Get Driving -> Stop & Start Guide for Citroen Ds4 SUV Second Generation (2021-2025)

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.
