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. _.,

Rear window defogger QW
The rear window defogger clears the rear wind ow of
condensation.
F ig . 138 Sw itc h for
re ar window d efogger
- Press t he QW switch to turn the rear window defogger o n
and off=> fig. 138 .
The rear window defogger works only when the eng ine is running .
T he light in the switch will illuminate when the defogger is on.
The rear window defogger will switch off automatically after a short time. The time the rear window defogger remains on will vary
depending on the outside temperature .
At very low outside temperatures, the rear window defogger can be switched on continuously by pushing the
[ffi) button for more than 2
seconds. This remai ns s tored unti l the ignition is switched off.
A rear window defogger that was switched on also remains stored
for 15 minutes after the igni tion is switched off . If the engine is
restarted within these 15 minutes, the rear window defogger is also
activated, depending on outside temperature. With a veh ic le that is
parked for a short time, the rear window defogger does not need to
be manua lly activated again.
Con tro ls and eq uip­
ment
ffi For the sake of th e environm ent
Turn the defogger off when the rear window is c lear . When you save
e lectricity, you save fuel. •

- To adjust the direction o f the airflow from the o utlet,
move the tab in the cen ter of the o utlet in the desired
direction . The direction of the air delivered from the
vents can be adjusted hor izontally 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 .
The air outlets to heat the rear footwell are located under the front seats.
[ i ) Tip s
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
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
ffi For the sake of th e environm ent
By reducing the amount of fue l you use, you also reduce the amount
of pollutants emitted into the air. •

• For safety reasons, you should always park your vehicle with
the selector lever in P. Otherwise, the vehicle could inadvertently roll away.
• After the engine has been switched off, the radiator fan can
continue to run for up to 10 minutes -even with the ignition
switched off. It can also switch on again after some time if the
coolant temperature rises as the result of a heat buildup or if the
engine is hot and the engine compartment is additionally heated
by the sun's rays.
0 Note
If the engine has been under heavy load for an extended period,
heat builds up in the engine compartment after the engine is
switched off -there is a risk of damaging the engine. Allow the
engine to run at idle for about 2 minutes before switching it off. •

lever for the automatic transmission is not in the P or N position.
The engine can only be started with the selector in these positions.
? Key not in vehicle
This message appears along with the symbol if the master key is
removed from the vehicle with the engine running. It is intended to
remind you (e.g. when changing drivers) not to continue the journey
without the master key.
If the master key is no longer in the vehicle, you cannot switch off
the ignition after stopping the engine and you also cannot start the engine again. Moreover, you cannot lock the vehicle from the
outside with the key.
Shift to P, otherwise vehicle can roll away. Doors do not lock if lever
