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

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.

Charging, replacing, disconnecting and connecting the vehicle battery
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Charging the battery
The vehicle battery should be charged by a qualified workshop, as the technology used in factory-
fitted batteries requires voltage-limited charging ⇒. Volkswagen recommends using a
Volkswagen dealership for this purpose.
Replacing a vehicle battery
The battery has been developed to suit the conditions of its location and has special safety
features. If a vehicle battery has to be replaced, discuss the electromagnetic compatibility, size and
necessary servicing, output and safety requirements for the new vehicle battery with a Volkswagen
dealership before purchase. Volkswagen recommends that the vehicle battery is changed by a
Volkswagen dealership.
Only maintenance-free vehicle batteries compliant with the standards TL 825 06 and VW 7 50 73
should be used. These standards must be dated April 2008 or later.
Vehicles with start/stop system ⇒ Pull-away assist systems are equipped with a special vehicle
battery. These vehicle batteries may only be replaced by a vehicle battery with the same
specifications.
Disconnecting the vehicle battery
Please note the following if the vehicle battery has to be disconnected from the electrical system in
the vehicle:
•Switch off all electrical consumers and the ignition.
•Unlock the vehicle before disconnecting the battery in order to avoid triggering the alarm.
•First disconnect the negative cable and then the positive cable ⇒.
Connecting the vehicle battery
•Switch off all electrical consumers and the ignition before reconnecting the vehicle battery.
•First reconnect the positive cable and then the negative cable ⇒.
Various indicator lamps may light up after the vehicle battery has been connected and the ignition is
switched on. They will go out if you drive a short distance at a speed of 15–20 km/h (10–12 mph). If
the indicator lamps remain lit up, the vehicle should be checked by a qualified workshop.
If the vehicle battery was disconnected for long periods, the system may not able to calculate or
correctly display the time when the next service is due ⇒ Instruments. Comply with the maximum
permissible service intervals ⇒BookletService schedule,.
Automatic switch-off for electrical consumers
The intelligent vehicle electrical system automatically implements a range of measures to prevent
the battery from discharging under high loads:
•The idling speed is increased so that the alternator provides more electricity.
•The performance of large electrical consumers may be reduced or they may be switched off
completely.
•The power supply to the 12-volt socket and the cigarette lighter is interrupted temporarily while
the engine is being started.
The vehicle electrical system cannot always prevent the vehicle battery from discharging. For
example when the ignition is switched on for an extended period with the engine off, or when the
side or parking lights are on when the vehicle is parked for an extended period.
Any work on the vehicle battery can cause serious chemical burns, explosions and electric
shocks.
•Always wear eye protection and protective gloves.
•Electrolyte is very aggressive. It can burn the skin and can cause blindness. When
working with the battery, protect your hands, arms and particularly your face from acid
spillages.
•Never tilt the vehicle battery. Electrolyte may spill out of the battery vents and cause
chemical burns.
•Never open a vehicle battery.
•If acid is splashed onto your skin or into your eye, rinse immediately for several minutes
with cold water. Then consult a doctor immediately.
•If acid is swallowed, consult a doctor immediately.
WARNING

direction of the arrow. Push it on until it engages ⇒ Fig. 127Ⓑ. The wiper blade must be in the
tilted position (arrow Ⓐ).
•Place the wiper arm back onto the rear window.
Wax deposits on the windscreen and rear window could cause the wiper blades to rub.
Remove wax residue using a special cleaning product or cleaning cloths.
Waxing and polishing the vehicle
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Waxing
Waxing protects the paintwork. You will need to re-wax the vehicle with a good hard wax if water
no longer clearly forms small drops and runs off the paintwork when it is clean.
Even if a wax solution is used regularly in the car wash, Volkswagen recommends protecting the
paint with a coat of hard wax at least twice a year.
Polishing
Polishing is only necessary if the paint has lost its shine, and the gloss cannot be brought back by
applying wax.
The car must be waxed after polishing if the polish used does not contain wax compounds to seal
the paint.
Cleaning and caring for chrome and aluminium trim parts
First read and observe the introductoryinformation and safety warnings⇒
Introduction
•Use a damp, clean, lint-free and soft cloth to clean the surfaces.
•For heavy soiling use a special solvent-free cleaning product.
•Polish the chrome and aluminium trim parts using a soft, dry cloth.
Worn or dirty windscreen wiper blades reduce visibility and increase the risk of accidents and
severe injuries.
•Therefore, always change windscreen wiper blades if they are damaged or worn and no
longer clean the windscreen properly.
WARNING
•Damaged or dirty windscreen wipers can scratch the windscreen.
•Detergents containing solvents, hard sponges and other sharp objects can damage the
graphite coating.
•Do not use fuel, nail varnish remover, paint thinner or similar products to clean the
windows.
NOTICE
•In order to avoid damage, painted parts with a matt finish, plastic parts, headlight lenses
and the tail lights should not be treated with polish or hard wax.
