The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The cooling system prevents the windows from misting up during
winter months.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect.
Please refer to the information regarding recirculated air mode for the air-con-
ditioning system » page 112 or for Climatronic » page 115.
WARNINGFor your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. Please familiarize yourself about
how to correctly operate the heating and ventilation systems, how to de-
mist and defrost the windows, as well as with the cooling mode.
CAUTION
■ The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
Note■ The exhaust air streams out through vents at the rear of the luggage com-
partment.■
We recommend that you do not smoke in the vehicle when the recirculating
air mode is operating since the smoke which is drawn at the evaporator from
the interior of the vehicle forms deposits in the evaporator of the air condition-
ing system. This produces a permanent odour when the air conditioning sys-
tem is operating which can only be eliminated through considerable effort and
expense (replacement of compressor).

Using the air conditioning system economically
Read and observe
and on page 108 first.
The compressor on the air conditioning system uses power from the engine
when in cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.
For the sake of the environment
Pollutant emissions are also lower when fuel is being saved » page 146, Eco-
nomical driving and environmental sustainability .109Air conditioning system
Operational problemsRead and observe
and on page 108 first.
If the cooling system does not operate at outside temperatures higher than +5
°C, there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 215 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 29.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.

The cooling system operates only if the following conditions are met. The cooling system is switched on » page 110.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower switch is switched on (positions 1-4).
Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected.
The cooling system is switched off at a high coolant temperature in order to
provide cooling at a high load of the engine.
CAUTION
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when get-
ting out of the vehicle, can cause susceptible individuals to catch a cold.Note■ We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year.■
During operation of the air conditioning, an increase in engine idle speed may
occur under certain circumstances in order to ensure sufficient heating com-
fort.

Set the air outlet vents 2 and 3 » Fig. 122 on page 108 so that the air flow is
directed slightly upwards.
After pressing, an indicator light in the top right or left corner of the button
lights up, depending on which mode was last selected.
If the warning light in the top right corner of the button lights up, the Cli-
matronic operates in “HIGH”-mode.
The “HIGH” mode is the standard setting of the Climatronic.
When pressing the button again, the Climatronic switches to “LOW”-mode
and the indicator light in the top left corner lights up. The Climatronic uses on-
ly in this mode the lower blower speed. However taking into account the noise
level, this is more comfortable, yet be aware that the effectiveness of the air
conditioning system is reduced particularly if the vehicle is fully occupied.
By pressing the button again, it is changed to “HIGH”-mode.
Automatic mode can be
switched off by pressing one of the buttons for the air
distribution or by increasing/decreasing the blower speed.

Recirculation mode - Version 1
Recirculated air mode prevents polluted air outside the vehicle from getting in-
to the vehicle, for example when driving through a tunnel or when standing in
a traffic jam.
If a considerable increase in concentration of pollutants is recognised by the air quality sensor, recirculated air mode will temporarily be switched off.
If the concentration of pollutants decreases to the normal level, the air distri-
bution control is automatically switched off so that fresh air can be guided into
the vehicle interior.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.
When the automatic air distribution control is switched on, an air quality sen-
sor measures the concentration of pollutants in the drawn in air.

Conditions for the functioning of auxiliary heating (Aux. heating and ventila-
tion), hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon is not lit in the display of
the instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (aux. heating)
The auxiliary heating (aux. heating) can be used when stationary, when the
engine is switched off to preheat the vehicle and while driving (e.g. during the
heating phase of the engine).
The auxiliary heating (auxiliary heating) functions in connection with the air-
conditioning system or Climatronic.
The auxiliary heating (aux. heating) also warms up the engine. This is not valid
for vehicles with the 3.6 l/191 kW FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting
fuel from the vehicle tank. The coolant heats air flowing into the passenger
compartment (as long as the blower fan speed

The voice control system (hereinafter referred to as the system) makes it pos-
sible to use voice commands for some functions of the hands-free system.
The period of time during which the system is ready to receive voice com-
mands and to carry them out is called a dialogue. The system gives audible
feedback and guides you if necessary through the relevant functions.
Optimum understanding of the voice commands depends on several factors. › Speak with a normal tone of voice without intonation and excessive pauses.
› Avoid a bad pronunciation.
› Close the doors, windows and sliding roof, to reduce or stop disturbing exte-
rior noise.
› You are recommended to speak louder at higher speeds, so that the sound of
your voice is not drowned out by the increased ambient noise.
