VERY IMPORTANT
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.

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.
4) 5) 6) 7)
STEERING LOCK
Activation
When the key is at STOP, remove
the key and turn the steering wheel
until it locks.
Deactivation
Move the steering wheel slightly as
you turn the ignition key to MAR.
WARNING
4) If the ignition device has been
tampered with (e.g. an attempted
theft), have it checked over by a
Fiat Dealership before driving
again.
5) Always remove the key when you
leave your vehicle to prevent
someone from accidentally
operating the controls. Remember
to engage the handbrake.
Engage first gear if the vehicle is
parked uphill or reverse gear if the
vehicle is parked downhill. Never
leave children unattended in the
vehicle.6) Never extract the key while the
vehicle is moving. The steering
wheel will automatically lock
as soon as it is turned. This also
applies to cases in which the
vehicle is towed.
7) It is absolutely forbidden to carry
out any after-market operation
involving steering system or
steering column modifications
(e.g.: installation of anti-theft
device) that could badly affect
performance and safety, cause
the lapse of warranty and also
result in non-compliance of the
vehicle with type approval
requirements.

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)
IMPORTANT
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)
IMPORTANT
10) If the needle for the engine
coolant temperature reaches the
red area, stop the engine
immediately and contact a Fiat
Dealership.

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, the
warning 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.

Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE
TOO HIGH
When the key is turned to MAR, the
warning light switches on but it should
switch off after a few seconds. The warning
light turns on when the engine is
overheated.
The display shows the dedicated message.When driving normally: stop the vehicle, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. If it is, 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. 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.
redLOW BATTERY CHARGE
The warning light comes on when the
ignition key is turned to MAR, but it should
go out as soon as the engine has started
(with the engine running at idle speed a
brief delay before going out is acceptable).If the warning light stays on, contact a Fiat Dealership
immediately.
95

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)
ENGINE OIL DETERIORATED
(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, when
a second deterioration threshold is reached, the
warning light also
switches on in the instrument panel and the engine operation is limited to
3000 rpm.
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.
96
KNOWING THE INSTRUMENT PANEL
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 "Servicing and
maintenance" section).

Warning lights on
panelWhat it means What to do
redINCOMPLETE DOOR LOCKING
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) Failure of the
warning light is indicated by thewarning light coming on. In this case, thewarning light may
not indicate a fault in the restraint systems. Before continuing, contact a Fiat Dealership to have the system checked
immediately.
50) Deteriorated engine oil must be replaced as soon as possible after the
warning light comes on, and never more
than 500 km after it first switches on. Failure to observe the above indications 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.
97
IMPORTANT
12) If thewarning light switches on when driving, stop the engine immediately and contact a Fiat Dealership.

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD 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
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 it is still stored by the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the vehicle with
the warning light on constantly 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.

amberDPF (PARTICULATE FILTER) CLEANING
UNDERWAY
(for versions/markets, where provided)
When the key is turned to MAR, the warning light
switches on but it should switch 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 dedicated message will appear on the display
when the warning light switches 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 switch off if the vehicle remains
in motion until regeneration has been
completed. On average, the process lasts 15
minutes.
The best conditions to complete the
regeneration process are reached by driving the
vehicle constantly at 60 km/h with engine speed
above 2000 rpm. When this warning light
comes on, it does not indicate a vehicle failure
and it should not therefore be taken to a
workshop.
