The concept
HDC is a downhill driving assistant that automatically controls vehicle speed on steep downhill gradients. Without the brakes being applied, the vehicle moves at slightly more than twice walking speed.
Hill Descent Control can be activated 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.
As long as there is active braking, the system is on standby. The system does not brake the vehicle during this time.
Use HDC in low gears or in transmission position D or R only.
