Heating and cooling

The compressor also switches off if the coolant temperature is

excessively high, to ensure adequate engine cooling under extreme

loads.

Deluxe automatic air conditioner

Applies to vehicles: with deluxe automatic air conditioner

Description

Pollution filter

The pollution filter (a particle filter) serves as a barrier against impu-

rities in the outside air, including dust and pollen, and odours. The

air is also filtered when the air recirculation mode is activated.

The air conditioner can be used to set a comfortable inte-

rior temperature in the vehicle.

The air conditioner provides heating and ventilation and also cools

and dehumidifies the air inside the vehicle.

For the air conditioner to work with maximum efficiency, the pollu-

tion filter element must be replaced at the intervals specified in the

Service Schedule.

The air conditioner is fully automatic and will maintain the desired

temperature at a constant level. To achieve this, the temperature of

the air supplied to the interior, the blower speed (volume of air

delivery) and the air distribution are regulated automatically. The

system also allows for the effect of strong sunlight, so there is no

need for manual adjustment. For these reasons it is advisable to use

the automatic mode for the comfort of all the passengers in virtually

all conditions throughout the year ⇒ page 93.

If the vehicle is driven in areas with a high level of air pollution and

the filter is no longer fully effective, it may be necessary to change

the filter element more frequently.

Key-coded settings

The currently selected air conditioner settings are automatically

stored and assigned to the remote control key.

Please note:

Power management

The humidity of the air is automatically reduced when the system

cools the interior of the vehicle. This helps to prevent condensation

on the windows.

To prevent the battery from becoming discharged and to maintain

the necessary power level, the system will temporarily shut off the

electrical components that are using a lot of power, or reduce the

current they are consuming ⇒ page 192. Heating systems in partic-

ular use a large amount of electrical power. If you notice, for

instance, that the rear window heater is not working, it may have

been temporarily switched off by the power management function,

or regulated to a lower heat output. These systems will be available

again as soon as sufficient electrical power is available.

If the humidity and temperature outside the vehicle are high,

condensation can drip off the evaporator in the air cooling system

and form a pool underneath the vehicle. This is normal and does not

indicate a leak.

If the outside temperature is low, the blower normally only switches

to a higher speed once the coolant has warmed up sufficiently (this

does not apply to the defrost setting).

In order to achieve maximum engine power, the air conditioner

compressor is temporarily switched off when pulling away from a

standstill with full throttle.

WARNING

Controls

For safety reasons it is important that all the windows are kept

free of ice, snow and condensation. These can cause poor visibility

and lead to an accident. Please familiarise yourself with the oper-

ating controls for the air conditioner, including the demist/defrost

functions for the windows.

The controls for the air conditioner at a glance.

Caution

• If you suspect that the air conditioner is damaged, switch it off

to prevent further damage and have the system checked by a quali-

fied workshop.

• Repairs to the Audi air conditioner require specialist knowledge

and special tools. For this reason, please contact a qualified work-

shop if the system is not working properly.

Note

• Keep the air intake slots in front of the windscreen clear of snow,

ice and leaves to ensure unimpaired heating and cooling, and to

prevent the windows misting over.

Fig. 103 Controls for deluxe automatic air conditioner

• The air from the outlets flows through the passenger compart-

ment and out through the slots at the rear of the vehicle. Do not

cover these slots with clothing or other objects.

The functions can be set by turning the rotary control and are

switched on and off by briefly pressing the buttons. The LEDs in the

buttons light up when the function is switched on.

• The air conditioner operates most effectively with the windows

and the tilting panorama 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 for a short time.

The automatic mode maintains a constant temperature inside the

vehicle and dehumidifies the air. Air temperature, air delivery and

air distribution are regulated automatically to reach the desired

interior temperature as quickly as possible, and then to maintain

this temperature. The system automatically compensates for any

variations in the outside temperature and for the effect of direct

sunlight.

The rotary control is also used to adjust the blower speed, air distribution

and seat heating.

Note

The grille on the control console ⇒ page 92, fig. 103 must be kept

free. Please ensure that it is not covered by stickers or similar. Meas-

uring sensors are located behind it.

The automatic temperature regulation only operates at temperature

settings between +16 °C and +28 °C. If a temperature below +16 °C

is selected, LO appears on the display. If a temperature above +28 °C

is selected, the display will show HI. In the two extreme settings the

air conditioner operates continuously with maximum cooling or

heating output, and the temperature is not regulated

automatically.

WARNING

For reasons of safety you should not leave the air recirculation

switched on for too long. This mode prevents fresh air from

entering the vehicle, so the windows can mist over if the air

Heating and cooling

The rear window heating only works when the engine is running. An

indicator lamp in the button lights up when the rear window heater

is switched on.

– Turn the rotary control to the desired setting.

You can use the air distribution setting to select the air outlets you

wish to activate. In setting  all the air is directed to the windows,

in setting  the air is directed to the driver (or passenger), and in

setting  to the footwells. In addition to this there are several other

possible combinations, allowing you to adjust the air distribution to

suit individual requirements.

Depending on the outside temperature, the rear window heating

switches off automatically after about 10 to 20 minutes.

The rear window heating can be switched on permanently by

pressing the  button for longer than two seconds. It will then

remain on until the ignition is switched off. When the rear window

heating is switched on, this setting will remain activated for 15

minutes after switching off the ignition.

If the engine is started again during this period of 15 minutes, the

rear window heating will be switched on for about 10 to 20 minutes,

depending on the exterior temperature. This means you do not have

to manually switch on the rear window heating again if the vehicle

has only been parked for a short time.

adjusted horizontally and vertically using the adjuster in

the centre of each outlet grille.

Note

If the LED in the AC button should continue to light up when the AC

mode has been switched off (i.e. the air conditioner has been

switched off) this is due to a defect in one of the air conditioner

components. If a malfunction should occur, please contact a quali-

fied workshop.
