Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the follow ing settings:
- Set the temperature to 75 °F (+23 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort 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 distribution are automatically
regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 105
for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
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 normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle.
The air pollutants filter must be changed at the intervals specified
in your Warranty
& Maintenance booklet, so that the air conditioner
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 autho­
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of

_________________________________________________ w_ a_ r_ m __ a_n_ d_ c_ o_ld __ _
energy are temporarily cut bac k or switched off~ page 269 .
Hea tin g sys tems in particu lar requi re a g rea t dea l of energy. If yo u
not ice, for example, that the seat * or rear w indow heating is not
heati ng, they have bee n tempora rily cu t bac k or switche d off by
energy management . These systems are avai lable a gain as soon as
the energy balance has been resto re d.
& 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 condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to defog and defrost the windows .
• 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 windshield and reduce visibility.
0 Note
• I f you suspect that the air conditioner has been damaged, turn
on ECO N and con tac t an autho riz e d Aud i deale r to hav e the system
inspected .
• R epairs to the A udi air co nd it io ner requ ir e sp ecia l te chni cal
know ledge and special tools . Contact an authorized Audi dealer for
assista nce .
[ i J Tips
• Kee p th e air in ta ke s lots (in fron t of the w inds hield) free from i ce,
snow and debris in order to maintain the proper function of the
cl im ate c ontro l sy ste m.
Controls and equip ­
ment
• T he air flowing out of the vents and throughout the vehic le's
en tire int er ior is discha rge d at the rear o f the vehicle . Make sure th at
the outlet s lots are not covered by clothin g, etc .
• Climate c ontro l wor ks mo st e ffec tively if th e windo ws and the
sunroof are closed . However, if the interior of a park ed vehicl e is
e xt re me ly hot fro m the su n's rays , briefly open ing the windows can
speed up the cooling process .•

I I irechnical data

-Warm
and cold --------------------
ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
jAUTO I button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
turned on again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system
detects polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory -installed pollutant filter or
whether it is necessary to switch to air recirculation. With heavy concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in
the outside air drops, fresh air is supplied to the vehicle interior
again.
In the event that the windows fog up during automatic air recircula ­
tion, you must press the® button immediately. Under certain operating conditions, automatic air recirculation is
switched off automatically. With outside temperatures below about
+ 10
°C, automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECON mode,
automatic air recirculation is limited to 15 seconds. •
Synchronization
One climate control setting for the passenger's and
driver's seats.
After Synchronization is set to on, all of the subsequent climate
control settings (except for seat heating*) for the driver are trans ­
ferred to the front passenger.
Synchronization is canceled when settings are adjusted on the front passenger's side. •
Center air vent
The temperature of the air leaving the center vents can be
changed to differ from the temperature setting.
Fig. 113 Display:
Center air vent
The air flow coming from the center vents can be adjusted to be
colder or warmer than the selected set temperature.

with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads on this wheel, the EDL cuts out tempo ­
rarily. The vehicle remains operational and behaves in the same way
as a vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto ­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 21. •
Ant"-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates, the wheels are prevented from spinning by adjusting the engine power to match the amount of grip available from the road
surface.
How the system works
ASR
performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 266, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test . You can activate a deactivated ASR if required
by pressing the =>
page 262, fig. 232 button . When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front-wheel drive a deactivated ASR automatically re-activates
itself at a speed of 40 mph (70 km/h) .
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 262, fig. 232. With the ASR deactivated,
the ESP check light comes on, see=>
page 18. The message ASR off
appears in the display as well. On vehicles with front-wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons . Vehicles with all -wheel drive: the ASR can be deactivated
at any speed .
The ASR should normally be activated all the time. Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
