If no light-dark border with rising asymmetric portion can be
seen in the left headlight (right-hand drive) or in the right head‐
light (left-hand drive), the “city light” function must be deactiva‐
ted.
The city light feature is used to ensure that oncoming traffic is
not dazzled up to a speed of 30 km/h in city traffic.
