The start-stop system automatically switches off the engine when the car is stopped, for example at traffic lights, and starts it automatically when the journey continues.
This is how it works: brake the car down to a standstill, shift into neutral and release the clutch. The system now switches off the engine and signals this via an indicator lamp. Depress the clutch before continuing the journey – the engine now starts automatically and the indicator lamp goes out again.
