The air conditioning automatically maintains the selected temperature in the vehicleinterior
throughout each season .
Fig. 87 Climate contro ls
We recommend the following sett ing :
• Rotate the knob
Q fig . 87 @ to the right to
switch on the air conditioning .
• Set the temperature to 72 °F (22 °() .
• Press the
!AUTO ! Q fig. 87 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
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 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 a lso 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
Q page 78 .
Plea se not e:
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,
condensate 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 tapping the buttons.

Pollutant filter
The pollutant filter (particle filter) ensures
that contaminants in the outs ide a ir (such as
dust or pollen) are greatly reduced or stop­ ped . T he air is also f iltered in recircu lation
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 effect iveness is weakened by
d riving the vehicle in areas with heavily pollut ­
ed outside air, the filt er element should also
be cha nged in between the listed services.
.&, WARNING
For safety reasons, i t is impo rtant t hat all
w indows are free o f ice, snow, and conden­
sa tion . Only then is good visib ility ensured .
Please familiarize yourse lf wit h the co rrect
operation of the air conditioning and how
to de humid ify/defrost the windows.

(D 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 cl imate control system repairs re­
quire special expertise and the proper
tools. You should contact an author ized
Audi dea ler in the event of malfunct ions.
(D Tips
- To avoid adversely affecting heat ing and
cooling performance and to prevent c on­
de nsation on the w indows, the air i ntake
in front of the wi ndshield must be free of
ice, s now, and leaves.
- T he a ir com ing from the ven ts and circu­
lat ing t hrough the e ntire interio r is ex­
tra cted throug h the o utlet s lots in the
side p ane ls in the lugg age comp artmen t.
Mak e sure th at the ou tlet slots are no t
covered by clothing, e tc.
- C limate cont ro l wor ks mos t effectively if
t he win dows a re closed. Howeve r, if the
interio 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.
Setting temperature

To set a lower temperature, turn the rotary
knob to the left . To set a hig her tempe rature,
tu rn the rotary knob to the r igh t. There are
additional intermediate settings availab le to
adjust the tempe rat ure as needed .

• Set the temperature you want .
• Press the
!AUTO ! button ¢ page 75, fig. 87 .
Automatic opera tion ens ures constant tem­
perat ures in the inter ior and dehum idifies the
a ir i nside the vehicle . Air temperature, vol ­
ume, and distribution are controlled automat­
ica lly to reach or maintain the desired interio r
temperature as quickly as possib le. Fluct ua­
tions in exterior temperature and the effects
of temperature from the position of the sun
are compensated for automatica lly.
Manual air recirculation mode~
The recirculation mode prevents polluted out­
side air from entering the vehicle interior.
Sw itching on air recirculation

In recirc ulation mode, air is drawn from t he
vehicle interior, filtered, and recircula ted . We
recommend that you se lect rec irculat ion
mode
briefly ¢.&. under the following condi­
tions:
When driving thro ugh a tunnel or in a traff ic
jam so that exhaust fumes and odors canno t
enter the vehicle interior.
A WARNING
You sho uld not use the recirculation mode
for an extended period s ince no fresh air is
drawn in, and with the air co ndit ioning
switched off the windows can fog up - this
i nc reases the r isk of an accident!
A/C operation ~
Switching on A /C
• Press the IAC ! button ¢ page 75, fig. 87.
Switching A /C off

@ Tips
If the L ED in the sw itch stays on a fter A/C
operation has been switched off( = sw itch ­
ing the A/C off), there is a fault in an air
conditioning component. P lease cons ult
an authorized Audi dealer when there is an
operating problem.
Using the climate controls economically
E conomical use of the climate controls helps
to save fuel.
When climate control is wo rking in cooling
mode, engine performance is reduced and
fuel consumpt ion is affected. To keep the time
the air cond ition ing is on as short as poss ible,
you should do the following: .,,_

~ If you would like to save fuel, switch the air
conditioning off.
~ If you open the windows wh ile 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 QiP button c:> page 75, fig. 87 to
turn the rear window defogger on and off.
The rear window defogger works only when
the eng ine is running. 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 10 to 20 minutes, depend­
ing on the outside temperature.
At very low outside temperatures, the rear
window defogger can be switched on continu­
ously by push ing the
QiP button for more than
2 seconds. This remains stored unt il the igni­
tion is sw itched off . A rear window defogger
that was switched on a lso remains stored for
15 minutes after the ignition is switched off.
If the engine is restarted within these 15 m i­
nutes, the rear window defogger is act ivated
for 10 to 20 minutes, depending on outside
temperature. With a vehicle that is parked for
a short t ime, the rear w indow defogger does
not need to be manually activated again.
@) For the sake of the environment
As soon as the rear window is clear, yo u
should switch the rea r window defogger
off . The reduced power consumption has a
beneficial effect on fuel consumption.
