4-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the parking lights turn on auto-
matically (at an increased intensity) whenever the engine is started
and the parking brake is released. Daytime running lights are not designed for use
at night.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel econ-
omy.
■Headlight control sensor
■Automatic light off system
When the light switch is in : The headlig hts and tail lights turn off 30 seconds
after the “START STOP ENGINE” <“POWER”> switch is turned to ACCESSORY
mode or turned off and a door is opened and all of the doors and trunk are closed.
(The lights turn off immediately if on th e key is pressed twice after all the doors
are closed.)
To turn the lights on again, turn the “START STOP ENGINE” <“POWER”> switch to
IGNITION ON mode, or turn the li ght switch off once and then back to

If any of the doors or trunk lid is kept op en, the lights automatically turn off after 20
minutes.
■Light reminder buzzer
A buzzer sounds when the “START STOP ENGINE” <“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 (if equipped)
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading conditio n of the vehicle to ensure that the headlights do not
interfere with other road users. The sensor may not func tion 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.
