Turning off air recirculation
- Press~ again, or
- press [AUTO], or
- press[@].
In the air recirculation mode, the air in the passenger compartment
is recirculated to prevent exhaust fumes and other pollution from
entering the vehicle. We recommend that you use the manual air
recirculation under the followi ng conditions:
• when driving through tunnels
• in a traffic jam.
& WARNING
Do not use this setting for extended periods of time . The windows
could fog up since no fresh air can enter the vehicle . If the
windows fog up, press the air recirculation button again immedi­ ately to switch off the air recirculation function or select defrost . •

- Turn the vertical thumbw hee l beside the outlet to
increase, reduce or shut down t he airflow from that
outlet.
- To adjust the direct ion o f the a irflow from the outlet,
move t he tab in t he center of the outlet in the desired
directio n. The direct ion of the air delivered from the
vents can be adjusted horizontally and vertically.
The air outle ts are actua ted either automatically or manual ly
depending on the operating mode selected. Heated or unheated
fresh ai r, or cooled air flows from the v ents.
[ i ] Tips
• When climate contro l is working, coo led air wi ll flow primarily
from out lets

© should never be completely closed.
• The air flow coming from the vents © can be adjusted to be
colder or warmer than the selected set temperature. •

[ i J Tips
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
outlets completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditione r only when necessary. Also please
n ote the following points:
- If you want to save fuel, activate ECON.
If you are going to drive with the windows open, use
ECON.
W For the sake of the environment
By reducing the amount of fuel you use, you also reduce the amount
of pollutants emitted into the air.•
Applie s to v ehicl es: with so lar slidi ng /tilt ing sunr oof
Solar blower fan /solar roof
With sufficient sunlight, the blower fan continues to
operate with solar energy to bring in fresh air after the
ignition has been switched off.
T he fan motor is operated by solar energy through the solar roof
after the ignition is turned off. Please make certain that vents ©
and © are open to achieve optimal ventilation=>
page 122, fig. 137.
Con tro ls and eq uip­
ment
The ventilation operates only with the sunroof closed or in the tilted
position .
If the vehicle was switched off in the recircu lation mode, the air
conditioning automatically switches to fresh air operation.
Solar operation is not activated at low outside temperatures. •
Windshield defogging/defrosting

and off~ fig . 138.
The windshield defogger works only when the engine is running.
The indicator light in the button illuminates when the windshield
defogger is turned on.
With a cold engine at outside temperatures below 41 °F (+5 °C) and
in !AUTO
l operation, the windshield defogger turns on automati ­
cally. Depending on outside temperature, the windshield is heated _,.

• ..__w_ a_ r_m _ a_ n_d_ c_ o_ ld __________________________________________________ _
for a maximum of 4 minutes. The temperature for the climate
control must be selected so that it is operating in the heating mode.
When selecting the program setting
@, the windshield
defogger/defroster is switched on automatically at outside temper ­
atures below 41 °F (+5 °C). Depending on outside temperature, the
windshield is heated from 2 up to a maximum of 4 minutes.
The windshield defogger is deactivate d 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
t he crack from spreading.
• We recommend that you locate an Audi dealership immediately
to have the windshield replaced. •
Rear window defogger [ml

Press t he (ffi] switch to turn the rear w indow defogger o n
and off=> fig. 139.
The rear window defogger works only when the engine is running .
The indicator light in the butto n illuminates when the rear win dow
defogger is turned on . T
he rear window defogger will switch off automatically after a short
t ime . The time the rear window defogger remains on wi ll vary
depending on the outside temperature.
At very low outside temperatures, the rear window defogger can be switched on continuously by push ing the
QW bu tton for more than 2
seconds. This remains stored unti l the ignition is switched off .
A rear window defogger that was switched on also remai ns stored
for 15 minutes after the ignition is switched off . If the engine is
r estar ted within these 15 minutes, the rear w indow defogger is also
activated, depending on outside temperature. With a vehic le that is
par ked for a short time, the rear window defogger does not need to
be manua lly activated again.
ci> For the sake of the environment
Turn the defo gger off when the rear w indow is clea r. When you save
electricity, you save fuel. •

conso le and the outle ts in the door pillars.
• In the-,!) setting, air flows from the outlets under the front seats.
• In the~ setting, air flows from outlets in the center console and
the door pil lars as we ll as from the outlets under the front seats.
To regulate air distribution automatically, switch to !AU TO].

General
The basic settings for the climate control are performed in
the(SETUP] menu.
Fig. 141 MMI display:
Setup climate control
The basic settings for the air conditioning can only be made
with MMI turned on.
- Press the !SETUP] button in the controls to access the
menu.
- Select the desired function using the control knob (driver
or passenger) in the air conditioning controls.
The following functions can be selected:
• ECON
~ page 126
• Automatic recirculation ~ page 126
• Synchronization ~ page 127
• Center air vent~ page 127
• Rear seat operation* ~ page 127
• Solar operation* ~ page 127•
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.
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 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 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 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 polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory-installed pollutant filter or
whether it is necessary to switch to air recirculation . With heavy
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 ..
