As part of recuperation energy is recovered during vehicle deceleration. For example, the battery charges when going downhill, instead of losing the energy when braking in the form of heat. You can set the strength of recuperation in 5 stages using the steering wheel shift paddles: D+ (0 m/s²), D (-0.5 m/s²), D- (-1.0 m/s²), D-- (-1.5 m/s²). In the "D Auto" recuperation setting, the ECO Assistant system is activated automatically to help you use the battery charge most effectively. It automatically matches the recuperation level to the driving situation.
