nDaytime running light system
lTo make your vehicle more visible to other drivers, the daytime running lights
turn on automatically 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.

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.
