Deluxe automatic climate control
Applies to vehicles : wit h deluxe automat ic climat e cont ro l
Description
The climate control system can be used to set a comfort­
able temperature inside the vehicle.
The climate control system is a combination of a heating and ventila­
tion system as well a cooling system responsible for dehumidifying
and cooling the air inside the vehicle.
Th e automatic climate control system automatically maintains a
temperature once it has been set. The temperature of the air from
the vents, fan speed (air volume) and air distribution are a lso auto­
matically adjusted. The system also takes into account strong
sunlight so that manual adjustment is not necessary . So in almost all
cases,
automatic mode offers the best conditions for the comfort of
the occupants at all times of the year=>
page 97.
Please note the following :
The cooling mode lowers the humid ity level inside the vehicle. This
prevents fogging up of the windows.
In the case of high outside humidity and temperatures,
condensation
can drip from the air conditioning system evaporator and form a pool
under the vehicle . This is normal and not an indication of leaks!
At low outside temperatures, the fan automatically switches to a
higher speed when the coo lant reaches a sufficient temperature
except in the defroster position .
When starting with fu ll thrott le, the compressor of the automatic
climate control system is temporarily switched off to achieve full
eng ine power .
T o ensure engine cooling when the engine is under an extreme load,
the compressor is switched off at high coolant temperatures.
Controls and equip ­
ment Safety first
Warm and cold
Pollutant filter
The pollutant fi
lter (particle filter) ensures that impurities in the
outs ide air (e.g. dust, pollen) and odors are significantly reduced or
stopped . The air is also filtered in recirculation mode.
T he pollutant filter e lement must be changed at the intervals speci­
fied in the service plan so that the performance of the automatic
climate contro l system is not impaired.
If the effectiveness of the filter dec reases prematurely due to opera­
tion of the vehicle in areas with significant pollution, the filter
element must be changed between the specified service dates.
Key recognition
Th e cur rent automatic clima te control settings are automatically
stored and assigned to the master key.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 243. Heating
systems in particular require a great deal of energy. If you notice , for
example, that the rear window heater is not heating, then it has been
temporarily reduced or switched off by
energy management . These
systems are available again as soon as the energy balance has been
restored.
& WARNING
Traffic safety requires all window s to be clear of ic e, snow, and
condensation. Only then can good visibility be ensured . Famil­
iarize yourself with the correct operation of the automatic climate
control system as well as the proper procedure for defog-
ging/defrosting the windows. _,.

0 Note
• If you suspect that the automatic climate control system has been
damaged, switch the syst em off to avoid further damage and have it
inspected by a qualified dealership.
• Repairs to the Audi automatic climate control system requ ire
specialized knowledge and special tools . Therefore, contact an autho­
rized dealer in the even t of malfunctions.
[ i J Tips
• To avoid adversely affecting heating and cooling performance and
to prevent condensat ion on the w indows, the air intake in front of the
windshield mus t be free of ice, snow and leaves.
• The air flowing out of the vents and throughout the vehicle's
entire interior is discharged at the rear of the vehicle. Make sure that
the outlet s lots are not covered by clothing, etc.
• The automatic climate control system works most effectively if
the windows and the panorama/tilting su nroof* are closed . However,
if the interior of a parked vehicle is extremely ho t from the sun,
br iefly opening the windows can speed up the cooling process.•

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.
Controls and equip­
ment Safety first
The climate controls are a combination
of heating, ventilation and
coo ling systems, which automatically red uce humidity and cool the
air inside your vehicle .
The climate control automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatically adjusted. The

Please note the following:
T urn on the a ir cond itioner 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,
condensati on 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.
T he air conditioner temporari ly switches off when you drive off from
a standstill using full throttle to save engine power.
T he compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Du st a nd p ollen filt er
The dust and pollen filter (a combined particle fi lter and activated
charcoal filter) reduces or prevents outside a ir po llution (dust, or
pollen) from entering the vehicle.
T he dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can properly
work.
If you drive your vehicle in an area with a high degree of air pollution,
the filter may need to be changed more frequently than specified in .,.
