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.
Automatically switching over from natural gas mode to petrol mode
The vehicle automatically switches from natural gas to petrol, for example, if
one of the following cases occurs.
› With an empty gas tank or not enough pressure in the tank.
› After refuelling with natural gas.
› At very low surrounding temperatures.
Gas smell
If you smell gas, proceed as follows.
› Stop the vehicle.
› Put out cigarettes.
› Switch off the ignition.
› Open the doors and the boot lid to ventilate the vehicle sufficiently.
› Remove any spark-producing or incendiary items from the vehicle and switch
off immediately.
› Do not continue to drive if the odour persists.
Seek help from a specialist garage to correct the gas system fault.
Regular gas system checks must be carried out at a specialist workshop on natural gas-powered vehicles.WARNINGWhen operating a CNG-powered vehicle, the national legal requirements
must be observed.WARNINGDo not underestimate the smell of gas in the car or when refuelling - risk of
fire, explosion and injury.
