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 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 113
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 Maintenance
& Warranty 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 Maintenance
& Warranty 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.

(+28 °C) .
-Press [AUTO]~ page 112, fig. 109.
Automatic operation ensures constant temperatures in the interior and dehumidifies the air inside the vehicle . Air temperature, volume
and distribution are controlled automatically to reach or maintain
the desired interior temperature as quickly as possib le. Fluctuations
in exter ior temperature and the effects of temperature from the
position of the sun are compensated for automatica lly.
This operating mode works only in the adjustable temperature range, from 60 °F ( + 16 °C) to 84 °F ( +28 °C). If a temperature below
60 °F (+16 °C) is se lected,
LO appears in the display. At temperatures
above 84 °F (+28 °Cl,
HI is displayed. At both extreme settings,
climate control runs continuously at maximum cooling or heating
power. There is no temperature regulation. •

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] 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 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:
- If you want to save fuel, activate ECON.
- If you are going to drive with the windows open, use
ECON.
If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
~ 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. •
Controls and equip­
ment
App lies to vehic les: with solar sliding/ti lt ing sunroof
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.
The blower 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 118.
The v entilation operates only with the sunroof closed or in the tilted
position.
If the vehicle was switched off in the recirculation mode, the air
conditioning automatically switches to fresh air operation.
Solar operation is not activated at low outside temperatures. •

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 vehic le interior temperature cannot be lower than
the outs ide temperature in the ECON mode . The air is not cooled or
dehumidified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the !AUTO
I button in
the air conditioning controls is p ressed, the system automatically
leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects incre ased concentratio ns of
pollutants in the outside air and aut omatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior .
I f the
air qualit y sensor located in the air conditioning system
detects po lluted outside air, the sensor decides whether the air
pol lution can be reduced by the factory -installed po llutant filter or
whe ther it is necessary to swi tch to air recirculatio n. With heavy
concentrations of pol lutants, the air conditioning system is
sw itched automatically to rec irculation mode and the supp ly of
outside air is blocked . As soon as the concentration of pollutants in
the outside a ir drops, fresh air is supp lied to the vehic le inte rior
aga in.
I n the event that the windows fog up during automatic air recircu la ­
t ion, you must press the® button immed iately.
Under certain operating conditions , automatic air recircu lation is
sw itched off automatically. With outside temperatures be low about
+10 °C , automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECO N mode,
automatic air recirculation is limited to 15 seconds .•
Synchronization

With synchronization active, the driver 's or the passenger's settings
are adopted for the other seats . Al l the other settings that were
made are trans ferred to the other seats. This includes all the c limate
control settings right down to the heated seats.
I f a differen t setting is selected at a "synchronized seat", synchroni ­
z ation is cancelled .•

& WARNING
• The rear-view camera has blind spots , in which objects cannot
be detected . Be especially careful to check for small children and
animals before backing up . Small children and animals will not
always be detected by the sensors.
• The Audi Parking System is not a substitute for being careful
and alert when backing up . Be especially careful during parking
and similar maneuvers . Always watch where you are driving and
make sure that nothing is in the way.
• Remember that low obstacles which have already been
signaled may pass below the system 's sensing zone when the
vehicle is backing up . The fact that the signal stops does not mean
that you have cleared the obstacle . When the signal stops , impact
is imminent . Objects such as trailer hit ches, chains , narrow posts
& WARNING (continued )
or fences covered by a thin layer of paint may not always be
detected by the sy stem. They can still damage your vehicle
without warning .
• Always make sure that the volume and frequency of the chime s
is adjusted so that you can easily hear the acoustic distance signal
even if the radio is playing , the air -conditioner blower is on High or
there is a high level of outside noise .
- Check the settings whenever someone else has driven the
vehicle before you .
• Improper reliance on the Audi Parking System can cause colli ­
sions and serious personal injury .
- Never rely only on parking assi st w hen changing backing up .
- Always check rear view mirrors to make sure it is safe to back
up .
