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 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 99 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 char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle. The air is also filtered in air recirculation
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 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 . _.,

• in a traff ic 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.•
Rear window defogger [Qiil ]
The rear window defogger clears the rear window of
condensation.
- Press the QW button to turn the rear window defogger on
and
off.
Th e rear window defogger works only when the engine is running. The
light in the switch will illuminate when the defogge r is on .
The rear window defogger will switch off automatically after a short time. The time the rea r window defogger remains on will vary
depending on the outside temperature.
A rear window defogger that was switched on also remains stored for
15 minu tes after the ign ition is switched off . If the engine is
restarted w ith in these 15 minutes, the rear window defogger is a lso
act ivated, depending on outside temperature. With a vehicle that is
parked for a short time, the rear window defogger does not need to
be manua lly activated again.
c£> For the sake of the environment
Turn the defogger off when the rear window is clear. When you save
electricity, you save fuel. •

Air outlets
Air distribution determines the air flow to the individual
vents.

Air outlets ® and ©
- Rotate the vertical thumb wheel beside the outlet to
increase, reduce or shut down the airflow from that
outlet .
- To adjust the direction of the a irflow from the outlet,
move the tab in the center of the outlet in the desired
direction. The direction of the air delivered from the vents
can be adjusted horizontally and vertically.

T he ai r outlets are actuated either automatically or manually
depending on the operating mode selected.
[I] Tips
• When climate control is working, cooled air will flow primarily
from out lets @ and @. To assure adequate cooling, outlets @ and
© should never be completely closed.
• T he air flow coming from the vents © can be adjusted to be colder
or warmer than the selected set temperature. •
Air outlets in the rear
Outlets in the center console
- Rotate the thumb wheel located next to the outlet to open
or close it.
- To adjust the direction of the airflow from the outlet, move the tab in the center of the outlet in the desired
direction . T he direction of the air delivered from the vents
can be adjusted horizontally and vertically.
Outlets in the door pillars
- Rotate the thumb wheel located next to the outlet to open
or close it .
- To adjust the direction of the airflow from the outlet,
mov e the tab in the center of the o utlet in the desired
direction. The direction of the air delivered from the vents
can be adjusted horizontally and vertically.
The air outlets are actuated either automatically or manually
depending on the operating mode selected. Heated or unheated
fresh air, or cooled air flows from the vents.
T he air outlets to heat the rear footwell are located under the front
seats.
[I] Tips
If the climate control sys tem is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars. To ach ieve adequate cooling, you sho uld never close the
outlets completely. •
Using climate control 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 conditioner only when necessary . Also please note the
following points:
To save fuel, turn off cooling mode by pressing the
[AC)
butto n (indicator ligh t goes out).
- In addit ion, if you open the window or the sunroof* while
driving, turn
off cooling mode by pressing the [AC] button
(indicator light goes out).
If the vehicle is extremely hot due to the heat of the sun,
briefly ope n doors and windows.
ffi For the sake of the environment
By reducing the amount of fue l you use, you also reduce the amount
of pollutants emitted into the air.•

& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhau st fume s from the engine contain carbon monoxide, a color ­
less and odorless gas. Carbon monoxid e can be fatal if inhal ed.
• Never leave the engine idling unattended . An unattended
vehicle with a runn ing engine poses a danger of personal injury or
theft .
0 Note
Avoid high eng ine speeds, fast acce lerat ion or heavy eng ine loads
w hile the engine is still cold. This cou ld damage the eng ine .
~ For the sake of the environment
To avoid unn ecessary engine wear and to reduce exhaust emiss io ns,
do not let your vehicle stand and warm up. Be ready to dr ive off imme­
diately after starting your vehicle . Maintain mo dera te speed unt il the
engine is comp letely warm . Remember, the engine performs best at
operat ing temperature. •
Stopping the engine

& WARNING
• Never turn off the engine until the vehicle has come to a
compl ete stop .
• The brake boos ter and servotronic only work when the engine
is running. With the ignition turned off , you have to apply more
for ce when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries .
& WARNING (contin u ed )
• The radiator fan can continue to run for up to 10 minute s even
a fter you have turned off the engine and removed the ignition key.
The radi ator fan can also tur n on agai n if the engine coolant heats
