HILL HOLDER SYSTEM
This system is an integral part of the
ESC system and facilitates starting on
slopes.
It is automatically activated in the
following conditions:
❒uphill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
gearbox in neutral or gear (other than
reverse) engaged;
❒downhill: vehicle stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
reverse gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the torque
necessary for starting is reached, or
in any case for a maximum of 2
seconds, allowing your right foot to be
moved easily from the brake pedal to
the accelerator.
When two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage, the typical brake
disengagement noise indicating that the
vehicle is going to move imminently
will be heard.IMPORTANT The Hill Holder system is
not a parking brake; therefore, never
leave the vehicle without having
engaged the handbrake, turned the
engine off and engaged first gear,
so that it is parked in safe conditions
(for further information read the
"Parking" paragraph in the "Starting
and driving" chapter).
ASR (AntiSlip
Regulation) SYSTEM
It is an integral part of the ESC system.
It automatically operates in the event
of one or both drive wheels slipping,
loss of grip on wet roads (aquaplaning)
and acceleration on slippery, snowy
or icy roads, etc.
Depending on the slipping conditions,
two different control systems are
activated:
❒if the slipping involves both drive
wheels, the ASR intervenes reducing
the power transmitted by the engine;
❒if the slipping only involves one of the
drive wheels, it intervenes
automatically braking the wheel that
is slipping.
62)
Engagement/ disengagement of the
ASR system
The ASR system switches on
automatically each time the engine is
started.
Whilst driving, the ASR can be switched
off and subsequently switched on
again by pressing the ASR OFF button
fig. 125.
61)
On some versions, the intervention of
the system is indicated by a message
shown on the display.
When the system is not active, the LED
on the button ASR OFF turns on and,
on some versions, a message appears
on the display.
If the ASR is disengaged during driving,
it is automatically reactivated when
the vehicle is next started.
125F1A0324
83

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 Above 25 km/h the HDC
system deactivates but is still ready
to operate (the LED on the button
remains on) when the speed is again
below 25 km/h. If the speed exceeds
50 km/h, the HDC system deactivates
completely (the LED on the button
switches off) and the function does not
operate autonomously on the brakes
anymore. To reactivate it, press the
dedicated button again when the speed
is again below 25 km/h.
8)
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) The performance of the ESC and
ASR systems must not encourage
the driver to take unnecessary
risks. Driving style must always be
adapted to road conditions,
visibility and traffic. The driver is,
in any case, responsible for safe
driving.
62) For the ESC and ASR systems to
function correctly, all four tyres
must be the same brand and type,
must be in excellent condition
and, above all, must be of the
prescribed type and size.
63) 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.
64) The HBA system cannot prevent
accidents, including those due to
excessive speed on bends,
travelling on low-grip surfaces or
aquaplaning.
85

Traction Plus operation
The system is deactivated when
starting. To activate the Traction Plus
system, press button A fig. 127: the
LED on the button switches on.
The activation of the Traction Plus
system involves the following functions
being switched on:
❒inhibition of the ASR function, in
order to fully exploit the engine
torque;
❒the differential locking effect on the
front axle, through the braking
system, to improve traction
on irregular grounds.
If the Traction Plus system is faulty, the
warning light on the instrument
panel switches on constantly.When travelling on snowy roads with
snow chains, it may be helpful to turn
the Traction Plus on and thus inhibiting
the ASR function: in fact, in these
conditions, slipping of the drive wheels
when moving off makes it possible to
obtain better traction.
WARNING
67) The Traction Plus system acts
effectively only on road surfaces
that are not homogeneous and/or
differentiated between the two
drive wheels.
68) Until the setting off manoeuvre is
terminated, fully depress the
accelerator pedal in order to
transfer all the drive torque to the
wheel with the best grip.
TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
69) 70) 71) 72) 73) 74) 75) 76) 77)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the
vehicle.
Changes in outside temperature may
cause tyre pressure to vary. This means
that a decrease in the outside
temperature corresponds to a decrease
in the tyre pressure.
Tyre pressure must always be adjusted
according to the cold inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the vehicle stand
for at least three hours or a travel
shorter than 1.6 km after an interval of
three hours.
The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
127F1A0325
87

The tyre pressure also increases while
driving the vehicle: this is a normal
condition and does not require any
adjustment of the pressure.
The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
tyre low pressure control warning
light
switches on constantly, the
inflation pressure must be adjusted until
it reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. 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.
NOTE
❒The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒Therefore, the TPMS should not be
used as pressure switch while
adjusting the tyre inflation pressure.❒Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency
and tyre tread life and may also affect
handling and braking performance
of the vehicle.
❒The TPMS does not replace the
correct tyre maintenance. It is up to
the driver to maintain the correct tyre
pressure level measuring it with a
suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not
cause the tyre pressure control
warning light to switch on.
❒The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal
pressure loss of the tyre.
❒The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.WARNING Monitoring and maintaining
the correct pressure in all four tyres
are particularly important.
Tyre pressure
monitoring system low
pressure warnings
The system warns the driver if one or
more tyres are flat by switching on
the warning light
on the instrument
panel (together with a warning message
and an acoustic signal).
In this case, stop the vehicle as soon as
possible, check the inflation pressure
of each tyre and inflate to the cold tyre
pressure value prescribed for the
vehicle. The system will automatically
update and after receiving the tyre
pressure update the tyre pressure
control warning light switches off. You
may need to drive the vehicle for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.

KNOW YOUR VEHICLE

TPMS operation faults
The system fault is indicated by
warning light
which first flashes for
75 seconds and then stays on steadily.
This can occur in any of the following
situations:
❒interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.
❒Application of tinted films which
interfere with the signals of the radio
waves.
❒Presence of snow or ice on the
wheels or the wheel arches.
❒Use of snow chains.
❒Use of wheels/tyres not equipped
with TPM 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 switch on at the next
ignition cycle.❒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.IMPORTANT
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) 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.
89

OPERATION
The system is always active when the
vehicle is started. It can be deactivated
or re-activated by pressing button A
fig. 128 on the dashboard (see
following description).
The LED on the button switches on to
confirm that the system has been
activated and a dedicated message
appears on the display.
When the system is activated, the LED
on the dedicated button is off. If the
user deactivates the system, the LED
on the button switches on constantly
and a dedicated message appears
on the display to confirm that the
system has been switched off.The system is enabled at every key
cycle of the vehicle and starts
recognition of the operating conditions
(condition signalled to the driver when
the 2 direction warning lights
and
on the instrument panel light up).
When the system recognises the
operating conditions, it becomes active,
i.e. it can assist the driver with visual
and acoustic warnings. Therefore
the two direction warning lights
and
on the instrument panel switch off
to prevent excessively frequent
warnings while driving in towns or on
winding roads at low speeds.
IMPORTANT If the operating conditions
are no longer present, the system
remains activated but inactive.
Therefore the driver is warned by the 2
direction warning lights
andon
the instrument panel switching on
constantly.OPERATING CONDITIONS
FOR ACTIVATION
Once switched on, the system
becomes active only if the following
conditions are met:
❒front driving direction (reverse not
engaged);
❒the system does not detect any error;
❒calibration in progress;
❒vehicle speed between 60 km/h and
max. vehicle speed;
❒presence of lane demarcation lines
not deteriorated and visible on both
sides;
❒suitable visibility conditions;
❒straight line or wide radius bends;
❒sufficient field of vision condition
(safety distance from vehicle in front);
❒direction indicators not activated
in the lane exiting direction (e.g. right
lane exiting direction, right direction
indicator activated);
❒vehicle direction getting constantly
closer to the lane demarcation lines
(the vehicle trajectory is within the
lane demarcation lines);
❒vehicle not constantly next to the lane
demarcation line.

SYSTEM ACTIVATION/
DEACTIVATION
When the system is active, if the vehicle
gets close to one of the limit lines or
one of the two lane demarcation lines,
the driver is warned with an acoustic
signal (coming from the crossed line
side if the vehicle is equipped with the
radio navigation system) along with
the corresponding direction warning
light (
or) lighting up.
If the driver turns on the direction
indicator in order to change lanes or for
overtaking, then the system will switch
off the driver warning.
If the driver keeps deliberately with the
lane change manoeuvre, the system
interrupts the warning, remaining
enabled if the operating conditions are
not satisfied or active if the operating
conditions are exceeded (see the
dedicated paragraph).SWITCHING OFF THE
SYSTEM
Manual mode
The system can be switched off by
pressing button A fig. 128 on the
dashboard.
The LED on the button switches on and
a message appears on the display to
confirm that the system has been
switched off.
Automatic mode
If the Start&Stop is active the system
deactivates automatically. The system
will reactivate and check its operating
conditions again after the vehicle has
been started.
SYSTEM FAILURE
In the case of malfunction the system
signals the fault to the driver with a
message on the display, an acoustic
warning and switching on of the icon
on the display (for versions/markets,
where provided).IMPORTANT INFORMATION
The Driving Advisor cannot operate due
to a not perfectly balanced and
excessive load.
The operation of the system can be
adversely affected in some cases
by the morphology of the territory/road
being driven on (e.g. driving over
humps), poor visibility conditions (e.g.
fog, rain, snow), extreme light
conditions (e.g. glare of the sun,
darkness), lack of cleanliness
or damage, even partial, to the
windscreen in the area in front of the
camera.
The Driving Advisor cannot operate
following a malfunction of the following
safety systems: ABS, ESP, ASR and
Traction Plus.
The operation of the system can be
adversely affected by poor visibility
conditions (e.g. fog, rain, snow),
extreme light conditions (glare of the
sun, darkness), lack of cleaning or
damage, even partial, to the
windscreen in the area in front the
camera.
The area of the windscreen by the
camera must not be partly or totally
obscured by objects (e.g. stickers,
protective film, etc.).

The system displaying includes the
following two steps:
❒All new traffic signs that can be
recognised are displayed as pop-ups
for 40 seconds over the other
signallings.
❒After the preset time, they are
displayed in the dedicated screen on
the panel.
The system can display two traffic signs
(speed limit and no overtaking) at the
same time in the two dedicated areas
of the panel.If an additional traffic sign is detected,
e.g. a reduced speed limit for wet
road conditions, this is displayed as an
empty box under the relevant sign.
The additional signs are filtered as
follows:
❒The additional sign for "snow" or
"rain" will not be displayed if the
outside temperature is over 3°C.
❒The additional sign for "snow" or
"rain" or "cloudy" will not be
displayed if the windscreen wipers
are off and the outside temperature is
below 3°C.
❒The additional sign for "truck" will not
be displayed if the vehicle weighs
less than 4-4.5 t.
❒The speed limit sign will not be
displayed if coupled with the
additional "tractor" sign.

"ENERGY SAVING"
FUNCTION
(for versions/markets, where provided)
If, after the engine has been
automatically restarted, the driver does
not take any action for a period of
about 3 minutes, the Start&Stop
system will definitively stop the engine
to avoid fuel consumption. The engine
can only be started using the key in
such cases.
NoteIn any case, it is possible to keep
the engine running by deactivating
the Start&Stop system.
IRREGULAR OPERATION
In the event of malfunction, the
Start&Stop system is deactivated. The
driver is informed about the fault
through the switching on of the
icon
together with a message on the
display. In this case, contact a Fiat
Dealership.VEHICLE INACTIVITY
In the event of vehicle inactivity, special
attention must be paid to the
disconnection of the battery power
supply. Proceed as follows: detach
connector A fig. 134 (by pressing
