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.

b)
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down in
traffic, accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular, especially
when driving up or down hills and inclines.
•The steering, all driver assist systems and brake assist systems will not function if the
engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and
breaking down.
WARNING
•To avoid damage to your vehicle, always observe the indicator lamps and associated
warning texts.
•Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt
fuel to enter the exhaust system. This could cause damage to the catalytic converter!

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.

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.

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 (LNG) is produced by rapid cooling of the natural gas. This decreases the
volume considerably in comparison to Compressed Natural Gas (CNG). A vehicle equipped with a
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.
•Before filling up with petrol, check whether the fuel corresponds to the vehicle's
requirements according to the fuel standard information at the pump.
•Only use fuel that complies with EN 228 or DIN 51626-1 and has the correct octane
number. Otherwise, the engine and the fuel system can suffer considerable damage. The
engine can also lose power or fail.
•The use of unsuitable petrol additives can cause considerable damage to the engine and
catalytic converter.
•If, in an emergency, you have to use petrol with an octane number lower than the
recommended number, drive at medium engine speeds and avoid high engine loading.
Avoid high engine speeds and heavy engine loads. Failure to do so can result in engine
damage. Fill the tank with petrol with the correct octane number as soon as possible.
•Fuels that are identified at the fuel pump as containing metallic additives may not be used.
LRP fuel (lead replacement petrol) also contains high concentrations of metallic additives.
Risk of engine damage!
•Just one tankful of leaded fuel, or fuel containing other metallic additives, can seriously
impair the efficiency of the catalytic converter and can also cause considerable damage to
the catalytic converter and engine.

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.

Switch off the engine and wait a few minutes for the engine oil to flow](/img/18/40259/w960_40259-136.png)
With the engine at operating temperature, park the vehicle on a level surface to ensure
that the engine oil reading is correct.
Switch off the engine and wait a few minutes for the engine oil to flow back into the sump.
Open the bonnet .
Identify the engine oil filler cap and oil dipstick. The engine oil filler opening bears the
symbol on the cap and the oil dipstick has a coloured handle. If you cannot find the cap
and dipstick please contact a qualified workshop.
Pull the dipstick out of the guide tube and wipe it off with a clean cloth.
Insert the oil dipstick into the guide tube again as far as it will go. If there is a marking on
the oil dipstick, this marking must fit in the corresponding groove at the top end of the
guide tube when inserting.
After reading the oil level, push the oil dipstick back into the guide tube as far as it will go.
Unscrew the engine oil filler opening cap .
Using only the engine oil approved by Volkswagen expressly for this engine, top up the oil
in small gradual amounts (no more than 0.5 l).
To avoid overfilling, wait for approximately one minute after each pour to allow the engine
oil to flow into the oil sump up to the marking on the engine oil dipstick.
Read the engine oil level from the dipstick again before refilling with a further small
quantity of engine oil. Never overfill engine oil .
After the refilling procedure, the engine oil level should be at least in the centre of area Ⓑ,
but never above area Ⓐ .
After refilling, screw the engine oil filler cap back on correctly.
Reinsert the oil dipstick correctly into the guide tube as far as it will go.
Close the bonnet correctly .
Checklist
Carry out the steps in the specified order ⇒:
Pull the dipstick out again and read the engine oil level on the dipstick as follows: Ⓐ: do not
refill oil . Proceed to step 15. Ⓑ: oil can be refilled (approximately 0.5 l). Proceed to step 8
or 15. Ⓒ: oil must be refilled (approximately 1.0 l). Proceed to step 8.
The engine oil level must never be above area ⇒ Fig. 121Ⓐ. Otherwise oil can be drawn in
through the crankcase breather and escape into the atmosphere via the exhaust system.
Engine oil consumption
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Engine oil consumption can vary from engine to engine and can change during the working life of
an engine.
Depending on how you drive and the conditions in which the car is used, oil consumption can be up
to 1.0 litre/2,000 km – and is likely to be higher for the first 5,000 km for new vehicles. The engine
oil level must therefore be checked at regular intervals, preferably when refuelling and before long
journeys.
When the engine is working hard the oil level must be kept within the area shown in ⇒ Fig. 121Ⓐ,
for instance during long motorway cruising in summer or climbing mountain passes.
Engine oil can ignite if it comes into contact with hot engine components. It can cause fires,
burns and other serious injuries.
•If engine oil is spilt on cold engine parts it can heat up and ignite when the engine is
running.
•Always ensure that the engine oil filler cap is securely tightened after refilling, and that the
dipstick is properly inserted back into the guide tube. This will prevent the engine oil from
draining out on to hot engine components when the engine is running.
WARNING
•Do not start the engine if the engine oil level is above area ⇒ Fig. 121Ⓐ. Seek expert
assistance. The catalytic converter and the engine could otherwise be damaged.
•When refilling or changing operating fluids please ensure that the fluids are in the correct
container. Incorrect operating fluids can cause serious functional problems and engine
damage.
