The four vertical bars near the letters
CNG in the instrument panel display Figs.
12a-12bindicate the level of methane in
the canisters.
When the residual amount of methane
goes below 1/5 of the capacity of the can-
isters, the CNG logo and the lowest lev-
el Fig. 13flash to indicate the reserve and
notify the need to refuel.
If the methane has run out, switching to
petrol takes place automatically: the Kin-
dicator near the CNG symbol Figs. 12a-
12blights up in the instrument panel dis-
play.
If you particularly want the car to run on
petrol, press button A - Fig. 11located
between the controls in the dashboard.
The LED in the button coming on means
that the request to switch has taken place
correctly.

If the last fuel system in use
was petrol, when starting the
switch to methane should be
requested manually by the
customer.
The actual change to the chosen fuel sys-
tem takes place depending on the vehicle
usage conditions to guarantee switching in
absolute safety and will be confirmed by
the Kwarning light in the instrument pan-
el display coming on/going off.
The manual selection of the op-
erating mode from petrol to
methane and viceversa is only ac-
tivated if the engine speed is be-
low 2000 rpm.
At the time of the switching
request there will be a metal-
lic noise coming from the valves to
pressurize the circuit (more obvious
with the ignition in the MAR position).
As a result of the switching logics de-
scribed above, it is entirely normal for
there to be a delay between the tick-
ing of the valve and the switching off
at the instrument panel.

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
Rsymbol 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.

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.

FUEL CUT OFF SWITCH
The safety switch is triggered in the case
of an impact, cutting off the methane sup-
ply and causing the engine to cut out.
For further information, see the “Fuel cut
off switch” paragraph in the “Controls”
chapter in the Owner Handbook.
AT THE
FILLING STATION
METHANE GAS FILLER
The methane filler is located near the
petrol one Fig. 14.
It is comes complete with a “single-acting”
valve: fitted in the actual filler casing.
To access the filler, undo the cap A - Fig.
15turning it anti-clockwise.
The profile of the filler
Bfor refilling is the
universal type compatible with Italia and
NGV1 standards.
In some European countries adaptors are
considered ILLEGAL (e.g. in Germany).
In the case of service stations with m
3(dif-
ferent pressure) nozzles, to measure the
residual pressure in the canister, the sin-
gle-acting valves must be undone supply-
ing a small amount of methane.
fig. 14F0M0463m
The other plates (handed over with the
car documentation) contain the date for
the first canister inspection.
Those responsible for the methane supply
are not authorized to refill the canisters
when the inspection date has expired.

IDENTIFICATION DATA
IMPORTANT If the car has been
registered in a country other than
Italy, the certification data, identifi-
cation and inspection procedures for
the methane canisters should con-
form to the legislation in that coun-
try. In any case, it should be re-
membered that the life of the can-
isters is 20 years from the produc-
tion date as set out in ECE Regula-
tion no. 110.
Marking the canisters
Each methane canister is identified in the
factory with a stamp on the nose of the
actual canister.
fig. 16F0M0465m
The stamp includes:
CNG ONLY(type of gas designed for:
compressed natural gas only);
DO NOT USE AFTER
-
(canister expiry date: month-year);
FABER(name of canister manufacturer);
/ / (canister regis-
tration number);
L(nominal canister capacity in litres);
KG(weight of canister kg: specific
for each canister);
20.0MPa15°C(operating pressure at
15°C);
30.0MPa(canister test pressure);
E
110R-(ECE homologa-
tion number);ECE R 110(manufacturing regulations);
CNG-1(type of canister);
/ (canister manufacture test
date: month/year);
USE ONLY FABER-APPROVED
PRD(PRD safety device warning);
(–N)(ENI stamp).
The other plates (handed over with the
car documentation) contain the date for
the first inspection of the canisters.
SYSTEM INSPECTION
The canisters should be inspected, in ac-
cordance with ECE Regulation Procedure
no. 110, every 4 years from the vehicle
registration date or in accordance with
specific regulations in individual countries.

methane gas mixture.
The methane injection system is con-
trolled by the dedicated control unit us-
ing the sensors already on the car, in-
cluding the Lambda sensor for controlling
the fuel metering.
IGNITION
Static advance, electronic, integrated with
the injection.ENGINE COOLING SYSTEM
Engine cooling system with pressure re-
duction unit heating circuit subject to
strong cooling during operation.
PERFORMANCE
Top speed in km/h.
Running on petrol: 162
Running on methane: 156
Modifications or repairs to
the fuel feed system that are
not carried out properly or do not
take the system’s technical specifica-
tions into account can cause mal-
functions leading to the risk of fire.
