4-3. Operating the lights and wipers
■Daytime running light system

time running lights turn on automatically whenever the hybrid system is started and

tion. (Illuminate brighter than the parking lights.) 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.

greater durability and consumes less electricity, so it can help improve fuel econ-
omy.

■Automatic headlight leveling system
The level of the headlights is automatically adjusted according to the number of pas-
sengers and the loading condition of the vehi cle to ensure that the headlights do not
interfere with other road users. 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.
