With the start/stop function, the engine switches off temporarily when the car has stopped e.g. at traffic lights or in a traffic queue, and then starts again when it is needed.
Activating and deactivating the start/stop function
The start/stop function is available when the car is started. When the function is activated, the engine is switched off temporarily. The engine then starts automatically when the function is deactivated or when the car requires this.
