other vehicles or objects, i.e. road sign
or similar to this, for a long time
ț the system is overheated

restart the engine if:
ț the dirt (e.g. slush) loosens while you are driving
ț the system detects that the sensors* are fully available again

systems, etc. ̈ Wait until the message in the multifunction display disappears.
