The following system functions are described for the DSC:
- DTC: Dynamic Traction Control
- Brake standby through application at an early stage of the brake pads when required
- Dry braking of the brake discs on wet roads
- Fading compensation
- Drive-off assistant
- Cruise control (calculated in the ICM) with braking function
- ABS: Antilock braking system
- EBV: Electronic brake force distribution
- CBC: Cornering brake control
- MSR: Engine drag torque control
- ASC: Automatic Stability Control
- DSC: Dynamic Stability Control
- DBC: Dynamic Braking Control
- HDC: Hill Descent Control
- xDrive: Four-wheel drive
- Performance Control
- ADB-X: Automatic differential brake on all-wheel drive vehicles
- Automatic Hold
- Dynamic emergency braking
- Trailer Stability Control
The following additional functions that do not belong to driving dynamics control are integrated:
- RPA: Run Flat Indicator
- CBS: Condition Based Service (only scope of maintenance work for brake pad wear)
