Driving through water on roads
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Please follow these rules to help prevent damage to your vehicle when driving through water, for
example if the road is flooded:
•Check the depth of the water before driving through it. The water level must be no higher than
the lower edge of the vehicle body ⇒.
•Do not drive faster than walking speed.
•Never stop the vehicle, reverse or switch off the engine while in water.
•Oncoming vehicles create waves that could increase the water level for your vehicle to such an
extent that it is not safe to drive through the water.
•When driving through water, always switch off the start/stop system ⇒ Pull-away assist
systems.
Technical data
 Introduction
This chapter contains information on the followingsubjects:
⇒ Vehicle identification data
⇒ Engine data
⇒ Dimensions
⇒ Performance figures
The vehicle data sticker in the service schedule or the vehicle registration documents show which
engine is installed in your vehicle.
All data in the official vehicle documents take precedence over these data. All data in this manual
apply to the basic model. The figures may be different if additional equipment is fitted, for different
models, for special vehicles and for other countries.
Volkswagen is not responsible for any vehicle damage caused by low-quality fuel, inadequate
servicing work or lack of Genuine Parts.
NOTICE
After driving through water, mud, slush etc., the brakes may react slowly and the braking
distance will be increased as the brake discs and pads will be wet, or possibly iced up in
winter.
•You can dry and de-ice the brakes by performing careful braking manoeuvres. Ensure that
you do not endanger any other road users or violate any legal regulations when doing so.
•Avoid abrupt and sudden braking manoeuvres directly after driving through water.
WARNING
•If you drive through water, parts of the vehicle, such as the engine, drive train, running
gear and vehicle electrics, could sustain severe damage.
•Never drive through salt water as salt can cause corrosion. Rinse all components that have
been exposed to salt water immediately with fresh water.

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.
NOTICE

•You will need to depress the brake pedal more vigorously than normal as the brake servo is not
working. Do not drive too close to the towing vehicle.
•Read and comply with the information and notes in the owner's manual of the towing vehicle.
Notes for the driver of the towing vehicle
•Accelerate carefully and gently. Avoid any sudden driving manoeuvres.
•Brake earlier than normal by pressing lightly on the brake pedal.
•Read and comply with any information and notes in the owner's manual of the towed vehicle.
