Hill Descent Control (HDC)
✓ Valid for vehicles: with 4Drive all-wheel drive
The HDC function is activated automatically
when driving down a steep hill in Offroad
mode.
Hill Descent Control limits speed on steep
downhill gradients by automatically braking all
four wheels, helping the driver to maintain pre-
cise control of the vehicle on off-road gradients
without having to constantly apply the brakes.
The system works in both forward and reverse,
even if the N position is selected on the gear-
box. Keeping the anti-lock brake system active
prevents the wheels from locking.
In vehicles with manual gearboxes, the Hill De-
scent Control adapts the theoretical speed
without braking the engine below its idling
speed.
Hill Descent Control is available when the dash
panel display shows the message

HDC is on, but is not acting because the re-
quired conditions are not met.
After starting the descent of a steep hill at
less than 30 km/h (18 mph) when the system
is on, the HDC will activate automatically if
neither the accelerator nor brake pedals are
depressed. The speed is limited to a minimum
of 2 km/h (1 mph) and a maximum of 30 km/h
(18 mph).
At any time, the driver can increase or decrease
the speed within the above-mentioned limit by
depressing the accelerator or the brake. The
function is then temporarily interrupted while
the speed is being regulated and then activa-
ted again if applicable.
However, it is essential that the surface ensures
sufficient grip. For this reason, the Hill Descent
Control will not fulfil its function when, for ex-
ample, descending a slope with a frozen or slip-
pery surface.
The Hill Descent Control intervenes automati-
cally if the following conditions are met:
●
The vehicle's engine is running.
●
The Offroad driving profile has been selec-
. ted. Driving at a speed below 30 km/h (18 mph)
(the message is shown on the dash panel
display).
●
The downward gradient is at least 10%.
●
Neither the brake nor accelerator pedal is de-
pressed.
Driving
The hill descent control is deactivated if the
gradient is less than 5%. The function can be
switched off manually in the infotainment sys-
tem using the > HDC function button.
WARNING
Always be ready to apply the brakes. Failure
to do so could result in an accident and in-
jury.
●
The hill descent control is only an auxiliary
system which in some situations may not be
able to brake the vehicle sufficiently when
going downhill.
●
The vehicle's speed may increase despite
the intervention of the hill descent control.
