FIAT PUNTO NATURAL POWER
FUEL CUT-OFF SYSTEM
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.

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.
