2012 AUDI A5 COUPE heater

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 .,_

84 Warm and cold
With this setting, you attain maximum com­
fort in the least amo unt of time. Change this
setting, as des ired, to meet yo ur persona l
needs.
The climate controls are a combination of heating, venti lation and cooling systems,
which automatica lly reduce hum idity and cool
the air inside your vehicle.
The climate control automatically maintains a
temperature once it has been set . The tem­
perature of the air from the vents, fan speed
(air volume) and air distribution are also auto­
mat ically adjusted . The system also takes into
account strong sunshine so that manual ad­
justment is not necessary . So in almost all
cases,
autom atic mo de offers the best cond i­
tions for the comfo rt of the occupants at all
times of the year¢
page 86.
Please note the following :
Turn on the air cond itioner to reduce hum idity
in the vehicle . Th is also prevents the w indows
from fogging up.
When the outside temperature is high and the
a ir is very hum id,
conden sation 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 eng ine coolant has warmed up sufficient­
ly .
The air conditioner temporarily switches off
when you drive off from a standstill using full
thrott le to save engine power.
The compressor also switches off if the cool­
ant temperature is too high, so that the en ­
g ine can be adequately coo led under extreme
loads.
Du st and pollen filter
The dust and pollen filter (a combined particle
fi lter and activated charcoal filter) reduces or
prevents outside air pollut ion (dust, or po llen)
from entering the vehicle . T
he dust and po llen fi lter must be changed at
the interva ls specified in your Mai ntenance
booklet , so that the air conditioner can prop­
erly work.
If you drive your vehicle in an area with a high
degree of air pollution, 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 fo r advice .
Key recognition
The current climate contro l settings are auto ­
matically stored and assigned to the remote
key
Energy management
T o prevent the battery from being discharged
and to resto re the ba lance of energy, compo ­
nents which require large amo unts of energy
are temporarily cut back or switched off
¢ page 211. Heat ing systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear w indow heater is not
heating, then it has bee n tempora rily cut back
o r switched off by
energy managemen t.
These sys tems are available again as soon as
the energy balance has been resto red.
.&_ WARNING ~
Reduced visibi lity is dangerous and can
cause accidents .
-
- For safe d riving it is very impor tant that
all windows be free of ice, snow and con ­
densation .
- Comp lete ly fam iliari ze yourse lf with the
proper use and function of the heating
and venti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wipe r/washer
system in freez ing weather unt il you
have warmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the w ind-
shie ld and red uce visib ility.

238 Check ing and filling
- Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine coo l down . Hot
components will burn skin on contact.
- To reduce the risk o f being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill flu ids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electr ic fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the eng ine is still warm. The cool­
ant system is pressur ized and hot coo l­
ant could spray out .
-Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri­
cal system is necessary :
- A lways disconnect the battery.
- Never smo ke or work near heaters or
open flames . Fluids in the engine com ­
partment co uld start a fire.
- Keep an approved fire ext inguisher im­
mediately available.
- T o avoid ele ctrical shock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r l ever o f automat ic trans- mission to
"P" (Park); put manua l
transmission in Neutra l.
- Always use extreme caution to p revent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wea r clothing that
will hang o r droop into the engine.
- M inim ize exposure to em iss ion and
chemical hazards
