ately 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 judg‐
ment 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.◀
