■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.

●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)

CAUTION
■Limitations of the Adaptive High-beam System
Do not rely on the Adaptive High-beam System. Always drive safely, taking care to
observe your surroundings and turn the high beam on or off manually if necessary.
NOTICE
■Notes when using the Adaptive High-beam System
●Do not touch the camera sensor.
●Do not subject the inside rear view mirror or the camera sensor to a strong
impact.
●Do not disassemble the camera sensor.
●Do not spill liquid onto the inside rear view mirror or the camera sensor.
●Do not apply window tinting or stickers to the camera sensor or the area of wind-
shield near the camera sensor.
●Do not place items on the dashboard. There is a possibility that the camera sensor
will mistake items reflected in the windshield for streetlights, the headlights of
other vehicles, etc.
●Do not install a parking tag or any other accessories near or around the inside
rear view mirror and the camera sensor.
●Do not overload the vehicle.
●Do not modify the vehicle.
●If the windshield needs to be replaced, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Observe the following to ensure that the
Adaptive High-beam System functions cor-
rectly.

3304-5. Using the driving support systems
LS600h/LS600hL_EE(OM50G20E)
■After the vehicle has been parked in the sun
The LKA system functions may not be available and a warning message ( P. 563)
will be displayed for a while after driving has started. In such cases, turn the LKA sys-
tem off and turn it on again after normal temperature returns. When the temperature
in the cabin decreases and the temperature around the camera sensor ( P. 324)
becomes suitable for its operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Raised pavement marker” or stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the li ght level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging

Driving
LS600h/LS600hL_EE(OM50G20E)
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving with a strong crosswind
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, such as snow tires, etc., sufficient performance may not
be maintainable.
■Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the driver
of the need for caution while driving. ( P. 563)
CAUTION
■Before using the LKA system
Do not rely solely on the LKA system. The LKA system does not drive the vehicle
automatically, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsibility for understanding his/her
surroundings, for operating the steering wheel to correct the driving line, and for
driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LKA by mistake
Switch the LKA off using the LKA switch when not in use.
