Climate controls
Controls
The air conditioning automatically maintains the selected
temperature in the vehicleinterior throughout each
se aso n.
Fig . 93 C limate co ntro ls
We recomme nd the following setting:
Rotate the knob=> fig. 93 @to th e right to switch on the
air conditioning.
Set t he temperature to 72 °F ( 22 °Cl.
Press th e !AUTO ]=> fig . 93 button.
Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle . T his setting should
therefore on ly be changed when persona l comfort levels or certain
circumstances require it .
The climate contr ols are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and coo ls the a ir inside the veh ic le .
The climate controls automa tically ma intain a temperature once it
has been set . T he temperature of the air from the vents, fan speed
(air volume) and air dis tribution are also automa tica lly adjusted . The
system also takes into account strong sunshine so that manual
adjustment is no t necessary. So in al most a ll cases,
automatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 101.
Please note :
In cooling mode, relative humidity in the interior is reduced. This
prevents the w indows from fogging up.
When relative humidity and temperatures outside are high,
conden­
sate
can drip from the air conditioning evaporator and form a poo l
of water under the vehicle . This is normal and not an indication 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
ture, with the exception of the defrost setting .
When accelerating at wide -open throttle, the air conditioning
compressor is temporarily switched off to maintain full engine
power .
I n order to ensure eng ine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high. _,,,

Functions are set by turning the rotary knob or switched on and off
by tapping the buttons. The LED in the buttons illuminates when the
function is active .

The pollutant filter (particle filter) ensures that contaminants in the
outside air (such as dust or po llen) are grea tly reduced or stopped.
T he air is also filtered in recirculation mode.
The pollutant fil ter e lement must be changed according to the inter ­
vals specified in the maintenance schedu le so that the air condi­
tioning system's performance is not adversely affected.
If the fil ter's effectiveness is weakened by driving the vehicle in
areas with heavi ly polluted outside air, the filter element should also
be changed in between the listed services .

& WARNING
Fo r safet y rea sons , it is imp ort ant that all window s are free of ice,
snow , and condensati on . Only then i s good vi sibility en sured.

0 Note
• I f you suspect that the climate contro ls have been damaged ,
switch the system off to avoid damaging it , and have it inspected by
an authorized Audi dealer.
• Audi climate control system repairs require specia l expertise and
the proper tools. You shou ld contact an authorized Audi dealer in
the event of malfunct ions.
[ i ] Tip s
• To avoid adversely affecting heating and cooling performance
and to prevent condensation on the windows, the air intake in front
of the windsh ield must be free of ice, snow, and leaves.
• The air coming from the vents and circu lating through the en tire
interior is extracted through the out let slots in the side panels in the
luggage compartment. Make sure that the outlet slots are not
covered by clo th ing, etc.
• Climate control works most effectively if the windows are closed .
However , if the interior o f a parked vehicle is extremely hot from the
sun's rays, briefly opening the windows can speed up the cooling
process. •

the vehicle's interior temperature is too great, the fan speed will
change automatically. This is done so that the desired temperature
setting is reach ed as quickly as possible .•
