Checklist
In some countries, special safety standards and emissions-related legislation apply that may
differ from the construction of the vehicle. Volkswagen recommends that you visit your
Volkswagen dealership before travelling abroad to find out about any legal requirements and
the following issues at your destination:
Driving through water on roads

than the engine requires. However, this does not provide any advantage in terms of fuel
consumption or engine output.
Volkswagen recommends using fuel with a low sulphur content or sulphur-free fuel for petrol
engines in order to achieve reduced fuel consumption.
Petrol additives
The quality of petrol influences the running properties, performance and service life of the engine.
This is why the vehicle should be refuelled with good quality petrol that has only non-metallic
additives pre-added by the petroleum industry. These petrol additives help to prevent corrosion,
keep the fuel system clean, and prevent the build-up of deposits in the engine.
If good quality petrol containing non-metallic additives is not available, or if engine problems arise,
the necessary petrol additives must be added to the petrol when refuelling ⇒.
Not all petrol additives are effective. The use of unsuitable petrol additives can cause considerable
damage to the engine and catalytic converter. Metallic additives should be avoided at all times.
Petrol additives on sale that are intended to improve knock resistance or increase the octane
number can also contain metallic additives ⇒.
Volkswagen recommends genuine Volkswagen or Audi fuel additives for petrol engines. These
additives and information on how to use them are available from your Volkswagen dealership.
Natural gas engines
Run the petrol tank empty every 6 months until the indicator lamp  lights up. This is necessary to
maintain the required system function for petrol mode and fuel quality.
Natural gas
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Natural gas
Natural gas can be delivered in compressed or liquefied form.
Liquefied Natural Gas (LNGyfLVSURGXFHGE\UDSLGFRROLQJRIWKHQDWXUDOJDV7KLVGHFUHDVHVWKH
volume considerably in comparison to Compressed Natural Gas (CNGyf$YHKLFOHHTXLSSHGZLWKD
natural gas engine may not be refilled directly with liquefied natural gas as the gas would expand
too much once in the tank in the vehicle.
Vehicles fitted with a natural gas engine may therefore only be refilled and driven using
compressed natural gas ⇒.
Natural gas quality and consumption
Natural gas is available in two grades: H-gas and L-gas.
H-gas has a higher calorific value and a lower nitrogen and carbon dioxide content. The higher the
calorific value of the natural gas the lower the levels of consumption.
The calorific value and the nitrogen or carbon dioxide values may, however, vary within one quality
group. For this reason, the vehicle consumption may vary when using natural gas of the same
quality.
