Engine Drag Control (EDC)
EDC helps keep the engine running if the wheels show a tendency to lock, e.g., when shifting down in the Geartronic manual shifting mode or while using the engine's braking function on a slippery surface. If the engine were to stop, power steering would not function, making the vehicle more difficult to steer.
