The windscreen and side windows are defrosted or demisted
as quickly as possible.– To enable this mode, press the ⇒page 162, fig. 141 button.
– To disable, press the button again or select the button.The temperature is regulated automatically. The air output is increased to
maximum and most of the air comes out of outlets 1 and 2 ⇒page 167.
The air recirculation and ECON modes are switched off when the button is
pressed.Air recirculation: manual enabling
The air recirculation setting prevents fumes etc. from entering
the interior.Enabling air recirculation mode
–Press the ⇒page 162, fig. 141 ⇒ button.
Disabling air recirculation mode
– Press the button again or
– Press the button or
–Press the button.In this setting, the air in the vehicle is constantly recirculated. We recommend
using the air recirculation mode in the following circumstances:
•When driving through a tunnel or in queues of traffic, to prevent fumes
entering the interior of the vehicle.WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because no
fresh air is entering the interior of the vehicle, with the subsequent risk of
accidents.ECON Mode (economy)
ECON mode helps save fuel.– To enable, press the button ⇒page 162, fig. 141.
– To disable, press the button again or select the button.Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) saves on fuel.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air in
the interior. The windows could therefore mist up.
On diesel vehicles, the supplementary heater is switched off in ECON mode
to save fuel.
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the climate control has been switched on) this is

Air recirculation: automatic activation*
If the outside air is polluted by diesel and petrol emissions,
an air purity sensor in the vehicle will automatically switch on
the air recirculation.Enabling air recirculation mode
– Press the button
⇒fig. 142 .
Disabling air recirculation mode
– Press the button again or
– Press the button or – Press button .
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the car.
If the
air purity sensor in the air conditioning system detects a certain
concentration of fumes in the outside air, the control unit will either pass the
incoming air through the pollution filter or automatically switch on the air
recirculation. If there is a high concentration of pollution in the outside air,
the climate control automatically switches to air recirculation and the supply
of air from the outside is cut off. As soon as the level of pollution decreases,
air is fed into the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 minutes.
If the windows mist up when the automatic air recirculation is on, press the button immediately.
The automatic air recirculation switches itself off under certain circumstances
(for instance if or is selected). In “ECON” and at temperature of below
approx. 8°C below zero, the automatic air recirculation mode is limited to 12
seconds.Switching the temperature displa y from °C to °F and vice versa
The temperature display can be switched from °C (degrees
Celsius) to °F (degrees Fahrenheit) and vice versa.– Press and hold the button for recirculation mode and briefly
press the plus button of the left-hand temperature selector

168Each of the three buttons has a specific function. The numbers relate to the
air outlets ⇒page 167, fig. 143.
Air directed to windows
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets.Economical use of the climate control
Economical use of the climate control will help save fuel.Engine power is reduced and fuel consumption increases when the
climate control is in cooling mode. To ensure that the system is only
switched on when it is really necessary, please note the following
points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun roof* while driving. – If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the amount of pollutants emitted from your
vehicle.Key settings
When the ignition is switched on, the climate control settings
assigned to the key are selected automatically.The climate control settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the climate control automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them manu-
ally.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted.

•Vehicles with a diesel particulate filter must only b e fille d with VW 507 00
engine oil.•Avoid mixing this oil with other engine oils.•Only in exceptional circumstances, if the engine oil level is too low
⇒ page 230 and you cannot obtain the oil specified for your vehicle, can you
put in a small quantity of oil (once) conforming to the VW 506 00, VW 506 01,
VW 505 00, VW 505 01 or ACEA B3 / ACEA B4 specification. (up to 0.5l).Oil propertiesViscosity
The viscosity class of the oil is selected according to the diagram.
When the ambient temperature falls outside the limits of the scale for a short
period, an oil change is not required. Mono-grade oil
Single grade oils are generally not suitable for all year round use, due to
ranges of viscosity

These oils are only useful in a climate that is constantly very cold or very
warm.
Engine oil additives
No type of additive should be mixed with the engine oil. The deterioration
caused by these additives is not covered by the warranty.
Note
Before a long trip, we recommend finding an engine oil that conforms to the
corresponding VW specifications and keeping it in the vehicle. This way, the
correct engine oil will always be available for a top-up if needed.

Cooling systemLiquid coolant
The purpose of the liquid coolant is to carry heat away from
the engine. The correct amount of antifreeze is decisive in
preventing the cooling system from freezing in winter.The your vehicle's engine cooling system is filled for life at the factory, so no
coolant needs to be changed. The liquid coolant consists of a mixture of water
and anti-freeze G12++. This is a glycol-based antifreeze with anti-corrosion
additives.
Liquid coolant additive
The amount of antifreeze required depends on the temperatures to be
expected in the winter season. If the antifreeze concentration is too low the
coolant can freeze, resulting in failure of the cooling system and heater.
The cooling system is filled at the factory with the correct amount of anti-
freeze for the country concerned.
In most cases, the mixture consists of 60% water and 40% anti-freeze . This
mixture gives the required anti-freeze protection at temperatures down to -
25°C and particularly protects the metal parts of the cooling system against
corrosion. It also prevents scaling and significantly raises the boiling point of
the liquid coolant.
Countries with warm climate
The liquid coolant concentration must not be reduced by adding plain water,
even in the summer or in warm climates. The concentration of the anti-freeze
must always be at least 40%.
Countries with cold climate
If greater frost protection is required in very cold climates, the proportion of
the anti-freeze G12++ can be increased. A concentration of 60% offers anti-
