CAUTION
■Head restraint precautions
Observe the following precautions regarding the head restraints. Failure to do so
may result in death or serious injury.
●Use the head restraints designed for each respective seat.
●Adjust the head restraints to the correct position at all times.
●Manual type: After adjusting the head restraints, push down on them and make
sure they are locked in position.
●Do not drive with the head restraints removed.
■The active head restraint on the front passenger seat (if equipped)
Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which may prevents the sensor from
detecting the passenger’s weight properly. As a result, the active head restraint
may not activate in the event of an accident.
■Active head restraint precautions (if equipped)
●Do not put head restraint covers.
●For removal, installation, modification, disassembly or disposal of the active head
restraints, contact at any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Inappropriate handling of the active head restraints may prevent them from oper-
ating properly during an accident.

LS600h/LS600hL_EE(OM50G20E)
■To prevent sensor error
To ensure that the sensors operate properly,
do not touch or cover them.
CAUTION
Do not adjust the position of the mirror while driving.
Doing so may lead to mishandling of the vehicle and cause an accident, resulting in
death or serious injury.

AFS (Adaptive Front-lighting System) secures excellent visibility at inter-
sections 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 10 km/h (6 mph) or higher.
■Daytime running light system
To make your vehicle more visible to othe r drivers during daytime driving, the day-
time running lights turn on automatically whenever the hybrid system is started and
the parking brake is released with the headlight switch off or in the position. (Illu-
minate brighter than the front position lights.)
Daytime running lights are not designed for use at night.
■Headlight control sensor
■Automatic light off system
●When the light switch is in or : The headlights turn off automatically if the
power switch is turned to ACCESSORY mode or turned off.
●When the light switch is in : The headlights and all lights turn off automatically if
the power switch is turned to ACCESSORY mode or turned off.
To turn the lights on again, turn the po wer 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.
AFS (Adaptive Front-lighting System)
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

2724-3. Operating the lights and wipers
LS600h/LS600hL_EE(OM50G20E)
■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.
■Battery-saving function
In the following conditions, the remaining lights will go off automatically after 20
minutes in order to prevent the vehicle battery from being discharged:
●The headlights and/or tail lights are on.
●The power switch is turned to ACCESSORY mode or turned off.
●The light switch is in or .
This function will be canceled in any of the following situations:
●When the power switch is turned to ON mode.
●When the light switch is operated.
●When the door or trunk is opened or closed.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 634)
NOTICE
■To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the hybrid system is off.

Driving
LS600h/LS600hL_EE(OM50G20E)
When variable shade beam is on,
the illumination of the area sur-
rounding oncoming vehicles and
preceding vehicles is partially
shielded while all other areas con-
tinue to be illuminated in high beam.
This enables forward lighting to be
optimized without blinding sur-
rounding traffic.
If oncoming or preceding vehicles
change position, the shielded area
changes and adapts to the vehicle’s
position.
AHS (Adaptive High-beam System)
The Adaptive High-beam System uses an in-vehicle camera sensor to
assess the brightness of streetlights , the lights of oncoming and preced-
ing vehicles, etc., and automatically turns high beam and variable shade
beam on or off as necessary.

■The Adaptive High-beam System can be operated when
The power switch is in ON mode.
■Camera sensor detection information
●High beam may not be automatically turned off or changed to variable shade beam
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 or variable shade beam may be changed to if an
oncoming vehicle that is using fog lights without using the headlights is detected.
●House lights, street lights, red traffic signals, and illuminated billboards or signs may
cause the high beam to turn off or variable shade beam to be changed to and may
change the area that is shielded.
●The following factors may affect the amount of time taken to turn high beam on or
off, or the speed by which the shielded areas change:
• The brightness of headlights, fog lights, and tail lights of oncoming and preced-
ing vehicles
• The movement and direction of oncoming 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 the road surface etc.)
• The number of passengers and amount of luggage
●High beam and variable shade beam may be turned on or off when unexpected by
the driver.
●Small vehicles, such as bicycles, may not be detected.

2784-3. Operating the lights and wipers
LS600h/LS600hL_EE(OM50G20E)
●In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose oncoming or preceding vehi-
cles to the high beam or may continue using the low beam. Therefore, in these
situations you should consider turning the high beams on or off manually rather
than relying on the Adaptive High-beam System.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The inside rear view mirror or 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 that are either switched off, dirty, are changing
color, or have are not aimed properly.
• When driving through an area of intermittently 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 reflective 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.
■Turning the high beam on during Adaptive High-beam System operation (vehicles
without near-infrared ray transmitters)
When the vehicle is traveling at a high speed, the system will turn on the inner high
beam together with the outer high beam.
■Customization
The variable shade beam can be turned off. (Customizable features P. 634)
