Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 75 °F (+23 °C).
- Press the [AUTO] button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting , as desired, to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible .
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 99 for
year-round comfort .
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up .
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle. This is
normal and does not indicate a leak. If the outside temperature
is low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle. The air is also filtered in air recirculation
mode.
The air pollutants filter must be changed at the intervals specified in
your Warranty
& Maintenance booklet, so that the air conditioner can
properly work .
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your Audi
Warranty
& Maintenance booklet. If in doubt, ask your authorized
Audi Service Advisor for advice .
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings and
does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored . _.,

En ergy management
To prevent the ba ttery from be ing discharged and to resto re the
balance of energy, compone nts which req uire la rge amou nts of
ene rgy are temporari ly c ut back or switched off~
page 249. Heating
systems in part icu lar requ ire a g reat dea l of energy . If you not ice, fo r
example, that the seat * or rear w indow heating is not heating, they
have been temporari ly cut back or switch ed off by
energy manage·
ment .
These systems are available again as soon as the energy
balance has been res tored.
& WARNING
Reduced vi sibil ity i s dangerous and can cause accidents .
• For safe driving it i s very important that all window s be free of
ice, snow and condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to
defog and defrost the windows.
• Never use the windshield w iper/washer system in freezing
weather until you ha ve warmed the wind shield first , using the
heating and ventilation system . The washer solut ion may freeze
on the wind shield and reduce vi sibility.
0 Note
• If you s uspe ct tha t the clima te cont ro l system has been damaged,
switch the system off to avoid furthe r damages, and have i t in sp ected
by a q ua lified dealersh ip.
• Repa irs to the A ud i a ir cond it ioner require special tec hnical knowl­
edge an d special tools. Cont act an au thor ized A udi dealer for assis ­
t ance .

Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases . To save fuel, you should use
the air conditioner only when necessary . Also please note the
following points:
To save fuel, turn off cooling mode by pressing the
[AC)
butto n (indicator ligh t goes out).
- In addit ion, if you open the window or the sunroof* while

Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the air qu alit y sen sor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory -installed pollutant filter or whethe r it is
necessary to switch to air recirculation. With heavy concentrations of
poll utants, the a ir condit ion ing system is switched automatically to
recirculation mode and the supply of outside air is blocked . As soon
as the concen tration of pollutants in the o utside air drops, fresh air is
supplied to the vehicle in terior again .
In the event that the windows fog up during automatic air recircula­
tion, you must press the® button immed iately.
Under certain operating conditions, automatic a ir recirculation is
switched off automatically. With o utside temperatures below about
SO °F ( +10 °(), automatic air recirculation is limited to 30 seconds .
With outside temperatures below about 30 °F (-1 °C) and the cooling
system is switched off, the automatic air recirculation is limited to 15
seconds. •
