Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on when the ignition
key is turned to MAR, 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.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.
redLOW BATTERY CHARGE
The warning light switches on when the ignition
key is turned to MAR, but it should switch off as
soon as the engine has started (with the engine
idling a brief delay before switching off 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.
13)
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, 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.
47) 48)
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.

Warning lights on
panelWhat it means What to do
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).
redDOOR OPEN
On some versions the warning light turns on when one or more doors or the rear
swing doors/tailgate (for versions/market, where provided) are not properly closed.
A buzzer will sound when doors/tailgate are open and the vehicle is moving.Check that all doors or the
swing doors/tailgate (for
versions/markets, where
provided) are perfectly
closed.
WARNING
44)If thewarning light turns on while driving (on certain versions together with the message on the display) stop the car immediately and
contact a Fiat Dealership.
45)If the
warning light does not switch on when the key is turned to MAR or if it stays on while driving (together with the message on the
display), there may be an anomaly 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.
46)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.
47)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.
48)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 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.14)
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
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 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)
The warning light switches on when the ignition key is
turned to MAR, 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 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.
