REFUELLING
Petrol engines: only refuel with unleaded petrol with octane rating (RON) not less than 95 in compliance with the European specification
EN228.Diesel engines: only refuel with diesel fuel conforming to the European specification EN590. The use of other products or mixtures
may damage the engine beyond repair and consequently invalidate the warranty, due to the damage caused.
STARTING THE ENGINE
Petrol engines: make sure that the handbrake is engaged; set the gear lever to neutral; fully depress the clutch pedal without pressing the
accelerator, then turn the ignition key to AVV and release it as soon as the engine has started.Diesel engines: turn the ignition key to MAR
and wait for the
andwarning lights to switch off. Then turn the ignition key to AVV and release it as soon as the engine has started.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park on grass, dry leaves, pine needles or other flammable
material: fire hazard.
RESPECTING THE ENVIRONMENT
The vehicle is fitted with a system that allows continuous diagnosis of the emission-related components in order to help protect the
environment.
ELECTRICAL ACCESSORIES
If, after buying the vehicle, you decide to add electrical accessories (with the risk of gradually draining the battery), visit a Fiat Dealership. They
can calculate the overall electrical requirement and check that the vehicle's electrical system can support the required load.
SCHEDULED SERVICING
Correct maintenance enables the vehicle to perfectly maintain performance and safety characteristics, its environmental friendliness and low
running costs over time.

WARNING
1)Used batteries are harmful to the
environment. You can dispose of them
either in the correct containers as specified
by law or by taking them to a Fiat
Dealership, which will deal with their
disposal.
IGNITION DEVICE
The key can be turned to 3 different
positions fig. 10:
STOP: engine off, key extractable,
steering locked. Some electrical
devices (e.g. sound system, central
door locking system, etc.) can operate;
MAR: driving position. All electrical
devices are enabled;
AVV: engine starting (unstable
position).
The ignition switch is fitted with an
electronic safety system that requires
the ignition key to be turned back
to STOP if the engine will not start,
before the starting operation can be
repeated.

“Smart washing” function
Pull the stalk towards the steering
wheel (unstable position) to operate the
windscreen washer.
Keeping the stalk pulled for more than
half a second, with just one movement
it is possible to operate the washer
jet and the wiper at the same time.
The windscreen wiper stops working
three strokes after the stalk is released.
A further stroke after approximately 6
seconds completes the cycle.REAR WINDOW
WIPER/WASHER
This operates only with the ignition key
turned to MAR.
Activation
Turn the ring nut to
to operate the
rear window wiper:
in intermittent mode when the
windscreen wiper is not operating;
in synchronous mode (at half the
speed of the windscreen wiper) when
the windscreen wiper is operating;
in continuous mode with reverse
gear engaged and the control active.
With the windscreen wiper on and
reverse gear engaged, rear window
wiping will be continuous.
Pushing the stalk towards the
dashboard (unstable position) will
activate the rear window washer jet.
Keep the stalk pushed for more than
half a second to activate the rear
window wiper as well. Releasing the
stalk will activate the smart washing
function, as described for the
windscreen wiper.
The function stops when the stalk is
released.
5)
HEADLIGHT WASHERS
(for versions/markets, where provided)
They are activated when the dipped
headlights are on and the windscreen
washer is activated.
IMPORTANT Check jet function and
cleanliness at regular intervals.
6)
WARNING
3)Do not use the windscreen wiper to
remove layers of snow or ice from the
windscreen. In such conditions, the
windscreen wiper may be subjected to
excessive stress and the motor cut-out
switch, which prevents operation for a few
seconds, may intervene. If operation is
not restored (even after turning the key and
restarting the engine), contact a Fiat
Dealership.
4)Do not operate the windscreen wiper
with the blades lifted from the windscreen.
5)Do not use the rear window wiper to
remove layers of snow or ice. In such
conditions, the wiper may be subjected to
excessive stress and the motor protection,
which prevents operation for a few
seconds, may intervene. If operation is not
restored, contact a Fiat Dealership.
6)The headlamp washer jet does not
function when the level of fluid in the
reservoir falls below 1.6 litres.

SPEEDOMETER
This shows the speed at which the
vehicle is travelling.
REV COUNTER
The rev counter shows the engine rpm.
IMPORTANT The electronic injection
control system gradually shuts off
the flow of fuel when the engine
is “over-revving” resulting in a gradual
loss of engine power.
When the engine is idling, the rev
counter may indicate a gradual or
sudden increase of the speed.
This behaviour is standard as it takes
place during the activation of the
climate control system or the fan. It
should not be considered as a fault. In
such cases, a slight increase in engine
idle speed helps to sustain the battery
charge.
FUEL LEVEL GAUGE
This shows the amount of fuel left in the
fuel tank.
E tank empty.
F tank full (see the instructions provided
in the “Vehicle refuelling” paragraph).
The warning light on the gauge comes
on to indicate that approximately 8-10
litres of fuel are left in the tank.
Do not travel with the fuel tank almost
empty: any gaps in fuel supply could
damage the catalytic converter.IMPORTANT The needle will point to E
and warning light A will flash to indicate
a fault in the system. Contact a Fiat
Dealership to have the system
checked.
ENGINE COOLANT
TEMPERATURE
INDICATOR
This shows the temperature of the
engine coolant fluid and starts working
when the fluid temperature exceeds
approx. 50°C.
In normal usage, the needle should
hover around the middle of the scale.
C Low engine coolant temperature.
H High engine coolant temperature.
The warning light on the gauge may
light up (and a message on the
multifunction display may appear on
certain versions) to indicate that the
coolant fluid temperature is too high; in
this case, stop the engine and contact
a Fiat Dealership.
10)
WARNING
10)If the needle for the engine coolant
temperature reaches the red area, stop the
engine immediately and contact a Fiat
Dealership.
DIGITAL DISPLAY
STANDARD SCREEN
The standard screen fig. 117 shows the
following information:
AHeadlamp alignment position (only
with dipped headlamps on).
BMilometer (distance covered in km or
miles).
CTime (always displayed, even with the
key extracted and the front doors
closed).
DStart&Stop function indication (for
versions/markets, where provided).
EGear Shift Indication (for versions/
markets, where provided).
NoteWith key removed (when opening
at least one of the front doors) the
display turns on and shows the time
and distance covered for a few
seconds.

KNOWING THE INSTRUMENT PANEL

EOBD SYSTEM
47)
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis
of emission-related components on
the vehicle to be made. It also alerts the
driver, by turning on warning light
in the instrument panel (together
with the relevant message in the display
on some versions), when these
components are no longer in peak
condition (see "Warning lights and
messages" section).
The goal of the system is to:
monitor the efficiency of the system;
indicate an increase in emissions
due to vehicle malfunction;
indicate the need to replace
components which have deteriorated.
The system also has a connector
that can be interfaced with appropriate
equipment, which makes it possible
to read the error codes stored in the
control unit together with a series
of specific parameters for engine
operation and diagnosis.
This check can also be carried out by
traffic control authorities.
IMPORTANT After eliminating the
failure, to check the system completely,
Fiat Dealerships run a bench test and,
if necessary, road tests which may
also call for a long journey.
WARNING
47)If, when the ignition key is turned to
MAR, thewarning light does not
switch on, switches on constantly or
flashes when driving (on certain versions
together with the message on the display),
contact a Fiat Dealership as soon as
possible. The operation of
warning
light may be checked by the traffic police
using specific devices. Always comply with
the traffic regulations in force in the
country where you are driving.

panelWhat it means What to do
redSEAT BELTS REMINDER
(for versions/markets, where provided)
The warning light switches on constantly with the
vehicle stationary and the driver's side or passenger
side seat belt (in versions where provided) not fastened.
The warning light flashes and a buzzer will sound if the
car is in motion and the driver’s seat belt is not correctly
fastened.For permanent deactivation of the acoustic signal
(buzzer) of the SBR. (Seat Belt Reminder) system
contact a Fiat Dealership.
Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light comes on when the ignition key
is turned to MAR, but should go off after a few
seconds. The warning light turns on when the
engine is overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off the engine
and check that the water level in the reservoir is not below the
MIN mark. In this case, wait for the engine to cool down, then
slowly and carefully open the cap, top up with coolant and
check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks. If,
when restarting, the warning light switches on again, contact a
Fiat Dealership.
If the vehicle is used under demanding conditions (e.g. in
high-performance driving): slow down and, if the warning light
stays on, stop the vehicle. Wait for 2 or 3 minutes with the
engine running and slightly accelerated to further favour the
coolant circulation. Then stop the engine. Check that the
coolant level is correct as described above.
IMPORTANT Over demanding routes, it is advisable to keep
the engine on and slightly accelerated for a few minutes before
switching it off.

Warning lights on
panelWhat it means What to do
redLOW ENGINE OIL PRESSURE
When the key is turned to MAR, the digital warning light switches on, but it should
switch off as soon as the engine is started.
The warning light switches on constantly together with the message in the display
when the system detects that the engine oil pressure is insufficient.
12)
DECAYED ENGINE OIL
(MultiJet versions with DPF only)
The warning light starts to flash together with a message on the display (for
versions/markets, where provided) when the system detects that the engine oil
has deteriorated.
If the warning light flashes, this does not mean that the vehicle is faulty, but simply
informs the driver that it is now necessary to change the engine oil as a result of
regular vehicle use. If the oil is not changed, warning light
will also come on
and engine operation is limited to 3000 rpm when a second threshold is reached.
If the oil is still not changed, when a third deterioration threshold is reached, the
engine is limited to 1500 rpm to avoid damage.Contact a Fiat Dealership as
soon as possible.
50) 51)
Remember that the
deterioration of the engine oil
is accelerated by:
– mainly town use of the
vehicle which makes the DPF
regeneration process more
frequent
– use of the vehicle for short
trips, preventing the engine
from reaching operating
temperature
– repeated interruption of the
regeneration process,
signalled by the DPF warning
light coming on.
redLOW ENGINE OIL LEVEL
When turning the ignition key to MAR, the warning light turns on but it should go
off after a few seconds.
This warning light appears on the panel when the engine oil level falls below the
minimum recommended value.
On certain versions a dedicated message is displayed.Restore the correct engine oil
level (see “Checking fluid
levels” in the "Maintenance
and care" section).
87

Warning lights on
panelWhat it means What to do
redDOORS OPEN
On certain versions, the warning light turns on when one or more doors or the
boot are not properly closed.
A buzzer will sound when doors/tailgate are open and the vehicle is moving.
WARNING
48)If thewarning light does not switch on when the key is turned to MAR or if it stays on when driving (together with the message on the
display), there may be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident
or, in a lower number of cases, they could deploy erroneously. Before continuing, contact a Fiat Dealership to have the system checked
immediately.
49)A failure of the
warning light is indicated by the blinkingwarning light. In this case, thewarning light may not indicate a possible
problem with the airbag restraint system. Before continuing, contact a Fiat Dealership to have the system checked immediately.
50)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.
51)If the
warning light flashes when driving, contact a Fiat Dealership.

Warning lights on
panelWhat it means What to do
amberEOBD/INJECTION SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR the
warning light switches on, but it should switch off as soon as the
engine is started.
The operation of the
warning light may be checked by the
traffic police using specific devices. Comply with the laws and
regulations of the country where you are driving.13)
If the warning light stays on or switches on when driving, it
means that the injection system is not working properly; in
particular, if the warning light comes on constantly, this indicates
a malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance,
poor driveability and high fuel consumption.
On some versions the display shows the dedicated message.
The warning light switches off if the malfunction disappears, but
the warning is still stored by the system.Under these conditions, the vehicle can
continue travelling at moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on fixed may cause damage.
Contact a Fiat Dealership as soon as possible.
NOTE (for petrol engine only)
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of the
engine until the warning light stops flashing.
Continue the journey at moderate speed, trying
to avoid driving conditions that may cause
further flashing and contact a Fiat Dealership as
soon as possible.

Warning lights on
panelWhat it means What to do
amberDPF (PARTICULATE FILTER) CLEANING UNDERWAY
(for versions/markets, where provided)
The warning light comes on when the ignition key is
turned to MAR, but should go off after a few seconds.
The warning light switches on constantly to inform the
driver that the DPF system needs to eliminate the trapped
pollutants (particulate) through the regeneration process.
A specific message will appear on the display when the
warning light comes on (for versions/markets, where
provided).The warning light does not come on during every DPF
regeneration, but only when driving conditions require
that the driver is notified. The warning light will go off if
the vehicle stays in motion until regeneration has been
completed. On average, the process lasts 15 minutes.
Optimum conditions for completing the process are
achieved by travelling at 60 km/h with engine revs
above 2000 rpm. If this warning light comes on, it
does not mean there is a vehicle defect, so there is no
need to take it to a garage.
