■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.
●Compared to turning on th e 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

minutes.
■Light reminder buzzer
A buzzer sounds when the engine 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
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.
