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.

Automatic High Beam

: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to assess the
brightness of streetlights, the lights of vehicles ahead, etc., and automatically
turns the high beam on or off as necessary.
WARNING
■Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Al ways 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 Automatic High Beam system
Do not overload the vehicle.

GS350_200t_GS F_OM_OM30F83E_(EE)
■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.
