BMW 3: System components
The front radar sensor (FRS) or the front radar sensor long range (FRSF) is needed to reliably detect the vehicles in front. Consequently, adaptive recuperation is only possible with the optional equipment Active Cruise Control with Stop&Go function (SA 5DF).
Adaptive recuperation can be implemented on different control units. Depending on the equipment specification, the function is integrated in the control unit optional equipment system SAS (with Driving Assistant Professional (SA 5AU)) or in the DSC control unit (Active Cruise Control with Stop&Go function (SA 5DF) ).

Operation of the brake pedal is recorded and processed directly by the DSC unit.
The Digital Motor Electronics (DME) assumes the central coordination between the setpoint torque specifications which are output by the different control units. The higher torque request is then forwarded to the EME for implementation. The DME also stores the driving modes in which the function is available and not available.

Climate Control
As in previous BMW hybrid vehicles, an electrically powered air conditioning
compressor is used in
the G20 PHEV. Because the A/C compressor has an electric motor, it is possible

General information
Do not use the wipers if the windshield is dry, as
this may damage the wiper blades or cause them
to become worn more quickly.
