heavy precipitation or fog

grille (

Distronic* becomes operational again without
the engine being restarted when
ț dirt on the radiator grille has fallen off while
driving (e.g. slush or snow)
ț the system recognizes full sensor
availability due to lessening rain or because
the road is drying, for example
ț the message in the multifunction display
disappears
You can then operate Distronic* as usual again.
