2012 AUDI A5 COUPE air conditioning

Warm and cold Deluxe automatic
climate control
Description
Appl ies to vehicles: with deluxe automatic cl imate contro l
The climate control system can be u sed to set
a comfortable temperature inside the vehicle.
The climate control system is a comb inat ion
of a heating and ventilation system as well a
coo ling system respons ible for dehum idifying
and cool ing the a ir inside the vehicle.
The automat ic climate co ntrol system auto­
mat ica lly ma inta ins a temperature once it has
been set. The temperature of t he a ir from the
ve nts, fan speed (ai r volume) and air dis trib u­
tion are also au toma tic ally adjusted . The sys ­
tem a lso takes into account strong sun light so
that manua l adjustment is not necessary . So
in almost a ll cases,
automatic mode offers
the best cond itions for the comfort of the oc­
cupa nts at all t imes of the year
c;, page 81 .
Please note the following:
The cooling mode lowers the hum idi ty leve l
ins ide the veh icle. This p reven ts fogging up of
the windows .
I n t he case of high outside humidity and tem­
pe rat ures,
condensation c an drip from the air
conditioning sys tem evaporator and form a
pool under the vehicle. This is normal and not
an indication of leaks!
A t l ow ou ts ide temper atures, the f an au to­
mat ica lly switches to a higher speed when the
coolant reac hes a sufficient temperature ex ­
cept in the defroster pos ition.
W hen sta rting with full thro ttle, the compres­
sor of the automatic clima te con trol sys tem is
temporari ly switched off to achieve f ull en­
g ine power.
To ensure eng ine cooling when the eng ine is
under an extreme load, the compressor is
switched off at high coolant temperatures .

Pollutant filter
The poll uta nt fi lter ( part icle fi lter) ensures
that imp urities in t he outside air (e .g. dust,
po llen) and odors are significantly reduced or
stopped . The air is also fi ltered in recircu lation
mode.
T he poll utant fi lter element m ust be changed
at the intervals specified in the service p lan so
that the perfo rmance of the a utomatic cli­
mate control system is not impaired.
If the effectiveness of the filter decreases pre ­
maturely due to operation of the vehicle in
areas with significant poll ution, the filter e le­
ment must be changed between the specified
serv ice dates.
Key recognition
T he c urrent automatic climate contro l set ­
tings are automatically stored and assigned to
the maste r key .
Energy management
To p reven t the bat tery from being discharged
and to res to re the ba lance o f energy, compo ­
nents which require large amo unts o f energy
are temporarily cut bac k or switched off
¢ page 211. Heating systems in particular re ­
quire a great deal of energy. If yo u notice, for
example, that the rear window heater is not
heating, then it has been temporarily reduced
o r switched off by
energy management.
T hese systems a re available again as soon as
the ene rgy balance has been res to red.
.8, WARNING
T raff ic safety re quires all windows to be
clear of i ce, snow, and con densa tion . Only
the n can good v is ib ility be ensured . Famili­
a rize yourself w ith the correct operation of
the automatic climate contro l system as
well as the proper procedure for defog­
g ing/defrosting the windows .
@ Note
-If you s usp ect that the automatic cli ­
mate contro l system has been damaged,
-
sw itch t he system off to avoid further .,_
