If you experience an operational disruption or deviation from the car's normal function then it may be due to a fault or the specific circumstances of the situation.
Some functions have limitations in particular situations and 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 a situation.

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 if the cause cannot be remedied at your location.
