1884-3. Operating the lights and wipers
LS500h_OM_(U)_1809The 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 turn off 30 seconds
after the driver’s door is opened and
closed if the power switch is turned to
ACCESSORY mode or turned off. (The
lights turn off immediately if on the
key is pressed after all the doors are
closed.)
●When only the tail lights are on: The tail
lights turn off automatically if the power
switch is turned to ACCESSORY mode
or turned off and the driver’s door is
opened.
To turn the lights on again, turn the power
switch to ON mode, or turn the light switch
off once and then back to or .
■Light reminder buzzer
A buzzer sounds when the power switch is
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.
■12-volt battery-saving function
In order to prevent the 12-volt battery of the
vehicle from discharging, if the headlights
and/or tail lights are on when the power switch is turned off the 12-volt battery sav-
ing function will operate and automatically
turn off all the lights
after approximately 20
minutes. When the power switch is turned
to ON mode, the 12-volt battery-saving
function will be disabled.
When any of the following are performed,
the 12-volt battery-saving function is can-
celed once and then reactivated. All the
lights will turn off automatically 20 minutes
after the 12-volt battery-saving function has
been reactivated:
●When the headlight switch is operated
●When a door is opened or closed
■Welcome light illumination control
The parking lights and tail lights automati-
cally turn on at night when the doors are
unlocked using the entr y function or wire-
less remote control if the light switch is in
the position.
■Customization
Some functions can be customized.

■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.

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

Driving
vehicle ahead that is using fog lights with-
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.
1 Turn the power switch on while the fol-
lowing conditions are met.
●The headlight switch is in or .

Washer/wiper dual opera-
tion
Pulling the lever operates the wipers and
washer.
(After operating several times, the wipers
operate once more time after a short delay
to prevent dripping. However, the dripping
prevention does not operate while the
vehicle is moving.)
Vehicles with headlight cleaners:
When the power switch is in ON mode
and the headlights are on, if the lever is
pulled, the headlight cleaners will operate
once. After this, the he adlight cleaners will
operate every 5th time the lever is pulled.
■The windshield wiper and washer can be
operated when
The power switch is in ON mode.
■Effects of vehicle speed on wiper opera-
tion
Even when the wipers are not in AUTO
mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.
With low speed windsh ield wiper operation
selected, wiper operation will be switched
from low speed to intermittent wiper opera-
tion only when the vehicle is stationary.
(However, when the sensor sensitivity is
adjusted to the highes t level, the mode can-
not be switched.)
■Raindrop sensor
●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.
