Description and operation
Hill Descent Control limits the speed on steep
descents by aut
omatically br
aking all f
our
wheel
s, both when mo
ving forward and in re-
verse. As the anti-lock brake system remains
active, it prevents the wheels from locking. In
vehicles with manual transmission, the Hill
Descent Control adapts the theoretical
speed without slowing the engine below its
idling speed.
After starting the descent of a slope below
30 km/h (18 mph), speed is limited to a mini-
mum of 2 km/h (1 mph) and a maximum of
30 km/h (18 mph). When appropriate, the
driver may increase or decrease the speed
within the limit by pressing the accelerator or
the brake. At this point the function is interrup-
ted and, if necessary, it is then reactivated.
Even so, it is imperative that the surface guar-
antees sufficient adhesion. For this reason,
the Hill Descent Control will not fulfil its func-
tion when, for example, descending a slope
with a frozen or slippery surface.
Hill Descent Control is available when the
dash panel display shows the message .
Hill Descent Control automatically intervenes
if the following conditions are met:
●
The vehicle engine is running.
●
The Offroad driving profile has been selec-
ted
›››
page 261. Driving at a speed below
30 km/h (18 mph) (the message is shown
on the instrument panel).
●
The slope of the descent is at least 10%
when driving forward and 9% when driving in
reverse.
●
The brake and the accelerator are not
pressed.
Hill Descent Control is deactivated on press-
ing the brake and the accelerator or if the
slope is below 5%. The function may be dis-
connected manually in the Easy Connect
system by pressing the > HDC button.
WARNING
Always be ready to brake. Otherwise, an
accident could occur and cause injury.
●
Hill Descent Control is only an auxiliary
system that in some situations may not suf
-
ficiently brake the vehicle when going
down a slope.
●
The speed of the vehicle may increase
despite the intervention of Hill Descent
Control.
