The transmitter and battery a re located in the

92 Warm and cold
Warm and cold Climate control
Description
The air conditioner is fully automatic and is
designed to maintain a comfortable and uni­
form climat e inside the vehicle .
We recommend the following sett ings :
.. Set the temperature to 72 °F (+ 22 °C).
.. Press the
!AUTO ! button.
W ith this setting, you attain maxim um com ­
fort i n the least amount of time. Change this
setting, as desired, to meet yo ur persona l
needs.
The climate controls are a combination o f
heating, venti lation and cooling systems,
which automatica lly reduce humidity and cool
the air inside your vehicle.
The air tempera ture, a ir flow and air distrib u­
tion are automatica lly regu lated to achieve
and maintain the desired passenger compart­
ment temperature as quick ly as possib le.
The system a utomatically compensates for
changes in outside temperature and for the
intensity of the sunlight entering the ve hicle .
We recommend you use the
Automati c mode
¢ page 95 for year-round comfort.
Please note the following:
Turn on the ai r cond itione r to reduce hum idity
i n the vehicle . Thi s also p revents the w indows
from fogging up .
When the outside temperature is high and the
a ir i s very hum id,
c ondensation from the
evapo rator may drip unde r the ve hicle. This is
norma l and does not indicate a leak.
I f the outside temperatu re is low, the fan nor­
mally only switches to a h igher speed once
the eng ine coolan t has warmed up sufficient­
l y.
The air conditioner tempora rily switches off
when you d rive off from a s tandstill using full
thro ttle to s ave eng ine power. T
he compressor a lso switches off if the coo l­
ant temperature is too high , so that the en­
gine can be adequately cooled under extreme
l oads.
Air pollutant s filter
The air pollutan ts f ilter (a comb ined particle
filte r and activated charcoa l filter) reduces o r
prevents outside air po llution (dust, or pollen)
from enter ing the veh icle. The air is a lso fil­
tered in a ir recirculation mode .
The air pollutants fi lter m ust be changed at
the interva ls specified in yo ur War ranty
&
Maintenance booklet, so that the a ir cond i­
tioner can properly work.
If you drive your vehicle in an area with high
air poll ution, the filter may need to be
changed more frequently than specif ied in
your Audi Warranty
& Maintenance book let. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The air conditioner settings selected are auto­
matically stored and assigned to the key be ing
used. When the vehicle is started, the air con­
ditioner automa tically selects the settings as­
s igned to that key . This way every driver will
mainta in his/her own pe rsonal settings and
does not have to reset them manually .
If a different dr iver uses your key and changes
the a ir cond itione r settings, the latest adjust ­
ments will e rase and replace the sett ings you
have stored.
Energy man agement
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
¢ page 229. Heating systems in pa rticular re­
quire a grea t deal of ene rgy.
If yo u notice , fo r
example, that the seat* or rear window hea t­
ing is not heating, they have been temporar ily
cut back or switched off by
energy manage­
ment .
These systems are availab le aga in as
soon as the energy balance has been restored . .,.
