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 following settings:
- Set the temperature to 72 °F (+22 °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 126
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 . Th is
is normal and does not indicate a leak.
Controls and equip ­
ment
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 is also filtered in air recir­
culation mode.
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. _.,

Energ y man ag em ent
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 295.
Heating systems in particular require a great deal of energy. If you
notice, for example, that the seat * or rear window heating is not
heating, they have been temporarily cut back or switched off by
ene rg y m anage ment. These systems are available again as soon as
the energy balance has been res tored .
& WARNING

0 Note
• If you suspect that the air conditioner has been damaged, turn
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
know ledge and special to ols. Contact an authorized Audi dea ler for
assistance.
[ i ] T ip s
• Keep the air intake slots (in front of the windsh ie ld) free from ice,
snow and debris in order to maintain the proper function of the
climate contro l system.
• Air inside the vehicle escapes through air vents located in the
s ide tr im panels beneath the rear side windows. Make sure that the
out let slots are not covered by clothing, etc.
• Climate control works most effectively if the windows and the
Panoramic s liding sunroof* are c losed. However, if the interior of a
parked vehic le is extreme ly hot from the sun's rays, briefly opening
the windows can speed up the cooling process. •

pillars . To achieve adequate cooling, you should never close the
out lets completely .•
Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditioner only when necessary . A lso please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
- If yo u are g oing to dr ive wit h the w indows or Panorami c
sliding sunroof* open, use ECON .
- If the ve hicle is e xtremely ho t due to the heat of t he s un,
br iefly open doors and windows .
Contro ls and eq uip­
ment

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.
P lease note that vehic le interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or
dehum id ified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the [AUTO ] button in
the air conditioning controls is pressed , the system automatically
leaves the ECO N mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air q uality sensor detects increased concentrations of
pollu tants in the outside air and automatically switches
t o 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 po lluted outside air, the sensor decides whether the air
po llution can be reduced by the factory -installed pollutant filter or
whether it is necessary to switch to air recirculation. With heavy ...

Warm and cold -
-------------------'
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. •
