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 follow ing settings:
- Set the temperature to 75 °F (+23 °C).
- Press the !AUTO
I 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 105
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
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle.
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 autho­
rized 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.
Energy management

balance of energy, components which require large amounts of

Using climate control economically
Using the climate controls prudently can hel p save fuel.
When you use the air condi tioner, engine power is reduced
and fuel c onsum ption increases. T o save fuel, you should
use the a ir condit io ner onl y when necessa ry. Also please
note the fo llow ing po ints:
If you want to save fuel, activate ECON.
- If you are going to drive with the windows open, use
ECO N.
- If the ve hicle is ext remely hot due to the heat of the sun,
brie fly open doors and windows.
'£> For the sake of the environment
By reducing the amount of fuel you use, you a lso reduce the amount
of pollutants emitted into the a ir. •
I • •

-Warm
and cold --------------------
ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
jAUTO I button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
turned on again. •
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 quality sensor 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
whether it is necessary to switch to air recirculation. With heavy concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in
the outside air drops, fresh air is supplied to the vehicle interior
again.
In the event that the windows fog up during automatic air recircula ­
tion, you must press the® button immediately. Under certain operating conditions, automatic air recirculation is
switched off automatically. With outside temperatures below about
+ 10
°C, automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECON mode,
automatic air recirculation is limited to 15 seconds. •
Synchronization
One climate control setting for the passenger's and
driver's seats.
After Synchronization is set to on, all of the subsequent climate
control settings (except for seat heating*) for the driver are trans ­
ferred to the front passenger.
Synchronization is canceled when settings are adjusted on the front passenger's side. •
Center air vent
The temperature of the air leaving the center vents can be
changed to differ from the temperature setting.
