The compressor also switches off if the coolant temperature is  
excessively high, to ensure adequate engine cooling under extreme

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.

Pollution filter  
Description  
The pollution filter (a combined particle filter and activated charcoal  
filter) serves as a barrier against impurities in the outside air,  
including dust and pollen, and against unpleasant smells. The air is  
also filtered when the air recirculation mode is activated.  
The air conditioner is designed to keep the passenger  
compartment at the temperature you find most comfort-  
able at all times of the year.  
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 provides heating and ventilation and also cools  
and dehumidifies the air inside the vehicle.  
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 101.  
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.

Automatic recirculation  
If the outside air is polluted, an air purity sensor in the  
vehicle will automatically switch on the air recirculation.  
To prevent fumes, etc. in the outside air from entering the interior,  
we recommend that the automatic air recirculation should be  
switched on at all times.  
If the air purity sensor in the air conditioner 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 air conditioner automatically  
switches to air recirculation and cuts off the supply of air from the  
outside. As soon as the level of pollution decreases, air is fed into  
the vehicle from the outside again.

Heating and cooling  
The automatic air recirculation can switch itself off in certain condi-  
tions. If the outside temperature is less than about +10 °C, the auto-  
matic air recirculation will only operate for 30 seconds. If the air  
conditioner is switched to the ECON mode, or if the outside temper-  
ature is less than about -1 °C, the automatic air recirculation will  
only operate for 15 seconds.  
The auxiliary heating system can be used both when the vehicle is  
stationary and when driving (to provide extra heat while the engine  
is warming up).  
The auxiliary ventilation also operates independently of the  
engine. This feature can be used to cool the interior with the blower  
when the vehicle is left parked in the sun.  
The system will automatically activate either the auxiliary heating or  
the auxiliary ventilation mode, depending on the actual tempera-  
ture measured inside the car and the temperature you have set with  
the air conditioner controls. It is possible to alter the temperature  
setting while the auxiliary heating/ventilation is running.  
Applies to vehicles: with deluxe automatic air conditioner plus  
Synchronisation  
The air conditioner settings can be synchronised for all  
passengers.  
Switching on and off  
When the synchronisation function is on, the driver's settings are  
also applied to the front passenger or vice versa. Any subsequent  
changes to the air conditioner settings (except for the seat heating*)  
are also applied to the other occupant.  
There are two different ways of switching on the auxiliary  
heating/ventilation system.  
• Immediate start: You can switch the auxiliary heating/ventilation  
on and off at any time in the MMI Car menu ⇒ page 109. You can  
also switch the system on and off using the remote control  
⇒ page 111.  
You can still change the setting on the “synchronised” side (this will  
deactivate the synchronisation function).  
• Switching on via timer: You can programme various start times  
using the timers ⇒ page 110. However you must first activate the  
timer before the auxiliary heating/ventilation system will switch on  
automatically.  
Auxiliary heating and auxiliary  
ventilation  
The auxiliary heating/ventilation will switch itself off at the end of  
the programmed running time. The running time can be set to 15,  
30, 45 or 60 minutes ⇒ page 111.  
Applies to vehicles: with auxiliary heating - under development at the time of printing  
Description  
The auxiliary heating and ventilation systems heat and  
cool the interior independently of the engine.  
WARNING  
The auxiliary heating works in conjunction with the air condi-  
tioner system, but does not rely on heat from the engine. Instead of  
this, the system burns fuel. The system's main function is to warm  
up the interior of the vehicle and to defrost the windows in cold  
weather.  
• The auxiliary heating must not be allowed to run when the  
vehicle is in a confined space because it can give off toxic fumes.  
• To avoid any possible fire risk, never have the auxiliary heating  
switched on when refuelling the vehicle.  
• Because of the high temperatures which occur when the auxil-  
iary heating is running, make sure when parking the car that the
