Position of switch : the low beams are activated and off automatically, e.g., in tunnels, in twilight or if there is precipitation. The indicator lamp in the instrument cluster lights up.
When emerging from a tunnel during the day, the low beams are not switched off immediately but instead only after approx. 2 minutes.
A blue sky with the sun low on the horizon can cause the lights to be switched on.
The low beams always stay on when the fog lights are activated.
Personal responsibility
The automatic headlight control cannot serve as a substitute for your personal judgment in determining when to turn the lights on in response to ambient lighting conditions.
E. g. the sensors are unable to detect fog or hazy weather. To avoid safety risks under these conditions, you should always switch on the lights manually.
