•The cooling function of the air conditioning system: if the air conditioning system is set to a very
high or low temperature it will require a lot of energy, which is generated by the engine.
Therefore the temperature setting in the vehicle should not vary too much from the outside
temperature. It may be a good idea to air the vehicle before setting off and then to travel a short
distance with the windows open. The air conditioning system should then be switched on once
the windows have been closed.
•Keep the windows closed when driving at high speeds. Having the windows open increases fuel
consumption.
•Switch the seat heating off as soon as it has served its purpose.
•Switch the rear window heating off as soon as the window has defogged and is clear of ice.
Other factors that increase fuel consumption (examples):
•Fault in engine management.
•Driving in hilly regions.
Driving in a fuel-efficient manner
Fig. 102 Fuel consumption in litres per 100 km at two different outside temperatures
First read and observe the introductoryinformation and safety warnings⇒
Introduction
By adopting an economical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15 %.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less
and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you
can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its
working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to
minimise fuel consumption and emissions. The outside temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20°C (+68°F) and at -
10°C (+14°F) are shown in ⇒ Fig. 102.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
Not only is it illegal in some countries to warm up the cold engine by running it while the vehicle is
stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resistance and therefore also fuel consumption.
Ensure that any new tyres purchased have optimum rolling resistance.
Using low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils
decrease frictional resistance in the engine and spread better and more quickly, especially for cold
starts. They are especially effective in vehicles that make a lot of short journeys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil
change intervals).
When buying engine oil, always ensure that it complies with engine oil norms and has been
approved by Volkswagen.

•If vehicles are travelling towards you in the same lane.
•If the surrounding vehicles are very dirty and therefore not very reflective.
•If there is a lot of dust.

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.
NOTICE

Keep the air intake slots in front of the windscreen free of snow, ice and leaves to ensure
heating and cooling is not impaired, and to prevent the windows from misting over.

WARNING

General information on the heating and fresh air system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The required interior temperature cannot be lower than the outside temperature as the heating and
fresh air system cannot cool or dehumidify the air.
Settings for optimal road visibility
•Set blower ⇒ Fig. 112② to level 1 or 2.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller ⇒ Fig. 112③ to the defrost position.
Information on the air conditioning system
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The cooling system for the vehicle interior only works when the engine is running and the blower is
switched on.
The air conditioning system operates most effectively with the windows and the electric panorama
sliding and tilting glass roof closed. However, if the vehicle has heated up after standing in the sun
for some time, the air inside can be cooled more quickly by opening the windows and the electric
panorama sliding and tilting glass roof for a short time.
Settings for optimal road visibility
Switching the cooling system on not only reduces the temperature of the vehicle interior, but also
the humidity. This improves comfort for the vehicle occupants and prevents the windows from
misting when the outside humidity is high.
•Switch off air recirculation mode ⇒ Air recirculation mode.
•Set the blowers to the required level.
•Open and position all vents on the dash panel ⇒ Vents.
•Turn the air distribution controller to the defrost position.
•Press the button to switch the cooling system on. The indicator lamp in the button
lights up.
The cooling system cannot be switched on
The following criteria may prevent the cooling system from being switched on:
•The engine is not running.
•The blower is switched off.
•The air conditioning system fuse has blown.
•The ambient temperature is lower than approximately +2℃ (+36°F).
•The compressor has been temporarily switched off because the coolant temperature is too high.
•There is a different fault in the vehicle. The air conditioning system should be checked by a
qualified workshop.
Things to note
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator in the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak.
The windscreen may mist up after starting the engine due to residual humidity in the air
conditioning system. Switch the defrost function on in order to clear the windscreen of condensation
or mist as quickly as possible.
Vents

vehicle's specifications. The vehicle's electrical system or electronic components could be
damaged, which could lead to electrical faults, for example in the start/stop system.
•Never connect equipment that provides electricity, such as solar panels or a battery
charger, to the 12-volt socket or to the cigarette lighter to charge the vehicle battery. This
can damage the vehicle electrical system.
NOTICE

In the interests of environmental protection, the vehicle should only be washed in specially
provided wash bays. This prevents waste water contaminated with oil, grease or fuel from entering
the sewerage system. In some countries, washing vehicles anywhere else may be prohibited.
Environmentally-friendly care products should be used.
Leftover car care products should not be disposed of with ordinary household waste. Read
the manufacturer's instructions.
Washing the vehicle
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The longer substances such as insects, bird droppings, resinous tree sap, road dirt, industrial
deposits, tar, soot or road salt and other corrosive materials remain on the vehicle, the more
damage they do to the paintwork. High temperatures (for instance in strong sunlight) further
intensify the corrosive effect. The underside of the vehicle should also be cleaned thoroughly and
regularly.
Car washes
Please observe the signs on the automatic car wash. Before using an automatic car wash take
the usual precautions, such as closing all windows and folding in the exterior mirrors, in order to
avoid damage to the vehicle. You must consult the car wash operator if there are special parts on
your vehicle such as spoilers, roof luggage carrier systems or radio aerials ⇒.
The paint is hard-wearing enough for the car to be generally washed in an automatic car wash.
However, the effect on the paint depends to a large extent on the design of the car wash.
Volkswagen recommends the use of car washes without brushes.
To remove any waxy residue from the windows and to stop wipers rubbing, please note the
following ⇒ Cleaning windows and exterior mirrors.
Washing the car by hand
When washing by hand, first soften the dirt with plenty of water and rinse off as well as possible.
Then clean the vehicle with a soft sponge, a glove or a brush using only light pressure. Start with
the roof and work from the top to the bottom. Use a shampoo for very stubborn dirt only.
The sponge or glove should be wrung out thoroughly at regular intervals.
Clean the wheels, sill panels etc. last. Use a different sponge for this purpose.
Car care products can be toxic and hazardous. Unsuitable care products and incorrect
application of care products can cause accidents, serious injuries, burns or poisoning.
•The care product must be kept in its original sealed container.
•Read the manufacturer's instructions.
•Never store car care products in empty food containers, bottles or any other non-original
containers as people finding these containers may not know that they contain care
products.
•Keep children away from care products.
•The products can give off harmful fumes during use. They should therefore only be used
outside or in well-ventilated spaces.
•Never use fuel, turpentine, engine oil, nail varnish remover or other volatile fluids to wash,
clean or care for your vehicle. These substances are toxic and highly inflammable.
WARNING
Incorrect care and cleaning of vehicle parts can impair the safety features of the vehicle and
thus cause serious injury.
•Vehicle parts must be cleaned according to the manufacturer's instructions.
•Only use approved or recommended cleaning products.
WARNING
Cleaning agents that contain solvents attack the material and can cause damage.
