AUDI S3 2012 Manual Online

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.

80 Warm and cold
-Never use the windshield wiper/washer
system in freezing weather until you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­
shield and reduce visibility .
(D Note
-If you suspect that the air conditioner
has been damaged, switch off the air
conditioner and contact an authorized
Audi dealer to have the system inspect­
ed .
- Repairs to the Audi air conditioner re­
quire special technical knowledge and
special tools. Contact an authorized Audi
dealer for assistance.
@ Tips
-Keep the air intake slots (in front of the
windshield) free from ice, snow and de-
Controls
bris in order to maintain the proper func­
tion of the climate control system.
- Air escapes through vents under the rear
window. When placing items of clothing on the luggage compartment cover, en­
sure that the openings are not covered.
- If the inside temperature is very high
(for example, if the vehicle has been
parked in sun), open the windows and al­
low the hot air to escape before turning
on the air conditioner .
- A sensor in the grill provides the air-con­
ditioning system continuously with read­
ings of current outside temperature . So
that the air-conditioning can operate at maximum efficiency, the area below the
front license plate holder must not be
covered .
This overview will help you to familiarize yourself with the air conditioning controls.

will go
c:> & .
• Move the steer ing whee l to the desired po-
s it ion.
• Push the lever back up as far as it will go.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steer­
i ng wheel. If you cannot si t more than 10 in­
ches (25 cm) from the steering whee l, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering whee l.
F or detai led information on how to adjust the
driver's seat, see
c:> page 63, Power seat ad­
justment.
