FUEL CUT-OFF SWITCH
The safety switch will be tripped in case of vehicle
collision and will cut off natural gas supply, thus causing
the engine to be switched off.
For further information, refer to the Owner
Handbook, chapter “Dashboard and controls”,
paragraph “Fuel cut-off switch”.ENGINE STARTING
To start the engine correctly, refer to the warnings
and recommendations provided in the Owner
Handbook, chapter “Engine starting”.
Emergency starting
If the Fiat CODE system is not able to deactivate the
engine lock, warning light ¢will remain ON and the
engine won’t start. Refer to the Owner Handbook,
chapter “Emergency starting”.
WARNINGThe Natural Power Fiat Multipla engine is always started by using petrol, even
when the switch is set to the “Natural gas” position; in this case, the green LED on
the switch will indicate that the engine is fuelled by petrol and will remain such
until automatic switching to natural gas has taken place: now, the green LED on
the switch will go out.
Therefore, it is required that reserve fuel is always available in the petrol tank.

FUEL FEED (Natural gas)
Electronic injection specific to the natural gas.
Type: Sequential, timed Multipoint injection.
Injection pressure: approximately 9 bar.
Stoichiometric metering of the air/natural gas mixture.
The natural gas injection system is controlled by a
special control unit by making use of the sensors
previously fitted to the vehicle, including the oxygen
sensor for fuel metering control.
IGNITION
Electronics with static advance integrated with
injection.ENGINE COOLING
Engine cooling system with branching-off to bring hot
fluid in contact with the pressure reducer (which is
subject, during its operation, to heavy cooling).
PERFORMANCE
Maximum speeds in the 5
thgear (kph):
petrol fuelling: 168
natural gas fuelling: 157
Any modification or repair made to the fuel feed system in a wrong way and
without considering the technical features of the system may cause operating
anomalies with a risk of fire.WARNING

FUELLING AND FILLING
Person transport version
Petrol .................................................................. litres 38
❐ including a reserve of .................................. litres 5
Natural gas (*)
❐ bottle ................................................................ litres 164
❐ Natural gas (*) ............................ m338.9 (kg 26.49)
(*) Natural gas in standard conditions: 15°C; 1.013 bar; density: 0.680
kg/m3.
IMPORTANT! Please be reminded that when natural
gas is used to fuel the vehicle, the fuel distance may
vary to some extent since it depends on the vehicle
maintenance and driving conditions as well as the
temperature of the gas in the bottle.
In fact, natural gas heats up when it is filled and cools
when the vehicle is running, thus undergoing pressure
variations that reduce the amount of gas that can be
used.ENGINE OIL
IMPORTANT! As regards the engines powered by
alternative fuels (natural gas), a multigrade engine oil
shall be used, which shall feature very high fluidity,
grade: SAE 5W30, specifications ACEA A1-A5 - API SL
and FIAT 9.55535-M1.
Therefore, it is recommended that you use the
SELENIA PERFORMER MULTIPOWER oil.
