Zusammenfassung:	The method involves determining state quantities (40), where the state quantities are assigned to predesignated parameters for automatic shutdown of a combustion engine. Determination is made to find whether automatic shutdown of the combustion engine is made available (50) based on the determined state quantities. Information are output (60) using an optical display device i.e. touch screen, when the automatic shutdown of the combustion engine is made available for all predetermined parameters, where the display device is arranged in a region of a combination instrument. The state quantities are selected from a group comprising momentarily inserted gears of a gear box, a position of clutch pedals, a state of charge of an energy storage device, an operating mode of an air conditioning apparatus, momentary external temperature, intake air temperature, coolant temperature, an operating mode of stop/start system, a low pressure value of a brake booster, an aperture state of a vehicle door, an aperture state of a bonnet and an aperture state of one of the seat harness release of a motor car. The predetermined parameters are selected from a group comprising an idle position of a gear shift lever, loosening of the clutch pedals, a state of charge of the energy storage device over a predetermined threshold, temperature condition and an activated state of stop/start system. Independent claims are also included for the following: (1) a stop/start system (2) a motor car (3) a computer program product comprising a set of instructions for operating a stop/start system of a combustion engine of a motor car (4) a machine-readable medium having a set of instructions operating a stop/start system of a combustion engine of a motor car. Ein Gegenstand der Anmeldung betrifft ein Verfahren zum Betreiben eines Stopp/Start-Systems (1) eines Verbrennungsmotors (2) eines Kraftfahrzeugs (3). Das Stopp/Start-System (1) ist zum automatischen Abschalten des Verbrennungsmotors (2) ausgebildet. Das Verfahren weist folgende Schritte auf. Es erfolgt ein Ermitteln von Zustandsgrößen, wobei die Zustandsgrößen zu vorbestimmten Parametern für ein automatisches Abschalten des Verbrennungsmotors (2) zugeordnet sind. Zudem erfolgt ein Ermitteln, ob ein automatisches Abschalten des Verbrennungsmotors (2) möglich ist, basierend auf den ermittelten Zustandsgrößen. Weiterhin erfolgt ein Ausgeben von Informationen, ob ein automatisches Abschalten des Verbrennungsmotors (2) möglich ist, für sämtliche
