The climate controls automatically maintain the selected temperature in the vehicle interior
throughout each season .
Fig. 79 Climate contro ls
We recommend the following sett ing :
• Rotate the knob¢
fig. 79@ to the right to
switch on the air conditioning .
• Set the temperature to 72
°F (22 °().
• Press the !AUTO !¢ fig . 79 button .
Using the previously recommended setting is
the quickest way to achieve a comfortable cli ­
mate in the vehicle . Th is setting shou ld there­
fore only be changed when persona l comfort
l eve ls o r ce rtain circumstances requ ire it .
The climate controls are a combination of au ­
tomatic heating and ventilation systems and a
cooling 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 tem­
pe rat ure of the air from the v ents, fan speed
(air volume) and ai r distribu tion a re also auto ­
mat ica lly adjus ted . The system a lso takes into
account strong s unshine so that manua l ad ­
justment is not necessary . So in almost all
cases,
automatic mode offers the best cond i­
tions for the comfort of the occupants at all
times of the year ¢
page 68.
Please note:
In cooling mode, relative humidity in the inte­
r ior is reduced . This prevents the w indows
from fogg ing up . When outside temperatu res
ar e l ow (temperat ures below freezing), the air
cond it ion ing (compressor) switches off auto­
matically - a ir in the vehicle interior is not de­
humid ified.
When relative hum idity and tempera tures
outside are high,
c onden sate can drip from
t he a ir cond ition ing evaporator and form a
poo l of w at er unde r the ve hicle. This is normal
and not an ind ication of a leak!
When o uts ide temperatures are low, the fan
does not swi tch to a higher speed until the
coolant has reached an adequa te tempera­
tu re, wit h the exception of the defrost set­
ting.
When ac celera ting at w ide-open throttle, t he
air condi tioning compressor is temporar ily
swi tched off to ma intain full engine power .
In order to ensure engine coo ling under ex­
t reme engine lo ads , the compressor is switch­
ed off if coolant temperatures climb too hig h . ..,.

66 Warm and cold
Functions are set by turning the rotary knob

Pollutant filter
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
dust or pollen) are greatly reduced or stop­
ped. The air is also filtered in recirculation
mode.
The pollutant 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 between the listed services.
Energy management
To prevent the battery from being discharged
and to restore the balance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched
off
¢ page 147. Heating systems in particular re­
quire a great deal of energy. If you notice , for
example, that the rear window heater is not
heating, then it has been temporarily cut back
or switched
off by energy management.
These systems are available again as soon as
the energy balance has been restored.
A WARNING ,..__
For safety reasons, it is important that all
windows are free of ice, snow, and conden­
sation. Only then is good visibility ensured.
Please familiarize yourself with the correct
operation of the air conditioning and how
to dehumidify/defrost the windows.
@ Note
- If
you suspect that the climate controls
have been damaged, switch the system
off to avoid damaging it , and have it in­
spected by an authorized Audi dealer.
- 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 .
- Climate control works most effectively if
the windows are closed. However, if the interior of a parked vehicle is extremely
hot from the sun's rays, briefly opening
the windows can speed up the cooling
process.
Setting temperature
.,. Turn the rotary knob CD¢ page 65, fig. 79
to the desired temperature setting.
To set a lower temperature, turn the rotary
knob to the left. To set a higher temperature,
turn the rotary knob to the right. There are .,..

an authorized Audi dealer when there is an
operating prob lem.
Using the climate controls economically
Economical use of the climate controls helps
to save fuel.
When climate con trol is wor king in cool ing
mode, engine performance is red uced and
fuel consumption is affected. To keep the time
the air conditioning is on as short as possib le,
you shou ld do the fo llow ing:
.,. If you wo uld like to save f uel, sw itch the air
conditioning off .
.. If you open the windows whi le driving,
switch the air conditioning off.
.,. If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win­
dows.
@ For the sake of the environment
When you save fuel, you reduce em iss ions
from the vehicle.
Rear window defogger
The rear window defogger clears the rear win­
dow of condensation .
.. Press the Iii button <=> page 65, fig. 79 to
turn the rear window defogger on and off.
The rear window defogger wor ks only when
the eng ine is r unning. The indicator light in
the button illuminates when the rear window
defogger is turned on.
The rear window defogger is switched off au ­
tomatically after approx . 10 minutes .
@ For the sake of the environment
As soon as the rear window is clear, yo u
should switc h the rea r window de fogger
off . The reduced power consumption has a
beneficial effect on f uel consumption.
