Warm and cold
Climate control system
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It functions most effectively when the windows
are closed. If there is a build-up of heat inside the
vehicle, ventilation can help to speed up the cool-
ing process.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
coolant has reached a certain temperature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.

ZA WARNING
Poor visibility can lead to accidents.
— For safer driving, keep all windows free of
ice, snow and fog.
— Become familiar as quickly as possible with
the correct use and function of the climate
control system, especially with the defrost-
ing and defogging function.
— When the temperature is below freezing,
only use the windshield washer system after
the
windshield has been warmed by the cli-
mate control system. The washer fluid could
freeze on the windshield and impair visibili-
ty.
©) Note
— If you suspect that the climate control sys-
tem is damaged, switch the system off to

prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
— Repairs to the Audi climate control system
require special technical knowledge and
special tools. Have it inspected by an au-
thorized Audi dealer or a qualified electron-
ics store.
(@) For the sake of the environment
Reducing the amount of fuel used also re-
duces the amount of pollutants that enter the
air.
G) Tips
—To prevent interference with the heating
and cooling output and to reduce the risk of
the windows fogging over, the air intake in
front of the windshield must be free of ice,
snow, or leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.
— The flows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug-
gage compartment cover.

Deluxe automatic climate control


Fig. 78 Deluxe automatic climate control: controls
The functions can be switched on and off by
pressing the buttons or adjusted by turning the
knob. When the function is switched on, the LED
in the respective button or knob turns on.

AUTO] Automatic mode
Automatic mode maintains a constant tempera-
ture inside the vehicle. Air temperature, airflow
and air distribution are controlled automatically.
The automatic mode is turned on using the
AUTO] button. AUTO mode switches off once a
button in the climate control system is pressed.


Audi recommends pressing the [AUTO] button
and setting the temperature to 72 °F (+22 °C).


A/C} Cooling mode
The cooling mode only functions with the blower
turned on. The cooling system is turned on and
off with the [A/C] button. The air is not cooled
and humidity is not reduced when cooling mode
is switched off. This can cause fog on the win-
dows. The cooling mode switches off automati-
cally at low outside temperatures.


S$ Blower
You can manually adjust the volume of air gener-
ated by the blower to your preference by turning
the knob (4). The blower should always run at a
low setting to prevent the windows from fogging

and to ensure a continuous exchange of air inside
the vehicle. To have the blower regulated auto-
matically, press the [AUTO] button. If the win-
dows are foggy, press the & button.

ments using the dial (2).

@. To have the air distribution regulated auto-
matically, press the [AUTO] button.


The round air vents in the cockpit are adjustable
=> page 71.
To prevent the side windows from fogging over,
open the side air vents and angle them toward
the side.
< Recirculation mode
In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior > A\.
The recirculation mode can be turned on manual-
ly or automatically*.
— Pressing the <> button switches recirculation
mode on or off manually.
