The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
The natural gas system of your vehicle is suitable both for "slow fuelling" (fuel-
ling from small compressors) and for "quick fuelling" (fuelling from natural gas
stations with large compressors).
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not
indicate exactly the same level as was the case immediately after refuelling
when the engine is restarted. This is not due to any system leakages but a
drop in pressure in the natural gas fuel tank due to technical reasons after a
cooling phase directly after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is about 11 litres, of which about 1.5
litres are in reserve.
The capacity of the gasoline fuel tank is about 10 litres, of which about 5 litres
are in reserve.
WARNING
When refuelling, never get into the vehicle. If you have to get into your
■
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. This will avoid electrostatic discharges, which may
generate sparks. Sparks can cause a fire during refuelling.
Natural gas is highly explosive and highly flammable.
■
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.

Natural gas quality and consumption
Depending on the natural gas supplier, the natural gas quality (heating value)
may vary. The engine control unit adjusts automatically to the natural gas
quality.
