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 follow ing settings:
- Set the temperature to 75 °F (+23 °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 117
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. 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 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.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of

Warm and cold -
--------------------------------J
[ 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

-Press the@ button to turn the windshield defogger on
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
Fig. 13 9 Sw itch for
r ea r wi ndow defo gger
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. •

Stopping the engin e
-Turn the ignition key to position ©~ page 130, fig. 145.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries .
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immediately after hard or extended driving.
Keep the engine running for approximately two minutes to prevent
excessive heat build-up.•
