The concept

HDC is a downhill driving assistant that automatically controls vehicle speed on steep downhill gradients. The vehicle moves at approximately walking speed without braking intervention by the driver.

You can activate the Hill Descent Control at speeds below approx. 22 mph/35 km/h. When moving downhill at speeds below approx.

22 mph/35 km/h, the vehicle reduces its speed to approximately walking speed, approx. 5 mph/ 8 km/h and keeps it constant.

Only use HDC in transmission positions D or R.
