The ECO start/stop function is only available for the S 63 AMG.

The ECO start/stop function is only available in drive program C.

The ECO start/stop function switches the engine off automatically when the vehicle stops moving.

The engine starts automatically when the driver wants to pull away again. The ECO start/stop function thereby helps you to reduce the fuel consumption and emissions of your vehicle.

The ECO start/stop function is activated each time the engine is switched on. If all the requirements are fulfilled for automatic engine switch-off, the green ECO symbol is shown in the multifunction display and Stop/Start active appears. If not all of the requirements are fulfilled, the ECO symbol is shown in yellow and Stop/Start inactive appears.

If the ECO start/stop function is deactivated, the symbol is not shown.

WARNING

You could suffer serious or even fatal injury or cause an accident resulting in injury or death.
