0 Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield. When you
drive faster than 4 mph (6 km/h), the wiper arms automatically
return back to the park position and could cause paint damage to
the engine hood!
[ i ] Tips
• You can also turn on the service position, for example, if you
want to protect the windshield from icing, using a cover.
• The service position moves to
off automatically when you
operate the windshield wiper lever, or speed exceeds 4 mph (6
km/h). •

Installing wiper blade
-Install the new wiper blade in the retainer on the wiper
arm @~fig . 68 until it clicks into place on the wiper
arm.
- Place the wiper arm back against the windshield.
Clean your wiper blades regularly with a windshield washer solution
to prevent streaking. If the blades are very dirty, for example with
insects, carefully clean the blades with a sponge or a soft brush.
If the wiper blades begin to streak the windshield, this cou ld be
caused by residue left on the windshield by automatic car washes.
Fill the windshield washer container with a special solution avail -
able at your authorized Audi dealer to remove the residue. _,,.

Warm and cold
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

parked for a short time, the rear window defogger does not need to
be manually activated again.

[ i J Tip s
If the climate control system is opera ting in cooling mode, air flows

pillars. To achieve adequate cooling, you should never close the
out lets comp letely. •
Using climate control economically
Using the climate controls prudently can hel p save fuel.
When you use the air condi tioner, engine power is reduced
and fuel c onsum ption increases. T o save fuel, you should
use the a ir condit io ner onl y when necessa ry. Also please
note the fo llow ing po ints:
If you want to save fuel, activate ECON.
- If you are going to drive with the windows open, use
ECO N.
- If the ve hicle is ext remely hot due to the heat of the sun,
brie fly open doors and windows.
'£> For the sake of the environment
By reducing the amount of fuel you use, you a lso reduce the amount
of pollutants emitted into the a ir. •
