Fuel
 Introduction
This chapter contains information on the followingsubjects:
⇒ Petrol
⇒ Natural gas
Different engines require different fuels. The factory-fitted sticker on the inside of the tank flap
indicates the fuel type that is required for your particular vehicle.
Volkswagen recommends using low-sulphur or sulphur-free fuels, to help reduce fuel consumption
and prevent damage to the engine.
If the engine is not running smoothly or begins to judder, this can indicate poor or inadequate fuel
quality, e.g. water in the fuel. If these symptoms appear, reduce the vehicle speed immediately and
drive to the nearest qualified workshop at medium engine speeds, avoiding high engine loading. If
these symptoms occur immediately after the vehicle has been refuelled, switch the engine off as
soon as it is safe to do so and seek expert assistance. This can help to prevent further damage.

Petrol
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Petrol types
Vehicles with a petrol engine must be run on unleaded petrol in compliance with the European
standard EN 228 or DIN 51626-1 ⇒. Fuels with a maximum ethanol content of 10% (E10) can
be used for refuelling.
Petrol types are categorised according to their octane number, e.g. 91, 95, 98 or 99 RON (RON =
Research Octane Number). The vehicle may be filled with petrol that has a higher octane number
Incorrect handling of fuel can cause explosions, fire and serious burns and injuries.
•Fuel is highly explosive and inflammable.
•Never handle fuel near open flames, sparks or glowing matter (e.g. cigarettes).
•Keep naked flames, hot parts and sparks at a safe distance.
•Switch off your mobile telephone or two-way radio when dealing with fuel. Electromagnetic
radiation can generate sparks which can in turn start a fire.
•Avoid electrostatic discharge and electromagnetic radiation in the direct vicinity of fuels.
•Never spill fuel in the vehicle or in the luggage compartment.
•Comply with any relevant safety information and legislation concerning the handling of
fuels.
WARNING

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.
Safe handling of natural gas
If you can smell gas or think there may be a leak in the natural gas system ⇒:
•Stop the vehicle immediately.
•Switch off the ignition.
•Open all the doors to fully ventilate the vehicle.
•Extinguish cigarettes immediately.
•Remove items that could cause sparks or fire from the vehicle or switch them off.
•Do not drive on if you can still smell gas.
•Seek expert assistance. Have the fault rectified.
Have the natural gas system checked regularly according to the service schedule by a
qualified workshop.
