Start/Stop
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 automatically when the journey is resumed.
Start/Stop is one of several energy-saving functions intended to reduce fuel consumption, which in turn helps to reduce exhaust emissions.
The system makes it possible to adopt an environmentally-conscious driving style by allowing the car to engine auto-stop when possible.
