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);
HHC (Hill Hold Control);
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.
34) 35) 36) 37) 38) 39) 40)
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.

SAFETY

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.
41) 42) 43) 44) 45)
TC (Traction Control)
SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on
one or more drive wheels. Depending
on the slipping conditions, two different
control systems are activated:
if the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine;
if the slipping only involves one of the
drive wheels, the BLD (Brake Limited
Differential) function is activated,
automatically braking the wheel which
is slipping (the behaviour of a
self-locking differential is simulated).
This will increase the engine torque
transferred to the wheel which isn't
slipping. This function remains active
even if the "Systems partially disabled"
and "Systems disabled" modes are
selected (see description in the
following pages). 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.
46) 47) 48) 49) 50)
PBA (Panic Brake
Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
completes the ABS.
Maximum assistance from the PBA
system is obtained by pressing the
brake pedal very quickly. In addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system. Do not reduce
pressure on the brake pedal until
braking is not necessary anymore.
The PBA system is deactivated when
the brake pedal is released.
51) 52) 53)
HHC (Hill Hold Control)
SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and
transmission 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 engine
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 it is possible to hear a
typical mechanical brake release noise,
indicating the imminent movement of
the vehicle.
54) 55)
75

DST SYSTEM (Dynamic
Steering Torque)
The DST function uses the integration
of the ESC system with the electric
power steering to increase the safety
level of the whole vehicle.
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.
56)
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.
57)
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.
58) 59)
WARNING
34) 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.
35) 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.
36) 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.
37) The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
38) The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
76
SAFETY

The acceptance by the system of the
requested driving mode is signalled by
the LED, located besides the symbol,
coming on, and by the corresponding
symbol appearing on the instrument
panel display.
When the engine is started, the system
usually maintains the driving mode that
was active before the engine was
stopped. For versions/markets where
provided, on start-up, the system is set
to the "Auto" mode.
"Auto" MODE
Recommended mode for normal
driving, aimed at comfort and safety in
normal grip and driving conditions. On
4x4 versions, this mode also reduces
fuel consumption, since it automatically
disconnects the transmission from the
rear wheels if the road and driving
conditions allow it, in addition to
changing drive torque distribution
between the front and rear axles.
Activation
Starting from the active "Traction/All
Weather" mode, turn the ring nut
anticlockwise, keeping it in this position
for at least half a second, and in any
case until the relevant LED turns on,
and the selected mode is shown on the
display. The LED for the previously set
mode will simultaneously turn off.Upon release, the ring nut will return to
the central position.
Starting from the active "Sport" mode,
turn the ring nut clockwise, keeping it in
this position for at least half a second,
and in any case until the relevant LED
turns on, and the selected mode is
shown on the display. The LED for the
previously set mode will simultaneously
turn off. Upon release, the ring nut will
return to the central position.
"Traction"/"All Weather"
MODE
It is a driving mode for safety in poor
vehicle grip conditions (wet/slippery
road surface, rain, snow). On the
4x4 versions use is also recommended
on unsurfaced roads or off-road.
Activation
Starting from the active "Auto" mode,
turn the ring nut clockwise, keeping it in
this position for at least half a second,
and in any case until the relevant LED
turns on, and the selected mode is
shown on the display. The LED for the
previously set mode will simultaneously
turn off. Upon release, the ring nut will
return to the central position.
Starting from the active "Sport" mode,
turn the ring nut anticlockwise, keeping
it in this position for at least half a
second, and in any case until the
relevant LED turns on, and the selected
mode is shown on the display. The LED
for the previously set mode will
simultaneously turn off. Upon release,
the ring nut will return to the central
position.
"Sport" MODE
It is the mode that emphasises the
pleasure of sport driving; it increases
fuel consumption however. Traction is
optimised on 4x4 versions, allowing the
vehicle road-hold performance to be
improved, even on bends.
Activation
Starting from the active "Auto" mode,
turn the ring nut anticlockwise, keeping
it in this position for at least half a
second, and in any case until the
relevant LED turns on, and the selected
mode is shown on the display. The LED
for the previously set mode will
simultaneously turn off. Upon release,
the ring nut will return to the central
position.

STARTING AND DRIVING

WARNING
132)Parking and other potentially
dangerous manoeuvres are, however,
always the driver’s responsibility. When
performing these operations, always make
sure that there are no other people
(especially children) or animals on the route
you want to take. The parking sensors are
an aid for the driver, but the driver must
never allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
IMPORTANT
65) The sensors must be clean of mud,
dirt, snow or ice in order for the system to
operate correctly. Be careful not to scratch
or damage the sensors while cleaning
them. Avoid using dry, rough or hard
cloths. The sensors should be washed
using clean water with the addition of car
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than
10 cm away.
66) Have interventions on the bumper in
the area of the sensors carried out only by
a Fiat Dealership. Interventions on the
bumper that are not carried out properly
may compromise the operation of the
parking sensors. 67)
Only have the bumpers repainted or
any retouches to the paintwork in the area
of the sensors carried out by a Fiat
Dealership. Incorrect paint application
could affect the operation of the parking
sensors.
68) The sensors may provide a false
indication, interpreting the tow hook ball
assembly and the relevant attachment as
an obstacle in the area behind the vehicle.
LANE ASSIST
SYSTEM (lane
crossing warning)
DESCRIPTION
69) 70) 71) 72) 73) 74)
The Lane Assist system makes use of a
camera located on the windscreen to
detect the lane limits and calculate the
position of the vehicle within such limits,
in order to make sure that it remains
inside the lane.
When both limits of the lane are
detected and the vehicle crosses one of
them without the awareness of the
driver (direction indicator off), the Lane
Assist system provides a tactile warning
by applying torque to the steering wheel
(vibration), thus advising the driver that
he must take an action to remain in the
lane.
IMPORTANT The torque applied to the
steering wheel by the system is
sufficient for the driver to notice it, but
always limited, so that they can easily
override it, and the driver always
maintains control of the vehicle. The
driver can therefore turn the steering
wheel as required at all times.
