sw itch pos ition s
The roof will slide open or tilt up at the rear as required. When the
ignition is on, you can slide the roof open or c lose it to the desired
position by turning the rotary control switch located overhead next
to the interior light. The roof is tilted open or closed by pressing or
pul ling the control switch at position®~ fig. 53.
You can still close or open the sunroof for up to ten minutes after
you have switched off the ignition with the key remaining in the igni­ tion lock. If either door is opened, powered operation of the sunroof
will be deactivated .
Contro ls and eq uip­
ment
Op ening and clo sing
S ol ar r oof *
The solar cells in the roof provide energy to operate the ventilation system for the c limate control. It is activated automatically after the
veh ic le is parked. Depending on solar i rradiation , the interior
temperature of the vehicle is lowered in the summer, in the winter
the interior is dehumidified.
So la r pr otec tion with slidi ng glass su n roof
The slid ing glass sun roof is equ ipped with an adjustable sunshade
to reduce the effects of strong sunl ight . The so lar protection can be
moved at the recessed handle to open and close it. To prevent the
vehic le interior from heating up, you should close the solar protec­
tion when you park your vehicle in the sun.
When the roof is
slid open , the sunshade is opened automatically.
When the roof is closed, the sunshade can be closed manually.
When the roof is
t ilted open , the closed sunshade is also raised at
the rear edge. But it can still be slid open or closed.
0 Note
You should always closed the sliding/tilting sunroof when you leave
your vehicle. Sudden rain can drench the interior equipment and
damage the electronic convenience features in your vehicle .
[ i ] Tips
If you park your vehicle in the sun, we recommend that you close
the sunshade .•

Warm and cold
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 -

energy are temporarily cut bac k or switched off~ page 276.
H ea tin g sys tems in particu lar requi re a g rea t dea l of energy. If yo u
not ice, for example, that the seat *, windshield * or rear window
hea ting is no t heating, they have bee n t empor arily cut b ack or
sw itched off by
energy management . These systems are availabl e
again a s soon as the ene rgy ba la nce has bee n restored .
& WARNING
Reduced visibility is dangerous and can cause accidents .
• For safe driving it is very important that all windows be free of
ice , snow and condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to defog and defrost the windows .
• Never use the windshield wiper /washer system in freezing
weather until you have warmed the windshield first , using the
heating and ventilation system. The washer solution may freeze
on the windshield and reduce visibility.
0 Note
• I f you suspect that the air conditioner has been damaged, turn
on ECO N and con tac t an authori ze d Aud i deale r to hav e the system
inspected .

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 ..
