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] 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 106
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.
Controls and equip ­
ment Safety first
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 char­
coal 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 authorized
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.

(I) Tips
If the climate control system is operating in cooling mode , air flows
p rima rily from th e outlets in the center console and in the door
pillars . T o ach ieve adequa te cooling, you should never close the
ou tle ts completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, e ngine power is reduced
and fuel consumption increa ses. To save fu el, you should use
the air co nditioner o nly when necessary. Also please note the
following points :
If you want to save fuel , activate ECON .
If you are going to drive with the wi ndows open, use ECO N.
~ For the sake of the environment
By reducing t he amount of fuel you use, you also reduce the amou nt
of pollutants emitted into the air .•

windshield is heated from 2 up to a maximum of 4 minutes .
Th e windshield defogger is deactivated in ECON mode.
(I] Tips
• If a crack forms in the windshie ld due to a foreign object (e.g. a
stone chip), the defogger/defroster is not turned on. This prevents
the crack from spreading.
• We recommend that you locate an Audi dealership immediately to
have the windshie ld replaced. •

ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
" E conomy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified .
If the vehicle inter ior 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
ECON mode, and the air conditioning compressor is turned on
again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode .
We recommend that you always keep automat ic air recirculat ion ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the facto ry-insta lled pollutant fi lter or whe ther it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the air conditioning system is switched a utomat ically to
recirculation mode and the supply of outside air is blocked . As soon .,.
Vehicle care Technical data

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 th e@ button immediately.
Under certain operating conditions, automatic air recirculation is
switched off automatically. With outside temperatures below about
-8 °C and in the ECON mode, automatic air recirculation is limited to
15 seconds. •
Synchronization
One climate control setting for all seats.
With synchronization active, the driver's or the passenger's settings
are adopted for the other seats. All the other settings that were made
are transferred to the other seats. This includes all the climate
control settings right down to the heated seats.
If a different setting is selected at a "synchronized seat", synchroni ­
zation is cancelled. •
Center air vent
The temperature of the air leaving the center vents can be
changed to differ from the temperature setting.
Fig. 129 MMI display:
Center air vent
The air flow coming from the center vents can be adjusted to be
colder or warmer than the selected set temperature.
In this way you have the opportunity to have the air flow from the
center vents a little warmer or cooler, depending on the time of year.
A little cooler in the summer and a little warmer in the winter. •
