Hill Descent Control HDC
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. The vehicle moves at approxi‐
mately 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.
Increasing or reducing speed
The speed can be changed in the range from
approx. 4 mph/6 km/h to ap‐
prox. 15 mph/25 km/h by pressing the acceler‐
ator or brake pedal lightly.
A target speed within the same range can be
specified using the lever of the cruise control.
On inclines over 10 %, you can reduce the speed
to approx. 3 mph/4 km/h. Pull the lever of the
cruise control beyond the resistance point, ar‐
row 3.
1 Increasing speed
2 Pull to the resistance point: reduce the
speed to approx. 4 mph/6 km/h
3 Pull beyond the resistance point: on inclines
over 10 %, reduce the speed to ap‐
prox. 3 mph/4 km/h
Activating HDC
Press the button; the LED above the button
lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again; the LED goes out. HDC
is automatically deactivated above approx.
37 mph/60 km/h.
