WATER IN THE DIESEL FILTER (Diesel Versions)
When the key is turned to MAR, the symbol appears but it should switch off after a few seconds.
The symbol on the display switches on constantly when driving
to indicate the presence of water in the diesel filter.
On some versions, in alternative, the warning light
èswitches on and the display shows a dedicated message.

FIAT CODE SYSTEM FAILURE
With the key in the MAR position, on some versions the warning light, or the symbol on the display, turns on continuously,
along with a dedicated message on the display, to signal a possible Fiat CODE system failure.
If the warning light or symbol blinks on the display with engine running, it means that the vehicle is not protected by the
engine immobiliser device.
In this case, contact a Fiat Dealership as soon as possible.
REAR FOG LIGHTS
The warning light comes on when the fog lights are turned on.
GENERIC FAULT INDICATION
The warning light switches on in the following circumstances. In these cases contact a Fiat Dealership to have the fault fixed
as soon as possible.
Engine oil pressure sensor failure
The warning light switches on when the engine oil pressure sensor is incorrect.
Fuel cut-off system intervention/failure
This warning light switches on, on some versions along with a dedicated message on the display, in the case of fuel cut-off
system activation/fault.
Exterior lights failure
The warning light switches on when an external light fault is detected.

petrol operation with lighting of the
respective amber LED C;
❒ switch A pressed on the left side
(identified by the symbol G)
indicates LPG operation with
activation of the associated green
LED D.
Five LEDs B (one amber and four
green) on the top part of the switch
display the amount of LPG in the
cylinders.
If the LPG runs out, the system
automatically switches to petrol: the
amber LED C besides the switch
comes on and the green LED D
indicating LPG operation goes off.
60DVDF0S0189c
After refuelling with LPG, after a normal
start-up on petrol, the fuel system
automatically returns to LPG: the
amber LED C next to the switch goes
off and the green LED D for LPG
operation turns on.
If you specifically wish to run on petrol,
press the switch A on the right-hand
side.
The amber LED C next to the switch
will turn on to indicate that switching
has taken place (the LPG fuel system
has been entirely disabled).
The fuel supply can only be returned to
LPG by operating switch A again,
green LED D next to the switch will turn
on to indicate that switching has taken
place.
In addition, when starting at outside
temperatures below approximately –
10°C, the switching times from petrol
to LPG increase to allow the pressure
regulator/reduction unit to heat up.
IMPORTANT If switching takes place
during acceleration or setting off, there
may be a brief drop in power.MULTIMEDIA

IMPORTANT INFORMATION AND RECOMMENDATIONS
196
The engine can be stopped even if the DPF warning light is on:
however, repeated interruptions of the regeneration process could
cause premature deterioration of the engine oil.
For this reason, always wait until the warning light switches off
before stopping the engine as described above. Do not complete
the DPF regeneration process when the vehicle is stopped.
•Water in the fuel circuit may severely damage the injection
system and cause irregular engine operation. If the warning light
or the symbol
Eturns on (together with a message on the display
for some versions), 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.
• If the system signals a pressure decrease on a specific tyre, it is
recommended to check the pressure on all four tyres. The iTPMS
does not relieve the driver from the obligation to check the tyre
pressure every month; it is not to be considered a system to
replace maintenance or a safety system. Tyre pressure must be
checked with tyres cold. Should it become necessary for whatever
reason to check pressure with warm tyres, do not reduce
pressure even though it is higher than the prescribed value, but
repeat the check when tyres are cold.
• The iTPMS cannot indicate sudden tyre pressure drops
(for example when a tyre bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt steering.
The system only warns that the tyre pressure is low: it is not able
to inflate them. Insufficient tyre inflation increases fuel
consumption, reduces the tread duration and may affect the
capacity to drive safely.

PERSONAL SAFETY
(CONTINUED)
•If when turning the key to MAR the warning light ¬does not
turn on or if it stays on when travelling there could be a failure in
safety systems;
in this event airbags or pretensioners may not be deployed in
case of impact or, in a minor number of cases, they may be
deployed accidentally. Contact a Fiat Dealership immediately to
have the system checked.
•A fault to the
¬warning light is indicated, according to the
version, by the ¬symbol appearing on the display or by the èwarning light blinking. In this case, warning light ¬may not
indicate failures in the retaining systems. Before continuing,
contact a Fiat Dealership immediately to have the system
checked.
•The blinking
èwarning light on indicates possible ¬warning light faults. In this case, warning light ¬may not
indicate failures in the retaining systems. Contact a Fiat
Dealership immediately to have the system checked.
•If the warning light
vturns on when the car is travelling
(on certain versions together with the message on the display),
stop the car immediately and contact a Fiat Dealership.
•If the
vwarning light (or v, for versions/markets, where
provided) switches on, the degraded engine oil must be changed
as soon as possible, and never more than 500 km from the first
time that the warning light switches on. Failure to observe the
above may result in severe damage to the engine and invalidate
the warranty. The activation of this warning light is not related to
the amount of oil in the engine. Therefore, never top up with oil
when the warning light starts flashing.
•The driving speed must always be suitable for traffic and
weather conditions and the driver must always comply with the
Highway Code.

PERSONAL SAFETY
(CONTINUED)
42) INTERIORS
•Never use flammable products, such as petrol ether or rectified
petrol to clean the inside of the car. The electrostatic charges which
are generated by rubbing during the cleaning operation may cause
a fire.
•Do not keep aerosol cans in the vehicle: they might explode.
Aerosol cans must not be exposed to a temperature exceeding
50°C. When the vehicle is exposed to sunlight, the internal
temperature can greatly exceed this value.
43) TECHNICAL SPECIFICATIONS – FUEL SUPPLY
Modifications or repairs to the supply system that are not carried
out correctly or do not take the system technical specifications
into account can cause malfunctions leading to the risk of fire.
44) TECHNICAL SPECIFICATIONS – RIM PROTECTOR
TYRES
DO NOT fit wheel hub caps when using integral hub caps fixed
(with springs) to the steel rim and after sale tyres provided with
Rim Protector. Use of unsuitable tyres and wheel caps may cause
sudden decrease of tyre pressure.
45) LPG
•Note that in some countries (including Italy) there are legal
restrictions in force for parking/garaging motor vehicles fuelled by
gas that is denser than air; LPG comes under this category.
•Do not switch between the two operating modes (petrol/LPG)
whilst starting the engine.
•The LPG supply system is equipped with a “consumption”
function linked to the LED display of LPG level on the switch; this
function activates only after a consistent variation in fuel level has
been detected. •Running the battery with an excessively low liquid level will
damage the battery beyond repair and could even cause its
explosion.
•If the vehicle must remain unused for a long time at a very low
temperature, remove the battery and take it to a warm place, to
avoid freezing.
•When performing any operation on the battery or near it,
always protect your eyes with special goggles.
40) TYRES AND WHEELS
•Remember that the road holding qualities of your car also
depend on correct tyre pressures.
•If tyre pressure is too low, the tyre may overheat and be
severely damaged as a result.
•Do not switch tyres from the right hand side of the vehicle to the
left hand side, and vice versa.
•Never submit alloy rims to repainting treatments requiring the
use of temperatures exceeding 150°C.
The mechanical properties of the wheels could be impaired.
41) WINDSCREEN AND –REAR WINDOW WIPER
•Driving with worn windscreen/rear window wiper blades is a
serious hazard, because visibility is reduced in bad weather.
•If the window needs to be cleaned, make sure the device is
deactivated or the key is on STOP.
