Driving -> Stop & Start for Your Citroen Ds4 SUV First Generation (2010-2018)

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.

lamp flashes for a few seconds, then
