Warm and cold
Climate controls
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
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 117
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
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of

Warm and cold -

energy are temporarily cut back or switched off~ page 274 .
Heating sys tems in par ticular require a great dea l of energy. If yo u
not ice, for example, that the seat *, w indshield * or rear w indow
hea ting is no t heat ing, they have bee n t em por arily c ut b ack or
switched off by
energy management . These systems are availabl e
aga in as soon as the ene rgy ba lance has bee n restor ed.
& WARNING
Reduced visibility is dangerous and can cause accidents .
• For safe driving it is very important that all windows 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 wiper /washer system in freezing
weather until you have warmed the windshield first , using the
heating and ventilation system. The washer solution may freeze
on the windshield and reduce visibility .
0 Note
• If you suspect that the air conditioner has been damaged, turn
on ECO N and con tac t an autho riz e d Aud i dea le r t o hav e th e sys te m
inspected .
• Re pairs t o the A udi air co nd it io ner req uire s pecia l tec hni cal
know ledge and special tools . Contact an authorized Audi dealer for
assista nce.
[ i ] Tips
• Kee p th e air in ta ke s lots (in fron t of the w inds hield) free from i ce,
snow and debris in order to maintain the proper function of the
cl im ate c ontro l sy ste m.
Controls and equip­
ment
