KNOWING THE INSTRUMENT PANEL

ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
DTC (Drag Torque Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
DST (Dynamic Steering Torque);
ERM (Electronic Rollover Mitigation);
TSC (Trailer Sway Control).
For the operation of the systems, see
the following description.
ABS (Anti-lock Braking
System)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.The system also improves control and
stability of the vehicle when braking on
a surface where the grip of the left and
right wheels varies, or on corners.
The Electronic Braking Force
Distribution (EBD) system completes
the system allowing the brake force to
be distributed between the front and
rear wheels.
System intervention
The driver can feel that the ABS system
has come into action because the
brake pedal pulsates slightly and the
system gets noisier: this is entirely
normal with the system operating.
31) 32) 33) 34) 35) 36) 37)
DTC (Drag Torque
Control) SYSTEM
The DTC (Drag Torque Control) system
prevents the drive wheels from possibly
locking, which could happen, for
example, if the accelerator pedal is
released suddenly or in the case of a
sudden downshifting in conditions of
poor grip. In this conditions, the engine
braking effect could cause the drive
wheels to slip, resulting in a loss of car
stability. In these situations, the DTC
system intervenes, restoring torque to
the engine in order to conserve car
stability and increase car safety.
ESC (Electronic Stability
Control) SYSTEM
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the wheels
appropriately. The torque supplied by
the engine can also be reduced in order
to maintain control of the vehicle.
The ESC system uses sensors installed
on the vehicle to determine the
trajectory that the driver intends to
follow and compares it with the
vehicle’s effective trajectory. When the
real trajectory deviates from the desired
trajectory, the ESC system intervenes to
counter the vehicle’s understeer or
oversteer.
Oversteer: occurs when the vehicle is
turning more than it should according
to the angle of the steering wheel.
Understeer: occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
75
38) 39) 40) 41) 42)

In critical situations (braking on surfaces
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
53)
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll
over if the phenomenon is due to
reasons such as driving on high side
gradients, collision with objects or other
vehicles.
54)
TSC (Trailer Sway
Control) SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and
take the necessary precautions to
eliminate it.
To counteract the effect of trailer sway,
the system can reduce the engine
power and intervene on the wheels
involved. The TSC system activates
automatically once excessive sway of
the trailer is detected.
System intervention
When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.
55) 56)
WARNING
31)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on
the current road conditions.32)To obtain the maximum efficiency of
the braking system, a bedding-in period of
about 500 km is needed: during this period
it is better to avoid sharp, repeated and
prolonged braking.
33)If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
34)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
35)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
36)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
37)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
38)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
39)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40)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.

DRIVING
ASSISTANCE
SYSTEMS
The vehicle can feature the following
driving assistance systems:
BSA (Blind Spot Assist);
FBC (Full Brake Control);
iTPMS (indirect Tyre Pressure
Monitoring System).
For the operation of the systems, see
the following pages.
BSA (Blind-Spot Assist)
SYSTEM
The car can be equipped with the BSA
(Blind Spot Assist) system for blind spot
monitoring. The BSA system uses two
radar sensors, located in the rear
bumper (one for each side - see
fig. 55 ), to detect the presence of cars
(cars, trucks, motorbikes, etc.) in the
rear side blind spots of the car.The system warns the driver about the
presence of cars in the detection area
by lighting up, on the relevant side, the
warning light located on the door mirror
fig. 56, along with an acoustic warning.
As soon as the ignition key is in MAR
position, or when the engine is started
(keyless version), the warning light turns
on to signal the driver that the system is
active.Sensors
The sensors are activated when any
forward gear is engaged at a speed
higher than about 10 km/h, or when
reverse is engaged.
The sensors are temporarily deactivated
with car at a standstill and the gear
lever in position P (Park) (versions with
automatic transmission), or with car at a
standstill and electric parking brake
engaged (versions with manual
transmission).
The detection area of the system
covers about a lane on both sides of
the vehicle (around 3 metres).
This area starts from the door mirror
and extends for about 6 metres
towards the rear part of the car.
When the sensors are active the system
monitors the detection areas on both
sides of the car and warns the driver
about the possible presence of cars in
these areas.
While driving the system monitors the
detection area from three different input
points (side, rear and front) to check
whether a signal needs to be sent to
the driver. The system can detect the
presence of a vehicle in one of these
three areas.

accident, but permits more dynamic
driving of the car.
With the system sensitivity set to "Far",
the system will warn the driver of a
possible accident with the vehicle in
front when that vehicle is at a greater
distance, thus providing the possibility
of acting on the brakes more lightly and
gradually. This setting provides the
drivers with the maximum possible
reaction time to prevent a potential
accident.
Changing the setting to “Med”, the
system warns the driver of a possible
accident with the vehicle in front when it
is at a standard distance, between that
of the other two settings. This setting
offers an intermediate reaction time to
the driver with respect to those of the
"Near" and "Far" settings.
The system sensitivity setting is kept in
the memory when the engine is
switched off.
System limited operation signal
If the dedicated message is displayed,
a condition limiting the system
operation may have occurred. The
possible reasons of this limitation are
something blocking the camera view or
a fault.
If an obstruction is signalled, clean the
area of the windscreen indicated infig. 58 and check that the message has
disappeared.
Although the car can still be driven in
normal conditions, the system may be
not completely available.
When the conditions limiting the system
functions end, this will go back to
normal and complete operation. Should
the fault persist, contact a Fiat
Dealership.
System failure warning
If the system switches off and a
dedicated message is shown on the
display, it means that there is a fault on
the system.
In this case, it is still possible to drive
the vehicle, but you are advised to
contact a Fiat Dealership as soon as
possible.
Radar indication not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display. This
generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The system can also be temporarily
dimmed due to obstructions such as
mud, dirt or ice on the bumper. In such
cases, a dedicated message will be
shown on the display and the systemwill be deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow). When the
conditions limiting the system functions
end, this will go back to normal and
complete operation.
In certain particular cases, this
dedicated message could be displayed
when the radar is not detecting any
vehicles or objects within its view range.
If atmospheric conditions are not the
real reason behind this message, check
if the sensor is dirty. It could be
necessary to clean or remove any
obstructions in the area shown in
fig. 57.
If the message appears often, even in
the absence of atmospheric conditions
such as snow, rain, mud or other
obstructions, contact a Fiat Dealership
for a sensor alignment check.
In the absence of visible obstructions,
cleaning the radar surface, by manually
removing the decorative cover trim,
could be required. For this operation,
contact a Fiat Dealership.
IMPORTANT It is recommended that
you do not install devices, accessories
or aerodynamic attachments in front of
the sensor or darken it in any way, as
this can compromise the correct
functioning of the system.

DESCRIPTION
The Adaptive Cruise Control (ACC) is a
driver assist device which combines the
Cruise Control functions with one for
controlling the distance from the vehicle
ahead.
The Adaptive Cruise Control (ACC) uses
a radar sensor, located behind the front
bumper fig. 98 and a camera, located
in the middle of the windscreen fig. 99,
to detect the presence of a vehicle
close ahead.There are two operating modes:
“Adaptive Cruise Control”mode
to maintain an adequate distance
between vehicles (the message
“Adaptive Cruise Control” is shown on
the instrument panel display);
electronic “Cruise Control” mode
to hold the vehicle at a constant
preset speed.
To change the operating mode, use the
button on the steering wheel (see that
described on the following pages).

the one ahead. In this case the speed
will be determined only by the position
of the accelerator pedal.
The device will return to normal
operation as soon as the accelerator
pedal is released.
The systemcannotbe set
when pressing the brake pedal;
when the brakes are overheated;
when the electric parking brake is
engaged;
when the shift lever is in the P (park),
R (reverse) or N (neutral) positions
(versions with automatic transmission or
automatic transmission with double
clutch);
when the shift lever is in the R
(reverse), neutral or in 1st(first gear
engaged) positions (versions with
manual transmission);
when the clutch is pressed (versions
with manual transmission);
when the engine speed exceeds a
maximum threshold (versions with
manual transmission and versions with
automatic transmission/automatic
transmission with double clutch) or
goes below a minimum threshold (only
versions with manual transmission);
when the car speed is not within the
settable speed range;
when the ESC (or ABS or other
stability control systems) are operating
or have just operated;

STARTING AND DRIVING

1-bar setting) to 2 seconds (for the
maximum distance 4-bar setting).
The setting is 4 (maximum) the first time
the device is used. After the distance
has been modified by the driver, the
new distance will be stored also after
the system is deactivated and
reactivated.
To decrease the distance
Press and release the
button to
decrease the distance setting.
The distance setting decreases by one
bar (shorter) every time the button is
pressed.
The set speed is held if there are no
cars ahead. Once the shortest distance
has been reached, a further press of
the button will set the longest distance.
The car holds the set distance until:
the vehicle ahead accelerates to a
speed higher than the set speed;
the vehicle ahead leaves the lane or
the detection field of the Adaptive
Cruise Control device sensor;
the distance setting is changed;
the Adaptive Cruise Control device is
deactivated/cancelled.
IMPORTANT The maximum breaking
applied by the device is limited. The
driver may apply the brakes in all cases
if needed.IMPORTANT If the device predicts that
the braking level is not sufficient to hold
the set distance, the driver is warned by
a message indicating that the vehicle
ahead is too close appears on the
display. An acoustic warning is also
emitted. In this case, it is advisable to
brake immediately as necessary to hold
a safe distance from the vehicle ahead.
IMPORTANT The driver is responsible
for ensuring that there are no
pedestrians, other cars or objectives
along the direction of the car. Failure to
comply with these precautions may
cause serious accidents and injuries.
IMPORTANT The driver is fully
responsible for holding a safe distance
from the vehicle ahead respecting the
highway code in force in the respective
country.
DEACTIVATION
The device is deactivated and the set
speed is cancelled if:
thebutton is pressed on the
Adaptive Cruise Control;
thebutton is pressed on the
electronic Cruise Control;
the Speed Limiter button is pressed;
the ignition device is in the STOP
position.
The device is cancelled (the set speed
and distance are stored):
when the CANC button is pressed;
when the conditions shown in the
“Setting the desired speed” paragraph
occur;
when the car speed drops under the
minimum set speed (e.g. in presence of
slow cars).
If these conditions occur while the
system is decelerating with respect to a
vehicle ahead, the system could
continue the deceleration, if necessary,
also after it is cancelled or deactivated
within the minimum speed settable on
the system.
ELECTRONIC CRUISE
CONTROL MODE
Electronic Cruise Control mode is
available for travelling at constant speed
in addition to the Adaptive Cruise
Control (ACC) mode.
If the Adaptive Cruise Control (ACC)
function is implemented on the vehicle,
the electronic Cruise Control works in
the same manner as the ACC (by
pressing the
button of the Cruise
Control) with the difference that:
it does not hold the distance from the
vehicle ahead;
the device keeps working if the radar
sensor is obstructed.
Before returning to the previously set
speed, bring the speed close to that
value, then press the RES button and
release it.
