn off automati-
cally.

■
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 are 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 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.

Driving vehicle ahead that is using fog lights with-
out its headlights turned 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
• 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.
