The air conditioning automatically maintains the selected temperature in the vehicle interior
throughout each season .
Fig. 78 Climate contro ls
We recommend the following sett ing :
• Rotate the knob
c::> fig. 78 @ to the right to
switch on the air conditioning .
• Set the temperature to 72 °F (22 °() .
• Press the
!AUTO I c::> fig . 78 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . Th is setting should there­
fore only be changed when persona l comfort
l eve ls o r certain circumstances requ ire it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
coo ling system which dehum idifies and coo ls
the air inside the vehicle .
The climate controls automatically maintain a temperature once it has been set. The tem­pe rat ure of the air from the v ents, fan speed
(air vo lume) and ai r distribu tion are also auto ­
mat ica lly adjusted . The system also takes into
account strong sunshine so that manua l ad ­
justment is not necessary . So in almost all
cases,
a utomatic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year

Plea se note:
In cooling mode, relative humidity in the inte­
rior is reduced . This prevents the w indows
from fogg ing up .
When relative hum idity and temperatures
outside are high,
condensation can drip from
the a ir cond ition ing evaporator and form a
poo l of water under the veh icle. This is normal
and not an ind ication of a leak!
When outside temperatures are low, the fan
does not switch to a higher speed until the coolant has reached an adequate tempera ­
tu re , with the exception of the defrost set­
t ing.
When accelerating at wide-open throttle, the
air condit ioning compressor is temporar ily
switched off to maintain full engine power.
In order to ensure engine cooling under ex­
treme engine loads, the compressor is switch­
ed off if coolant temperatures cl imb too high .
Funct ions are set by turn ing the rotary knob
or switched o n and off by tapp ing the buttons.

Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
d ust or pollen) are greatly reduced or stop­
ped. The air is also filtered in recircu lation
mode.
The po llutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi­
tioning system's performance is not adversely
affected .
If the filter's effectiveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outside air, the filter element should also
be changed in between the listed services.
A WARNING
For safety reasons, it is important that all
w indows are free of ice, snow, and conden­
sation. Only then is good visib ility ensured.
Please fam iliari ze yourse lf with the co rrec t
operation of the air conditioning and how
to de humidify/defrost the windows .
([) Note
-If you suspect that the clima te controls
have been damaged, swi tch the system off to avoid damaging it, and have it in­
spected by an authorized Audi dea
ler .
- Audi climate control system repairs re­
quire special expertise and the proper
tools . You should contact an authorized
Audi dealer in the event of malfunctions.
(D Tips
- To avoid adversely affecting heating and
cooling performance and to prevent con­
densation on the windows, the air intake
in front of the windshield must be free of
ice, snow, and leaves.
- The a ir coming from the vents and circu­
lat ing through the entire interior is ex­
tracted through the out let slots in the
side pane ls in the luggage compartment .
Make sure that the outlet slots are not
covered by clothing, etc.
- Climate contro l works most effectively if
the windows are closed. However, if the
inter io r of a par ked veh icle is ext reme ly
hot from the sun's rays, briefly opening
the windows can speed up the cooling process .
