Hill Descent Control (HDC)*
HDC can be compared to an automatic engine brake. When you release the accelerator on downhill gradients the car is normally braked by means of the engine striving for low engine idling speeds, so-called engine braking. But the steeper the roadway and the more load in the car, the faster the car coasts despite engine braking - the HDC function compensates for this with automatic brake intervention.
The function of the radar sensor is to detect cars or larger vehicles in the same direction, in the same lane.
Adjustable steering force*
Speed related power steering causes the steering wheel force to increase with the speed of the car in order to give the driver enhanced sensitivity.
