SymbolWhat it means
yellowWATER IN DIESEL FILTER (Diesel versions)
The symbol switches on constantly while driving (along with a message in the display), to indicate the
presence of water in the diesel filter.
28)
yellow DPF CLEANING (particulate trap) in progress (diesel versions with DPF only)
The symbol switches on constantly to indicate that the DPF system needs to eliminate the trapped
pollutants (particulate) through the regeneration process.
The symbol does not switch on during every DPF regeneration, but only when driving conditions require
that the driver is notified. To turn off the symbol, keep the vehicle in motion until the regeneration process is
over. On average, the process lasts 15 minutes. Optimal conditions for completing the process are
achieved by travelling at 60 km/h with engine speed above 2000 rpm.
When this symbol switches on, it does not indicate a defect of the car and thus it should not be taken to a
workshop.

yellowENGINE OIL DETERIORATED
(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of 5 seconds until
the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue to switch on
as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply reports that it is
now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the car for short drives, preventing the engine from
reaching operating temperature.
Contact a Fiat Dealership as soon as possible.

WARNING
31)If, when the ignition device is turned to MAR, thewarning light does not switch on or stays on whilst driving, a failure may have
occurred in the restraint systems. In this case the airbags or pretensioners may not be deployed in an impact or, in a lower number of cases,
they may be deployed accidentally. Before continuing, contact a Fiat Dealership immediately to have the system checked.
32) The fault of the
warning light is signalled by the switching on of theicon on the instrument panel. In this case, the warning light may
not indicate any faults with the restraint systems. Before continuing, contact a Fiat Dealership immediately to have the system checked.
33) If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
IMPORTANT
24)If, turning the ignition device to MAR, thewarning light does not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact a Fiat Dealership as soon as possible.
25) If the warning light (or the icon on the display) flashes whilst driving, contact a Fiat Dealership.
26) If the symbol switches on when driving, stop the engine immediately and contact a Fiat Dealership.
27) Driving the vehicle with this symbol on may severely damage the gearbox, with resulting breakage. The oil may also overheat: contact with
hot engine or with exhaust components at high temperature could cause fires.
28) The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact a Fiat Dealership as soon as possible to bleed the system. If the above indications come on immediately after
refuelling, water has probably been poured into the tank: switch the engine off immediately and contact a Fiat Dealership.
29) Vehicle travel speed should always be adapted to the traffic and weather conditions, and must always comply with traffic regulations. The
engine can be stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason it is always advisable to wait for the symbol to go off before turning off the engine,
following the instructions above. Do not complete the DPF regeneration process when the vehicle is stopped.
30) If the
warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from
the first switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty.
Remember that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you do not need to top up
the engine oil.
31) If the symbol flashes when driving, contact a Fiat Dealership.

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.
