Several warning and indicator lamps will light up briefly as a functional check when the ignition is 
switched on. They will switch off after a few seconds.
Natural gas engines
Things to note: if the vehicle is parked for an extended period directly after refuelling, it may well 
occur that the pointer for the natural gas engine does not indicate the fuel level shown directly after 
refuelling. This does not mean that there is a leak in the system but but rather that, for technical 
reasons the pressure has been decreased in the natural gas tank.
The small arrow next to the petrol pump symbol ⇒ Fig. 115 in the display instrument shows

Switch off the engine, ignition and the mobile telephone before filling the tank and leave them 
switched off during the process ⇒.
Please read and follow the instructions for the natural gas refuelling system.
The vehicle is not constructed for use with Liquefied Natural Gas (LNGyf  ⇒. Before refilling with 
natural gas check that you are using the correct fuel ⇒ Fuel.

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

Introduction
Natural gas
Natural gas can be delivered in compressed or liquefied form.

volume considerably in comparison to Compressed Natural Gas (CNGyf   $  Y H K L F O H  H T X L S S H G  Z L W K  D  
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.
\f

The vehicle engine management will automatically adapt to the different natural gas qualities. Both 
natural gas qualities can therefore be mixed in the fuel tank. You do not need to empty the tank 
before refuelling with a different grade.
Natural gas
The vehicle can run on natural gas. Further information is available from your local Volkswagen 
dealership.
