Warm and cold
Climate control system
Description
Depending on the vehicle equipment, different
systems could be installed:
- manual climate control system or
- automatic climate control system"
The climate control system circu lates, warms or
cools, and removes humidity from the air in the
vehicle interior. It is the most effective when the windows and panorama glass roof" are closed. If
there is a build-up of heat inside the vehicle, ven­
tilation can help to speed up the cooling process .
Pollutant filt er
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key rec ogn ition *
The automatic climate cont ro l system* settings
are stored and assigned to the remote control
key that is in use.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar with the correct use and
function of the climate control system as
quickly as poss ible, espec ially with the de­
frosting and defogging functions.
- When the temperature is below freezing,
only use the windshield washer system after
the windsh ield has been warmed by the cli­
mate control system. The washer fluid could
Warm and c old
freeze on the windshield and impair visibili­
ty.
@ Note
- If you suspect that the climate contro l sys ­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Aud i dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Audi dea ler
or authorized Aud i Service Fac ility.
@) For the sake of the environment
- To save fuel, turn off the climate control
system cooling mode by pressing the A/C
button. This will also reduce emissions . The
cl imate control system is off when the LED
in the button turns off.
- In vehicles w ith the efficiency program*,
you can find other consumptio n information
and more economy tips

(D Tips
- To prevent interference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
fro nt of the windshie ld must be free of ice
,
snow or leaves.
- Condensation from the cooling system* can
dr ip and fo rm a pudd le of water under the
vehicle. This is norma l and does not mean
there is a leak .
- The energy management system may tem­
porarily switch off certain functions, s uch as
the seat heating* or rear window defogger .
These systems are avai lable aga in as soon
as the energy supply has been restored.

the climate control system runs continuously at
maximum cooling or heating power. There is no
temperature regulation.
Synchronization : by pressing the AUTO button
for two seconds, the temperature setting for the
driver's side is transferred to the front passeng­
er's side. This applies a temperature change to
the front passenger's side.
Be Blower
Using the regulator 8ft, you can manually adjust
the volume of air generated by the blower to your
preference.
Use the left
8ft butto n to decrease the air speed,
and use the right
8ft button to increase the air
speed .
The blower should always run at a low setting to
prevent the windows from fogging and to ensure
a continuous exchange of a ir inside the vehicle.
To have the airflow regulated automatically,
press the AU TO button.
!,.i /:,0/!,DAir distribution and vents
The air distr ibut ion can adjusted with the but­
tons. To have the air dist rib ut ion regulated a uto­
matica lly, press the AUTO button.
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con ­
sole using the r idged thumbwheels . T he levers
adjust the direction of the airflow from the vents .
To keep the front s ide windows from fogging up
in damp weathe r, we recommend opening the
side air vents and tilting them to the side.
~ MAX Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshie ld. Recirculation
mode switches off. The temperature should be
set at +72°F (22°() or highe r.
The AUTO button sw itches the defroster off.
Warm and cold
~A Recirculation mode
To switch on the recircu lation mode, press the
~A button . The lower LED in the button turns
on .
In rec ircu lation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfi l­
tered air outside the vehicle from entering the
vehicle interior. Switching recirculat ion mode on
when driving through a tunnel or when sitting in
traffic is recommended
¢ ,&..
The AU TO button or@ button switches recircula­
tion mode off.
T o switc h on the automatic recirculation mode,
press the
~A button again. The upper LED in the
button turns on. The system switches to recircu­
lation mode when driving in reverse when the en­
gine is cold. The air quality sensor that is de­
s igned for diese l and gasoline exhaust automati­
ca lly switches the recirculation mode on or off
depending on the level of pollutants in the out­
s ide air . Automatic rec irculat ion mode is time re­
stricted when cooling mode (A/C) is sw itched off
and frost temperatures are ide ntif ied.
QW REAR Rear window defogger
The rear window defogger on ly operates when
the engine is running and will be automatically
switched off after approximately 10 minutes.

- un leaded fue ls for vehicles with catalytic con­
verter may not be available;
- fuel may have a considerably lower octane rat­
ing . Improper fuel may cause engine damage;
- service may be inadequate due to lack of proper
service facilities, tools or testing equipment;
- r eplacement parts may not be readily available.
- Nav igation systems for veh icles built for the
U.S .A . and Canada will not necessarily work in
