running lights turn on automatically whenever the engine is started and the parking
brake is released with the head light switch is in the “AUTO” position. (Illuminate brighter

■Light reminder buzzer
A buzzer sounds when the engine switch is turned off or turned to ACCESSORY mode

■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of passen-
gers and the loading condition of the vehicle to ensure that the headlights do not inter-
fere with other road users.
■If the “AFS OFF” indicator flashes
It may indicate a malfunction in the system. Contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.
■Customization
Settings (e.g. light sensor se nsitivity) can be changed.
(Customizable features: P. 634)
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.

AHS (Adaptive High-beam System)
●
Adjusts the brightness and illuminated area of the high beams according to
the vehicle speed.
● Adjusts the intensity of the high beams, while driving on a curve, so t hat the
area in the direction that the vehicle is turning will be illuminated more brightly
than other areas.
● Operates the variable high beams
so that the area around vehicles
ahead is partially not illuminated
while all other areas continue to be
illuminated with the high beams.
The variable high beams help optimize
forward visibility while reducing the daz-
zling effect on the drivers of vehicles
ahead.
● Adjusts the distance that the low beams are projected according to the dis-
tance to a preceding vehicle.
: If equipped
The Adaptive High-beam System uses a camera sensor located behind the
upper portion of the windshield to assess the brightness of the lights of vehi-
cles ahead, streetlights, etc., and au tomatically controls the headlight light
distribution as necessary.
WARNING
■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 turning the high beam on or off manually if necessary.
■To prevent incorrect operation of the Adaptive High-beam system
Do not overload the vehicle.

■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If AUTO mode is selected while the engine switch is in IGNITION ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -30°C
(-22°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers in any mode other than AUTO mode.
■When the windshield wipers are in temporary operation
AUTO mode cannot be activated even if is pressed.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of raindrops.
An optical sensor is adopted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield 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.
