The concept
HDC is a downhill driving assistant that automatically controls vehicle speed on steep downhill gradients. Without requiring brake application, the vehicle moves at slightly more than twice walking speed.
You can activate the Hill Descent Control at speeds below approx. 22 mph/35 km/h. When driving downhill, the vehicle reduces its speed to approx. twice walking speed and then keeps its speed constant.
While you are actively braking, the system is on standby. The system does not brake the vehicle during this time.
