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.
