An operational disruption in the car may have different causes and is not necessarily due to a direct fault.
Some functions have limitations in special situations and circumstances, or require that certain conditions are fulfilled in order to work. The driver display and centre display may show messages in order to inform about such events.

If the car is not drivable
Activate the hazard warning flashers if the car has broken down or been forced to stop unexpectedly in a trafficked environment. Think about safety. If possible, move the car out of danger from traffic. Put on a reflective vest and then position the warning triangle so that other road users are warned in good time. Call roadside assistance.
