HILL DESCENT CONTROL
(HDC) SYSTEM
It is an integral part of the ESC and is
aimed at keeping the vehicle at a
constant speed during a descent,
operating autonomously on the brakes
in various ways at the same time. In this
way the vehicle stability and completely
safe driving are guaranteed, above all
in poor grip conditions and/or steep
descents.
To activate the system, reach a speed
slower than 25 km/h and press the
corresponding button A fig. 83; the LED
on the button turns on and the display
shows a dedicated message.
After reaching the desired speed,
release the accelerator and brake
pedals completely (the LED on the
button flashes). If you want to
increase/decrease the speed, press the
accelerator/brake pedals again.
IMPORTANT Do not use the device
with the gearbox in neutral position.
IMPORTANT It is important to engage a
gear suitable for the set speed, to
prevent the engine from stalling.
When this function is active the brake
lights turn on automatically.
While the HDC system is operating it is
also possible to take control of the
vehicle again by pressing the brake and
accelerator pedals.
If the function is not made available
when the button is pressed, this could
be due to brake overheating. In this
case, wait a few minutes before using
the function again.
IMPORTANT The system is available for
speeds below 25 km/h.
IMPORTANT On exceeding 25 km/h,
the HDC system is disabled and
remains ready to operate again (the
LED on the button remains on) when
the vehicle returns below 25 km/h.
If the vehicle speed exceeds 50 km/h,
the HDC system turns off completely
(the LED on the button turns off) and
any autonomous action on the brakes
is disabled. To reactivate it, press the
dedicated button again when the speed
is again below 25 km/h.

WARNING
57) The ESC system can’t overrule the
natural laws of physics, and can’t increase
the grip available according to the
condition of the road.
58) The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
59) The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.
60) For the correct operation of the ESC
and ASR system it is vital that the tyres are
the same make and the same type on all
the wheels, in perfect condition and, above
all, the recommended type and size.
61) The performance of the ESC and ASR
systems must not encourage the driver
to take unnecessary risks. Driving style
must always be suitable for road
conditions, visibility and traffic. The driver
is, in any case, responsible for safe driving.
62) The HBA system cannot increase
tyre grip on the road over the limits
imposed by laws of physics: always drive
carefully according to the conditions of the
road surface.
63) The HBA system cannot prevent
accidents, including those due to excessive
speed on bends, travelling on low-grip
surfaces or aquaplaning.
