2007 FIAT MULTIPLA Natural Power Manual

9
PIPES
The natural gas pipes are made of galvanized iron and coated with plastic
material.
PRESSURE REDUCER/REGULATOR
The pressure reducer is installed in the engine compartment.
Its function is to reduce the natural gas pressure from the value found in
the bottle to the natural gas injector feed value (approximately 9 bar) and
keep the same constant under any operating condition.
NATURAL GAS INJECTORS
Four special natural gas injectors directly fitted into the cylinder head,
one for each intake manifold; they are fed at a steady pressure
(approximately 9 bar) and operated by the special electronic control unit.
ELECTRONIC CONTROL UNIT FOR NATURAL GAS
SYSTEM
Special electronic control unit for ignition advance and natural gas feed
control.
In the event that the natural gas runs out, the control unit will
automatically manage the shift to the petrol feed mode.
The control unit is located under the dashboard, on the passenger’s side.

NATURAL GAS/PETROL SWITCH
As a rule, the engine is fuelled by natural gas (both the LED on button (A)
and warning light K(C) on the instrument board are OFF); in the event
that the natural gas runs out, switching to petrol fuelling will take place
automatically (warning light Kon the instrument board will be ON).
After filling up, the engine will be automatically fuelled by natural gas
again.
If you specially want the engine to be fuelled by petrol (for instance, when
greater power is required), act on switch (A).
Both warning light Kon the instrument board and green LED (B) on
button (A) light up to indicate that manual switching has taken place (the
natural gas feed system is fully OFF).
Manual selection of the operating mode is actuated only if the engine
speed is lower than 2,000 rpm.
Natural gas operation is resumed only by acting on switch (A) again (LED
OFF): the respective warning light Kon the instrument board will go out.
Do not switch over between the two operating modes during the engine
starting phase.

GAUGE INDICATING THE AMOUNT OF NATURAL GAS IN
THE BOTTLE
The gauge is always illuminated, both when the engine is fuelled by
natural gas and petrol.
The bottles are full when all of the six green nicks of the meter are fully
covered. Nick (A) (amber yellow) lights up to indicate that the engine is
low on fuel and must therefore be filled up.
When the last green nick goes out (natural gas run out), automatic
switching to petrol fuelling will take place, which will be signalled by the
lighting of warning light Kon the instrument board.
Natural gas operation will be automatically resumed upon the next fill-up.
WARNING! Petrol shall always be available in the tank.

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.

AT THE FILLING STATION
NATURAL GAS FILLING PIPE UNION
The natural gas filling pipe union (B) is located next to the petrol pipe
union and can be accessed by opening the fuel lid.
It is equipped with a dual “non-return” valve: one fitted into the pipe
union body itself; one located next to the bottle, at the start of the filling
pipe.
To gain access to pipe union (B), unscrew cap (A).
The contour of pipe union (B) is of the “multi-purpose” type.
During filling up, natural gas pipe union cap (A) can be positioned directly
on the lid, as illustrated.
In certain European States, the adaptors are considered ILLEGAL (e.g.
Germany).
In the case of service stations equipped with m
3gas guns (with dissolved
air pressure) so as to verify the residual pressure in the gas bottle, the
non-return valves must be unblocked by supplying a small quantity of
Methane.
The other plates (delivered with the vehicle documents) indicate the
expected date for the first testing/inspection of the gas bottles.
The employees assigned to the Methane supply are not authorised to fill
the gas bottles with the test date expired.

IF A TYRE IS PUNCTURED
General remarks
Only for Italian market, the FIX & GO quick tyre repair kit is provided as
a standard item in place of the traditional tool kit and space-saver spare
wheel.
The standard space-saver spare wheel can be supplied on request.
VAN versions are fitted as a standard spare wheel with steel rim of the
same type and size as the standard wheels mounted on the car.
As regards the use of the FIX & GO and the space-saver spare wheel,
follow the instructions of the Owner Handbook, chapter “In an
emergency”, paragraph “If a tyre is punctured”.
Space-saver spare wheel
The space-saver spare wheel is positioned in a horizontal position on the
right side of the luggage compartment and is protected by a special
coating (A).
The space-saver spare wheel can be removed as follows:
❐ lift the covering secured to the space-saver spare wheel base by means
of an elastic strap, then remove the same;
❐ unscrew fastening device (B) until it comes out of its respective pin;
❐ take off the complete wheel.
Removable pin for space-saver spare wheel fastening
If you wish to obtain an even, smooth plane in the luggage compartment,
you may remove the space-saver spare wheel fastening pin (A) (this
operation must be carried out at the Fiat Dealership) and then plug the
hole by cap (B).
IMPORTANT! The space-saver spare wheel must, when available on the
vehicle, always be secured to its respective pin for safety reasons.

IDENTIFICATION DATA
IMPORTANT! If a vehicle has been registered in a country other than
Italy, the certification/identification data and the natural gas bottle
check/inspection procedures shall conform to the national law
regulations of that particular country. In any case, it must be specified
that, the life cycle of the gas bottles is 20 years from the date of
production as in ECE Regulation n° 110.
Bottle marking
Each natural gas bottle is identified at the manufacturing plant by means
of a hallmark made on the nose of the bottle itself.
The hallmark bears the following information:
❐ Type of gas for which it is indicated (Methane);
❐ 20-year expiry date of the gas bottle (month/year);
❐ Name of the manufacturer of the gas bottle;
❐ The gas bottle registration number of the gas bottle;
❐ Nominal capacity of the gas bottle in litres;
❐ Weight of the gas bottle in kg (specific for every gas bottle);
❐ Working pressure (200 bar at 15°C);
❐ Testing pressure of the gas bottle (300 bar);
❐ Identifying stamp of the certifying Nation;
❐ ECE certification number;
❐ Production date of the of the gas bottle (month/year).
The other plates (delivered with the vehicle documents) indicate the
expected date for the first testing/inspection of the gas bottles.
BOTTLE INSPECTION
The gas bottles must be checked, according to the ECE Regulation
procedure n° 110, every 4 years as from, the vehicle registration date, or
according to specific provisions made by single States.
