When driving
■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 ignition key has been turned to the “ACC” or “LOCK” 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 ignition key to the “ON” position, or turn the light
switch “OFF” once and then back to the or position.
■Customization
Settings (e.g. light sensor sensitivity) can be changed. ( P. 3 8 9 )
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.
