The four vertical bars near the letters
CNG in the instrument panel display
Fig. 11indicate the level of methane in
the cylinders.
When the residual amount of methane
goes below 1/5 of the capacity of the cylin-
ders, the CNG icon and the lowest level
Fig. 12flash to indicate the reserve and
notify the need to refuel.
If the methane has run out, the switch to
petrol operation takes place automatical-
ly: the Ksymbol near the CNG icon
Fig. 11in the instrument panel display
comes on.
If you specifically wish to run on petrol,
press the dedicated button Fig. 10locat-
ed 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 shall be re-
quested manually by the customer.
Manual switching of the operat-
ing mode from petrol to meth -
ane and vice versa is only acti-
vated if the engine speed is below
2000 rpm.
At the time of the switching
request there will be a
metallic noise coming from the valves
to pressurise the circuit (more obvi-
ous with the ignition key in the MAR
position). As a result of the switching
logics described above, ithe delay be-
tween the ticking of the valve and the
display switching off on the instru-
ment panel is entirely normal.
IMPORTANT
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.
