INDEXA specific message is displayed on certain versions.
Under these conditions, the vehicle can continue trav-
elling at moderate speed without demanding exces-
sive effort from the engine. Prolonged use of the ve-
hicle with the warning light on may cause damage. Go
to a Fiat Dealership as soon as possible.
The warning light goes out after the fault disappears,
but the notification is stored in the system.
❒flashing: this indicates possible damage to the catalytic
converter (see “EOBD system” in the “Dashboard and
controls” section).
If the light flashes, come off the accelerator pedal to
reduce engine revs until the warning light stops flash-
ing; continue the journey at moderate speed, trying
to avoid driving conditions that may cause further flash-
ing, and get to a Fiat Dealership as soon as possible. INJECTION SYSTEM FAILURE
(Multijet versions – amber)
EOBD ENGINE MANAGEMENT
SYSTEM FAILURE
(petrol versions – amber)
Injection system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the
engine starts. If the warning light stays on or comes on
when travelling, it means there is a fault in the injection
system which could cause loss of performance, poor han-
dling and high fuel consumption levels.
A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue travel-
ling at moderate speed without demanding excessive ef-
fort from the engine. In any case, you should go to a Fiat
Dealership as soon as possible.
EOBD engine management system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the
engine starts.
This indicates that the warning light is working correctly.
If the warning light either stays on or comes on during
your journey:
❒on permanently: this means there is a fault in the sup-
ply/ignition system which could cause high exhaust
emissions, loss of performance, poor handling and high
fuel consumption levels.
U
Go to a Fiat Dealership as soon as possi-
ble if warning light
Udoes not light up
when the key is turned to MAR or if, while
travelling, the warning light comes on either per-
manently or flashing (along with a message on the
display on certain versions). The operation of the
Uwarning light may be checked by traffic police
using appropriate equipment. Respect the regula-
tions in force in the country where you are driving.

FUEL RESERVE
(amber)
When the ignition key is turned to MAR, the
warning light turns on but should go off after a
few seconds.
The warning light turns on when 8-10 litres of fuel are
left in the tank.
IMPORTANT The warning light will blink to indicate a sys-
tem failure. If this happens, go to a Fiat Dealership to have
the system checked. DPF (PARTICULATE FILTER)
CLEANING IN PROGRESS
(only Multijet versions with DPF
– amber)
When the ignition key is turned to MAR, the warning light
turns on but should go off after a few seconds. The warn-
ing light stays on constantly to notify the driver that the
DPF system needs to eliminate captured pollutants (par-
ticulate) by the regeneration process.
The warning light does not come on during every DPF
regeneration, but only when driving conditions require
notification to the driver.
The warning light will go off if the vehicle stays in motion
until regeneration has been completed. The process nor-
mally takes about 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 the vehi-
cle is defective, so there is no need to take it to a garage.
A specific message will appear on the display when the
warning light comes on (for versions/markets where pro-
vided).
h
ç
Always drive at a speed appropriate to the
traffic conditions, the weather and speed
limits. The engine may be turned off while the DPF
light is on; however, repeated interruption of the
regeneration process may result in premature degra-
dation of the engine oil. For this reason, it is always
advisable to wait for the light to go off before turn-
ing off the engine, following the instructions ap-
pearing above. It is recommended to complete DPF
regeneration with the vehicle stationary.

❒if in this case a pressure of at least 1.8 bar is not reached
within five minutes of switching on the compressor,
do not continue driving because the tyre is too dam-
aged and the hold cannot be guaranteed. Contact
a Fiat Dealership
❒if you do reach the tyre pressure specified in the “Cold
tyre pressures” paragraph of the “Technical specifica-
tions” section, continue your journey immediately; ❒make sure that switch E-fig. 145 of the compressor is
in position 0 (off), start the engine, insert plug D-fig.
144 into the socket and activate the compressor by
turning switch E-fig. 145 to position I (on). Inflate the
tyre to the pressure specified in the “Cold tyre pres-
sures” paragraph in the “Technical specifications” sec-
tion. For a more accurate reading, check pressure
gauge F-fig. 145 with the compressor off;
❒if a pressure value of a least 1.5 bar is not reached with-
in five minutes, disconnect the compressor from the
valve and socket, move the vehicle forwards by about
10 metres to distribute the sealant fluid within the tyre
and repeat the inflation procedure;

❒If you get a pressure reading of at least 1.8 bar, restore
the proper pressure (with engine running and hand-
brake on) and continue your journey.
❒drive with the utmost care to the nearest Fiat Dealer-
ship. ❒after driving for about 10 minutes, stop and check the
tyre pressure again; remember to put the handbrake
on;
Apply the adhesive label where it can be
easily seen by the driver as a reminder that
the tyre has been treated with the quick repair
kit. Drive carefully, particularly on bends. Do not
exceed 80 km/h. Do not accelerate or brake sud-
denly.
WARNING
If the pressure has fallen below 1.8 bar,
do not drive any further: the automatic
Fix & Go quick tyre repair kit cannot guarantee
proper hold because the tyre is too damaged.
Contact a Fiat Dealership.
WARNING
Remember to inform the workshop that
the tyre has been treated with a quick re-
pair kit. Give the instruction booklet to the per-
sonnel charged with handling the treated tyre.
