160 2-3. Operating the lights and wipers
■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 running lights are not designed for use at
night.
■ Headlight control sensor
■ Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30
seconds after all doors are closed with the engine switch turned to the
ACC or LOCK position. (The lights turn off immediately if the LOCK but-
ton on the wireless remote control is pressed twice after all doors are
locked.)
● When only the tail lights come on: The tail lights turn off automatically
with the engine switch turned to the ACC or LOCK position and the
driver’s door is opened.
If the driver’s door is kept open, the lights automatically turn off after 30 min-
utes.
To turn the lights on again, turn the engine switch to the ON position, or turn
the headlight 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. 495)
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 sys-
tem to malfunction.
