the LPG flow if the fuel locking inertia
switch is activated.
the pressure regulatorallows the
LPG to pass from a liquid state to a
gaseous state through an expansion
chamber and maintains the pressure
required for the operation of the system
at a preset value.
LPG FILTER
The filter, located on the pressure
regulator outlet pipe fig. 74 filters the
gaseous LPG during the LPG injector
supply stage.
LPG INJECTORS
There are four injectors specifically for
LPG on a dedicated bracket on the
cylinder head and connected, via
specific pipes, to the individual intake
ducts fig. 75.
They are supplied with LPG in agaseous state at a constant pressure
and are controlled by a specific
electronic control unit.
A gas pressure and temperature sensor
that sends an appropriate electrical
signal in order to determine the LPG
injection time is fitted on the injectors.
ELECTRONIC CONTROL
UNIT
The car has a special electronic control
unit fig. 76, in the engine compartment,
controlling the LPG supply, using the
sensors located on the car.
The control unit for the injectors has the
same strategy as the petrol control unit
(timed sequential Multipoint).
LPG/PETROL SWITCH
This engine normally runs on LPG
except during starting when it runs on
petrol. Switching to LPG is automatic,
the warning light
1 fig. 77 on the
instrument panel, switches off.
If you specifically want to use petrol,
press the button on the dashboard
fig. 78. If the LED located above the
button turns on, it indicates that

Symbol What it means
ENGINE OIL DETERIORATED
(where provided)
Diesel versions: the symbol turns on and is displayed for 3 minute cycles and intervals of
5 seconds until the oil is changed.
The symbol is displayed until the problem is solved.
Petrol versions: the symbol switches on and then is not displayed when the display cycle is
completed.
IMPORTANT After the first indication, each time the engine is started the symbol will continue
to switch on as described above until the oil is changed.
If the symbol flashes, this does not mean that there is a fault on the vehicle, rather it simply
reports that it is now necessary to change the oil as a result of regular use of the vehicle.
The deterioration of engine oil is accelerated by using the vehicle for short drives, preventing
the engine from reaching operating temperature.
Contact a Fiat Dealership as soon as possible.
23) 24)
RAIN SENSOR FAILURE
The symbol switches on in the case of failure of the rain sensor. Contact a Fiat Dealership as
soon as possible.
FUEL CUT-OFF SYSTEM OPERATION
The symbol switches on in the event of fuel cut-off system intervention.
For reactivating the fuel cut-off system, refer to the description in the "Fuel cut-off system"
section in the "In an emergency" chapter. If it is still not possible to restore the fuel supply,
contact a Fiat Dealership.
FUEL CUT-OFF SYSTEM FAILURE
The symbol switches on in the event of fuel cut-off system failure. Contact a Fiat Dealership as
soon as possible.
WATER IN DIESEL FILTER (Diesel versions)
The symbol switches on constantly when driving (along with a message in the display), to
indicate the presence of water in the diesel filter.
25)
START&STOP SYSTEM FAILURE
(for versions/markets, where provided)
The symbol switches on to report a failure of the Start&Stop system. The display will show a
dedicated message. Contact a Fiat Dealership as soon as possible.

System activation
Activation of the system is indicated by
the
warning light switching on and,
where provided, by a message on the
display.
System deactivation
Deactivation of the system is indicated
by the
warning light switching on
and, where provided, by a message on
the display.
MISSED ENGINE
STOPPING CONDITIONS
42)
When the system is active, for a higher
comfort and safety, and to reduce
emissions, the engine does not stop in
some conditions, such as:
engine still cold;
especially cold outside temperature;
battery not sufficiently charged;
particulate filter (DPF) regeneration in
progress (Diesel engines only);
driver's door not shut;
driver's seat belt not fastened;
reverse gear engaged (e.g. for
parking manoeuvres);
only for versions equipped with an
automatic climate control, if an
adequate level of thermal comfort has
not been reached or with MAX-DEF
function active;
during the first period of use, to
initialise the system.
ENGINE RESTARTING
CONDITIONS
Due to comfort, emission control and
safety reasons, the engine can restart
automatically without any action by the
driver, when the car and the passenger
compartment climate control system
are in certain conditions, such as:
With gear engaged, automatic engine
restarting is possible only by fully
pressing the clutch pedal.
SAFETY FUNCTIONS
When the engine is stopped through
the Stop/Start system, if the driver
releases their seat belt or opens the
driver's or passenger's door, the engine
can be restarted only by using the
ignition device.
This condition is indicated to the driverboth through a buzzer and a message
on the display.
"ENERGY SAVING"
FUNCTION
If, following the automatic engine
restarting, the driver does not carry out
any action for more than 3 minutes, the
Stop/Start system stops the engine
definitely, to prevent fuel consumption.
In these cases, the engine can only be
restarted using the ignition device.
NOTE In any case, it is possible to keep
the engine running by deactivating the
system.
IRREGULAR OPERATION
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, see the "Warning
lights and messages" paragraph,
"Knowing the instrument panel"
chapter.
VEHICLE INACTIVITY
113)
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of
the battery power supply.
