WARNINGThe automatic driving lamp control (position ) only operates as a sup-
port and does not release the driver from his responsibility to check the
lights and, if necessary, to switch on the light depending on the prevailing
light conditions.
CAUTION
Poorer visibility is detected by a sensor mounted below the windscreen in the
holder of the inside mirror or in the control panel. Do not cover the sensor -
the system can be affected.
Note
The setting (activate/deactivate) of the automatic driving light control during
rain is stored (depending on the Infotainment type) in the active user account

If there is a fault, the error message will appear in the instrument cluster dis-
play. Seek help from a specialist garage.WARNINGThe system is used only for support, thus the driver is not released from his
obligation to manually adjust the main or low beam according to the given
ambient conditions (e.g. in unfavourable lighting and weather conditions, as when passing poorly lit road users, if necessary, when the area in front of
the sensor is covered by an obstacle).
CAUTION
Do not cover the sensor and keep the front screen clean - system functionality
can be impaired.
Note
The setting for the high-beam assistant in Infotainment is stored (depending
on the Infotainment type) in the active user account for personalisation
