The Eco function optimises fuel consumption by reducing throttle response and limiting the performance of certain systems (such as the air conditioning). The core of this mode is the Start & Stop system, which shuts off the engine when the vehicle is stationary and restarts it when the brake (or clutch) is released.

There are two ways to activate/deactivate it: using the physical button with a green leaf on the centre console (press to activate and press again to deactivate), and via the display by entering the touchscreen menu, going to: vehicle settings and selecting "driving mode"; from here you can choose to select or deselect the "eco" mode.
