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:
- Select and set a temperature between 64 °F (+22 °C) and
86 °F (+29 °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 the outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 112
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevent 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.
I f 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 eliminates 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.
These settings will differ depending if the roof is opened or closed.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
~

Warm and cold -
----------------
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.
& 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.
• Fully familiarize yourself with the proper use and function 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, switch
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
knowledge and special tools. Contact an authorized Audi dealer for
assistance.
[ i] Tips
• Keep the air intake slots (in front of the windshield) free from ice,
snow and debris in order to maintain the proper function of the
climate control system.
• Air escapes through vents under the rear window. When placing
items of clothing on the luggage compartment cover, ensure that
the openings are not covered.
Controls and equip ­
ment
• If the inside temperature is very high (for example, if the vehicle
has been parked in sun), open the windows and allow the hot air to
escape before turning on the air conditioner. •
Controls
This overview will help you to familiarize yourself with the
air conditioning controls.
