HDC Hill Descent Control
Concept
HDC is a downhill driving assistant that automati‐
cally controls vehicle speed on steep downhill
gradients. Without applying the brakes, the vehi‐
cle moves at slightly more than walking speed. It
the brakes are actively applied, the system dis‐
tributes force according to the traction.
Vehicle stability and maneuverability are im‐
proved on downhill gradients.
Hill Descent Control can be activated at speeds
below approx. 22 mph/35 km/h. When driving
downhill, the vehicle reduces its speed and then
keeps its speed constant.
Only use HDC in low gears or in selector lever
position D or R.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from approx.
4 mph/6 km/h to approx. 15 mph/25 km/h using
the rocker switch of the cruise control on the
steering wheel. Vehicle speed can be changed
by lightly accelerating.
▷ Press the rocker switch up to the point of re‐
sistance: the speed increases gradually.
▷ Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.
▷ Press the rocker switch down to the point of
resistance: the speed decreases gradually.
▷ Press the rocker switch down past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC
Press the button again. The LED goes out.
HDC is automatically deactivated above
approx. 37 mph/60 km/h.
