PIPING
The methane piping from the filler to the
pressure regulator/reduction unit is made
from galvanized steel and covered in plas-
tic (high pressure) and is located outside
the passenger compartment; the piping
from the pressure regulator/reduction
unit to the methane injectors is in stain-
less steel.
PRESSURE
REGULATOR/
REDUCTION UNIT
The pressure reduction unit Fig. 8is in-
stalled in the engine compartment.
It has the task of reducing the pressure
of the methane from the value in the can-
ister to the supply value for the methane
injectors (about 6 bar) and keeping it con-
stant in all operating conditions.
METHANE INJECTORS
There are 4 dedicated injectors for the
methane gas A-Fig. 9, fitted on the intake
manifold near the cylinder head, one for
each intake duct; they are supplied at a
constant pressure (about 6 bar) and op-
erated by the electronic control unit.
OIL SEPARATOR FILTER
The oil separator filter Fig. 10is installed
in the engine compartment.
It has the task of separating the excess oil
in the methane.
PETROL/
METHANE SWITCH
This engine normally runs on methane ex-
cept during starting when it runs on
petrol. Switching to methane takes place
automatically and is shown on the instru-
ment panel display by the Ksignal in the
display going out fig. 12.

Do not switch between the
two operating modes whilst
starting the engine
WARNING
In addition, in the case of starting at out-
side temperatures of below around -10°C,
the switching times from Petrol to
Methane increase to allow the pressure
regulator/reduction unit to become warm
enough.
IMPORTANT If the switching takes place
during acceleration or pick-up, there may
be a brief flat spot (fall in power).With the reconfigurable multifunction dis-
play, any system failure is signalled by the
dedicated message and, at the same time,
by the symbol coming on and the four
methane levels going out. In this case, go
to a Fiat Dealership as quickly as possi-
ble.
STARTING
THE ENGINE
To carry out the starting manoeuvre, see
the warnings and advice in the Owner
Handbook under the chapter “Starting the
engine”.
PROTECTIVE FUSES
The table below contains a list of the pro-
tective fuses with reference to the
petrol/methane version. For all the other
fuses, consult the Owner Handbook that
this supplement comes with.
If the methane has run out, the control
unit automatically manages the switch to
running on petrol.

10 SYSTEM FAILURE SIGNALLING
With the multifunction display, any system
failure is signalled through a dedicated
messages and, at the same time, by the
CNG logo and the four methane levels
flashing (with solid bars). In this case, go
to a Fiat Dealership as quickly as possi-
ble.

CAPACITIES
Petrol
Petrol . . . . . . . . . . . . . . . . . litres 45
- including a reserve of . . . . litres 5-7
Methane
– Methane (*). . . . . . . . . kg (approx) 13
(*) The amount of methane depends on
the outside temperature, the supply pres-
sure, the quality of the gas and the type
of refuelling system. The total volume of
the canisters is about 84 litres.
IMPORTANT It should be remembered
that when using a fuel such as methane the
range is very variable because as well as
the driving conditions and car maintenance
it also depends on the temperature of the
gas in the canister.
The methane actually heats up during the
refuelling and cools down whilst driving,
undergoing variations in pressure that re-
duce the quantity that can be used.
It should also be pointed out that whilst
the vehicle is being run in (up to around
3000 km) the fuel consumption may be
higher than the figures given.
ENGINE OIL
The engine oil used is SELENIA K P.E.
(Contractual Technical Reference
N° F603.C07): SAE 5W-40 ACEA C3
grade synthetic base lubricant, FIAT
9.55535-S2 certification.

low refer to combined fuel consumption.
