AVALON_U_(L/O_0802)
■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and the
parking brake is released. Daytime r unning 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 START STOP” switch or the engine switch has been
switched to ACC or turned OFF while the headlights are turned on. (The
lights turn off immediately if the button on the key is pressed after all
doors are locked.)
To turn the lights on again, switch to ON mode, or turn the light switch OFF
once and then back to the
or position.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. light sensor sensitivity) can be changed. 
(Customizable features P. 429)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary if the engine is not running.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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 con-
trol system to malfunction.

AVALON_U_(L/O_0802)
■
The windshield wiper and washer can be operated when
The “ENGINE START STOP” switch or the engine switch is in ON mode.
■ Dripping prevention wiper sweep
After washing and wiping operation 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 106
mph (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 preven-
tion wiper sweep occurs)
With “LO” selected, wiper operation will be switched from low speed to inter-
mittent wiper operation only when the vehicle is stationary.
■ Rain drop sensor (vehicles equipped with the raindrop detection wind-
shield wipers)
■ 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 sensor judges the amount of rain-
drops.
