If the cooling system is switched off, the outside air that is drawn into the vehicle is not
dehumidified. To prevent the windows misting over, Volkswagen recommends that you leave the air
conditioning (compressor) switched on. Press the button. The indicator lamp in the button
must light up.
Maximum heat output, which is needed to defrost the windows as quickly as possible, is only
available when the engine has reached its operating temperature.
Poor visibility through all windows increases the risk of collisions and accidents, which can
cause serious injuries.
•Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
•Maximum heat output, which is needed to defrost the windows as quickly as possible, is
only available when the engine has reached its operating temperature. Do not start your
journey until you have good visibility.
•Always ensure that the heating and fresh air system or the air conditioning system and the
heated rear window are used correctly in order to have good visibility.
•Never use the air recirculation mode for an extended period. If the cooling system is
switched off, the windows can mist up very quickly in air recirculation mode and reduce
visibility considerably.
•Always switch off the air recirculation mode when it is not required.
WARNING
Stale air can quickly cause tiredness and lack of concentration in the driver, which in turn can
cause collisions, accidents and serious injuries.
•Never switch off the blowers or switch on the air recirculation mode for an extended period
as this prevents fresh air from entering the vehicle interior.
WARNING
•Switch off the air conditioning system if you suspect that it has been damaged. This can
help to prevent further damage. The air conditioning system should be checked by a
qualified workshop.
•Repairs to the air conditioning system require specialist knowledge and special tools.
Volkswagen recommends using a Volkswagen dealership for this purpose.

Filling the tank incorrectly and incorrect handling of fuel can cause explosions, fire and
serious burns and injuries.
•Always ensure that the tank cap is properly closed, to prevent the evaporation and spillage
of fuel.
•Fuel is highly explosive and inflammable and can cause serious burns and other injuries.
•Fuel can spill out if the engine is not switched off or the filler nozzle is not fully inserted
into the fuel filler neck when filling the tank. This can cause fires, explosions and serious
burns and injuries.
•When filling the tank with fuel, the engine and the ignition must be switched off for safety
reasons.
•When filling the tank, always switch off your mobile telephone and two-way radio or any
other radio equipment. Electromagnetic radiation can generate sparks which can in turn
start a fire.
•Never get back into the vehicle while filling the tank. If in exceptional cases you have to
enter the vehicle, close the door and touch a metal object before touching the filler nozzle
again. This will remove any electrostatic charge from you. Failure to do so could generate
a spark. Sparks can cause a fire when filling the tank.
•Never fill the tank or fill up a spare canister near open flames, sparks or glowing matter
(e.g. cigarettes).
•Electrostatic discharge and electromagnetic radiation must be avoided when filling the
tank.
•Follow all applicable safety information provided by the filling station when filling the tank.
•Never spill fuel in the vehicle or in the luggage compartment.
WARNING
For safety reasons, Volkswagen does not recommend carrying a spare fuel canister in the
vehicle. Fuel can spill out of the full or empty canister and catch fire, especially in the event of
an accident. This could cause explosions, fire and injuries.
•If, in exceptional circumstances, you have to transport a spare fuel canister, please note
the following:
- When refilling never place the canister in or on top of the vehicle, for example in the
luggage compartment. There may be an electrostatic charge during refilling causing
the fuel fumes to ignite.
- Always place the spare fuel canister on the ground.
- When filling a spare fuel canister, place the filler nozzle as far as possible into the
filler opening.
- If the spare fuel canister is made of metal, the filler nozzle must have constant
contact with the canister in order to avoid static charging.
- Please follow all legislation concerning the use, stowage and transport of a spare
fuel canister.
- Ensure that the spare fuel canister is accordance with the industry standard, such
as ANSI or ASTM F852-86.
WARNING
•Remove spilt fuel from all vehicle components as quickly as possible in order to avoid
damage to the wheel housing, tyres and vehicle paint.
•Filling the tank with diesel in a vehicle with a petrol engine can cause serious and
expensive engine damage and cause damage to the fuel system that is not covered by any
Volkswagen guarantee. Do not start the engine under any circumstances if you have
refilled using the incorrect fuel. Seek expert assistance. The substances in these fuels can
cause serious damage to the fuel system and to the engine itself if it is switched on.

to the wheel housing, tyres and vehicle paint.
NOTICE

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

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

You will need an external aerial to use a two-way radio in the vehicle.
Any retrofit installation of electrical or electronic equipment in the vehicle will affect its vehicle type
approval. Under certain circumstances, this can negate the type approval for the vehicle.
Volkswagen has approved the vehicle for use with two-way radios subject to the following
conditions:
•Correct installation of external aerial.
•A maximum transmitting power of 10 watts.
An external aerial is needed to give the equipment its optimal range.
Check first with a qualified workshop if you wish to use a two-way radio with a transmitting power of
over 10 watts. A qualified workshop is familiar with the technical options for retrofitting. Volkswagen
recommends using a Volkswagen dealership for this purpose.
Please observe legislation and the instructions and information given in the operating manuals for
radio equipment.
Information stored in the control units
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Your vehicle is factory fitted with electronic control units which are responsible for engine and
gearbox management. The control units also monitor the function of the exhaust system and the
airbags.
These electronic control units continuously evaluate data relevant to the vehicle while the vehicle is
being driven. Only these data will be stored if there are any faults recorded or any deviations from
the specified values. This is generally displayed by the indicator lamps on the instrument cluster.
Special units are required to read and evaluate data stored in the control units.
These data are stored so that specialist workshops can diagnose and solve problems. The
following data may have been stored:
•Engine and gearbox-relevant data.
•Speed.
•Direction of travel.
•Braking power.
•Seat belt monitor.
The control units never record conversations that take place in the vehicle. It is neither possible nor
permitted to use the stored data to create movement profiles.
When the vehicle is being used, situations may arise in which the stored data (alone or in
conjunction with other information such as accident reports, vehicle damage, witness statements
etc.) can become assignable to a particular person, in which case it may be necessary to consult an
expert and use the expert's information.
In vehicles with an emergency call function via a mobile telephone or other units, the current
location can be transmitted. In the event of an accident in which the control units register that an
airbag has been triggered, the system can automatically send out a signal. This depends on your
service provider. Transmission is possible only in areas with a sufficiently strong mobile telephone
signal.
Additional functions that are contractually agreed with the customer, e.g. vehicle positioning in an
emergency, allow certain vehicle data to be transmitted from the vehicle.
If radio equipment is not secured or not properly secured in the vehicle, it could be flung
though the interior during a sudden driving or braking manoeuvre, or in the event of an
accident. This can cause injuries.
•While the vehicle is in motion, always secure two-way radios properly outside the airbag
deployment zones or stow them away safely.
WARNING
If two-way radios that are not connected to an external aerial are used, electromagnetic
radiation in the vehicle could exceed limit values and thus be a health hazard for drivers and
other vehicle occupants. This also applies to external aerials that have not been correctly
installed.
•Two-way radios should only be used in the vehicle if an external aerial is properly
connected.
