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. 102; 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
58)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.
59)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
60)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.
61)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.

SAFETY
Presence of snow or ice on the
wheels or the wheel arches.
Use of snow chains.
Use of wheels/tyres not equipped
with TPMS sensors.
The space-saver wheel is not
equipped with the tyre pressure control
sensor. Therefore, the tyre pressure is
not controlled by the system.
If the space-saver wheel replaces a
tyre with a pressure lower than the
insufficient pressure limit, an acoustic
signal will be emitted and the
warning light will turn on at the next
start-up.
When the original tyre is repaired or
replaced and it is mounted back on
the vehicle to replace the space-saver
wheel, the TPMS will update
automatically and the warning light will
switch off, provided that the pressure of
none of the four tyres is below the
insufficient pressure limit. You may need
to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
WARNING
69)The TPMS is optimised for the original
tyres and wheels provided. TPMS
pressures and alerts have been defined
according to the size of the tyres mounted
on the vehicle. Using equipment with
different size, type or kind may cause
irregular system operation or sensor
damage. Non-original spare wheels can
damage the sensor. Do not use tyre
sealant or balancing weights if the vehicle
is equipped with TPMS as these may
damage the sensors.
70)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
71)The TPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not even to be
considered a replacing system for
maintenance or a safety system.
72)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
73)The TPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.74)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
75)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect your ability to drive the
vehicle safely.
76)Always refit the valve stem cap after
inspecting or adjusting tyre pressure. This
prevents dampness or dirt from entering
the valve stem and thus the pressure
control sensor from being damaged.
77)The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
TPMS sensors; using sealants not
equivalent with that in the original kit may
adversely affect its operation. If sealants
not equivalent with the original ones are
used, it is recommended to have the
TPMS sensor operation checked by a
qualified repair centre.
