Stop & Start

The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in

the traffic (red lights, traffic jams, or other...). The engine restarts automatically - START mode - as

soon as you want to move off. The restart takes place instantly, quickly and silently.

Perfect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as

well as the noise level when stationary.
