ECO start/stop function
Introduction
The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When the vehicle pulls away again, the engine
starts automatically. The ECO start/stop func-
tion thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
