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.
If the vehicle is parked directly after a refuelling operation, on restart the
pointer of the gas gauge may not show exactly the same level as immediately
after the filling process. This is not a leak in the system, but a reduction in
pressure due to the cooling of the gas in the gas tank after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
WARNING
Natural gas is highly explosive and highly flammable.
■
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. Otherwise, electrostatic discharging may occur -
There is a risk of fire!
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.
