Using the electronic rotary switch, the driver can choose between the three driving programs 'C' (Controlled Efficiency), 'S' (Sport) and 'S+' (Sport plus) and thus call up three different power levels of the electric motors. This also changes the top speed and the response of the accelerator pedal. The buttons for 'AMG Torque Dynamics' and 'AMG Setup' are located behind the buttons for 'Power' and 'ESP On/Off'.
