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)

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.

2824-3. Operating the lights and wipers
LS600h/LS600hL_EE(OM50G20E)
■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■Dripping prevention wiper sweep
After washing and the wiper has operated several times, the wipers operate one
more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 170 km/h
(106 mph).
■Effects of vehicle speed on wiper operation
Even when the wipers are not in “AUTO” mode, vehicle speed affects the time until
the drip prevention wiper sweep occurs.
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle is sta-
tionary.
(However, when the sensor sensitivity is adjusted to the highest level, the mode can-
not be switched.)
■Raindrop sensor
●If the wiper is turned to “AUTO” mode wh ile the power switch is in ON mode, the
wipers will operate once to show that “AUTO” mode is activated.
●If the temperature of the raindrop sensor is 90°C (194°F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers in any mode other than “AUTO” mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
■Outside rear view mirror defogger activation linked to windshield wiper operation
The outside rear view mirror defoggers automatically turn on when you operate the
windshield wipers.
The outside rear view mirror defoggers automatically turn off approximately 15 min-
utes after the wipers stop.
For details about the outside rear view mirror defoggers: P. 425
●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.

CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers or
anything else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm.
The fluid may freeze on the windshield and cause low visibility. This may lead to an
accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward you
and held continually.
■When a nozzle becomes blocked
In this case, contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Range 4 or higher has been selected by using the paddle shift.
(vehicles with paddle shift switch)
●Vehicle speed is above approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle -to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following
situations:
●Actual vehicle speed falls below approximately 40 km/h (25 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off by pressing the VSC OFF switch.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed (when the wiper switch is set to
the “AUTO” mode or the high speed wiper operation position).
●When snow mode is set.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
