Several warning and control lamps should light up for a few seconds when
the ignition is switched on, signalling that the function is being verified.
They will switch off after a few seconds.
In natural gas engines
The warning lamp lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp lights up when the vehicle is running in natural gas op-

The warning lamp switches off when the natural gas is exhausted. The en-
gine changes to operate with petrol.
Problem: If the vehicle is left parked for a long period immediately after re-
fuelling, 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 pressure in the gas tank for techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
110.
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially 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 assistance sys-
tems, including braking assistance, will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
CAUTION
● Always pay attention to any lit control lamps and to the corresponding
descriptions and instructions to avoid damage to the vehicle.
● Never run the fuel tank completely dry. An irregular fuel supply may lead
to ignition faults and unburnt fuel could enter the exhaust system. This
could damage the catalytic converter.
Note
The arrow next to the fuel pump symbol on the instrument panel
indicates the side of the vehicle on which the tank flap is located.
