■Headlight control sensor
■Automatic light off system
●When the light switch is in : The headlig hts 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.

■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.
■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. 568)
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 detectingthe level of ambient light and may cause the
automatic headlight system to malfunction.

■Conditions in which the light distribution control of the headlights changes automati-
cally
●When all of the following conditions are met, the high beams will be turned on automat- ically and the system will operate:
• The vehicle speed is approximately 60 km/h (37 mph) or more.*
*: The area in the direction that the vehicl e is turning will be illuminated more brightly
than other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will turn on and the distance that the low be ams are projected will be adjusted automatically, depending
on the location of vehicles ahead:
• The vehicle speed is approximately 60 km/h (37 mph) or more. • The area ahead of the vehicle is dark.
• There are vehicles ahead with headlights or tail lights turned on.
●If any of the following conditions is met, the high beams or variable high beams will be
changed to the low beams automatically:

roadside trees • When vehicles ahead appear from the faraway lane on wide road• When vehicles ahead have no lights
●The high beams may be changed to the variable high beams if a vehicle ahead that isusing fog lights without its headlights turned on is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs may cause the high beams to change to the variable high beams, cause the high beams not tochange to the variable high beams, or change the area that is not illuminated.
●The following factors may affect the amount of time taken to turn the high beam on or off, or the speed by which the areas not illuminated change:
• The brightness of headlights, fog light s, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead • When a vehicle ahead only has operational lights on one side
