through th e windshield.
- The windshie ld must not be treated with
water-repe llent materials. They can in­
crease glare under poor visibility condi­
t ions such as wetness, darkness, or when
the sun is low on the horizon . In addi­
t ion, they can cause th e windshield wip­
ers to chatter.
(D Note
- In the case of frost, check whether the
windsh ield wiper b lades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!

Warm and cold Climate controls
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climate inside the vehicle .
We recommend the following settings:
... Se lect and set a temperature between 64 °F
(+ 22 °C) and 84 °F (+28 °C).
... Press the
!AU TO ! button.
With this setting, you attain maximum com­
fort in the least amount of time. Change this
setting, as desired, to meet your personal
needs.
The climate controls are a combination of
heating, ventilation and cooling systems,
which automatically reduce humidity and cool the air inside your vehicle.
The air temperature, air flow and air distribu­
tion are automatica lly regulated to achieve
and maintain the desired passenger compart­
ment temperature as quickly as possib le.
The system automatically compensates for
changes in the outside temperature and for
the intensity of the sunlight entering the vehi­
cle. We recommend you use the
Automatic
mode c> page 81 for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity
in the vehicle. This also p revent the windows
from fogging up .
When the outside temperature is high and the
air is very hum id,
condensation from the
evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
If the outside temperature is low, the fan nor­
mally only switches to a h igher speed once
the engine coolant has warmed up sufficient ­
ly.
Warm and cold 79
T he air conditioner temporari ly switches off
when you drive off from a standstill using full
throttle to save engine power.
T he compressor also switches off if the cool­
ant temperature is too high so that the engine
can be adequately cooled under extreme
l oads.
Air pollutants filter
T he air pollutants filter (a combined particle
filter and activated charcoa l filter) reduces or
eliminates outside air pollution (dust, or pol­
l en) from entering the vehicle .
T he air pollutants filter must be changed at
the interva ls specified in yo ur Warranty
&
Maintenance booklet, so that the air condi ­
tioner can properly work.
If you drive your vehicle in an area with high
air pollution, the filter may need to be
changed more frequently than specified in
your Audi Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice.
Energy management
To prevent the battery from being discharged
and to restore the ba lance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched off c> page 167. 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
o r switched off by
energy management.
These systems are available again as soon as
the energy balance has been restored.
_& WARNING
.-----
Reduced visibility is dangerous and can
cause accidents .
- For safe driving it is very important that
all windows be free of ice, snow and con-
densation.
- Fully familiarize yourself with the proper
use and function of the heating and ven­
tilation system and especia lly how to de­
fog and defrost the windows.

conditioner automatically se lects the settings
assigned to that key. This way every driver will maintain his/her own persona l settings and
does not have to reset them manually.
(D Tips
If a d ifferent driver uses your key and
changes the air conditioner settings, the
latest adjustments w ill erase and rep lace
the settings you have stored.
