Use the ECO position for maximum vehicle range and for city driving. The ECO position helps reduce power consumption by reducing acceleration when compared to the same accelerator pedal position in the D (Drive) position and reduces the power provided to the heating and air conditioner system. Without navigation system model: When the ECO position is used, more regenerative brake is applied when the accelerator pedal is released in comparison to the D (Drive) position. NOTE: The regenerative brake converts the vehicle's forward motion to electric power to help slow the vehicle. While the vehicle is being driven you can check your own ECO drive level on the ECO indicator. See ЉECO indicatorЉ in the ЉInstruments and controlsЉ section. EV Overview EV-19
