Warm and cold
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 113
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 Maintenance
& Warranty 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 Maintenance
& Warranty 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
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
