The vehicle is running with natural gas.
The warning lamp t
urns off when the natural gas runs
out. The engine changes to operate with petrol.
It lights up, and in addition, the
low
er diode lights up in red
The fuel reserve level has been reached.
When the fuel lev
el is very low, the lower diode flash-
es in red.
The display only works when the ignition is
s
wit
ched on.
Things t
o note
If the vehicle is left parked for a long time im-
mediately after refuelling, the natural gas lev-
el indicator may not accurately indicate the
same level shown after refuelling when the
vehicle is started up again. This is not due to a
leak in the system, but to a drop in pressure in
the gas tank for technical reasons after a
cooling phase just after refuelling.

Normal zone. At high outside tempera-
tures and when making the engine work
hard, the diodes may continue lighting up
and reach the upper zone. This is no
cause for concern, provided the control

ing hard, especially at high outside tem-
peratures, the diodes may light up in the
