2-3. Operating the lights and windshield wipers
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
■Automatic light off system
The headlights and tail lights turn off 30 seconds after a door is opened or closed if
the engine switch is turned to the “ACC” or “LOCK” position while the headlights
are turned on. (The lights turn off immediately if the “LOCK” button on the key is
pressed after all doors are locked.)
To turn the lights on again, turn the engine switch to the “ON” position, or turn the
light switch “OFF” once and then back to the or position.
■Customization that can be configured at Lexus dealer
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features →P. 4 3 6 )
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

When driving
■The windshield wiper and washer can be operated when

■Dripping prevention wiper sweep
After washing and wiping operation several times, the wipers operate one more
time after a short delay to prevent dripping.

(170 km/h).
■Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not in “AUTO” mode.
●Intermittent wiper interval (“INT” mode)
●Wiper operation when the washer is being used (delay until drip prevention
wiper sweep occurs)
With “LO” selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary.
■Rain drop sensor (vehicles equipped with the rain-sensing windshield wipers)
■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.
■In extremely hot or cold weather
The system will turn off if the windshield gets extremely hot (more than 194 °F
[90 °C]) or cold (less than 14 °F [-10 °C]).The sensor judges the amount of raindrops.
