Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.
In natural gas engines
While in gear, the fuel level indicator gauge
appears in the fuel area with which it is flow-
ing at that time. When the ignition is connec-
ted, the gauge first changes for a few sec-
onds to the petrol area to show the actual
level of this petrol. Then, the gauge moves to
the natural gas level. After turning on the en-
gine, the gauge changes to the area corre-
sponding to the operating mode at that time.
Problem: if the vehicle is left parked for a
long time just after refuelling, the gas level
indicator does 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 pres-
sure in the gas tank for technical reasons af-
ter a cooling phase immediately after refuel-
ling.
WARNING
Driving with insufficient fuel reserve could re-
sult
in the vehicle breaking down in traffic
and a serious accident.
●
If the fuel level is too low then the fuel sup-
ply to the engine can become irregular espe-
cially on slopes.
●
If the engine “is choked” or stalls due to
lack of or irregularity of the fuel supply, the
power steering as well as all of the driver as-
sistance systems including braking assis-
tance will stop working.
●
Always refuel when there is only one quar-
ter of the fuel tank left to avoid running out of
fuel.
