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.

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.

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

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.

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.

operation. If the
warning light switches on (on some versions together with the dedicated message on the
display), contact a Fiat Dealership as soon as possible to have the system bled. If the above indication occurs
immediately after refuelling, water may have entered the tank: turn the engine off immediately and contact a Fiat
Dealership.
15) During regeneration, the fan may be activated.
WARNING
52) Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine may be
stopped if the DPF light is on; however, repeated interruption of the regeneration process may result in premature
deterioration of the engine oil. For this reason, always wait until the warning light switches off before stopping the
engine as described above. It is not advisable to complete DPF regeneration with the vehicle stationary.
