Opening and closing
• For security reasons, replacement keys are only available from
Audi dealers. •
Master key with remote control
The remote control allows you to lock or unlock the
vehicle electronically .
Fig. 27 Fo ld -up m aste r
k ey with r emot e
c ontr ol
To fold the key out and back in place, press the release
button=> fig. 27.
The transmitter and battery are located in the head of the remote
control. The receiver is located inside the vehicle. The maximum
effective range depends on several things . Remember , if the battery
is weak, the effective range decreases .
If you need to replace the remote contro l, or if you need to have it
repaired, you must see your authorized Audi dealer . On ly then can
you use the key again.
Personalizing the master ke y
When the ignition is turned off or when the vehicle is locked , various
convenience settings are stored automatically and assigned to the
key that was used. The settings tha t ar e ass igned to the master key
are recal led automatically when the vehicle is unlocked, when the
door is opened or when the ignition is switched on . Settings are saved for the fo
llowing systems :
• Climate control
• Central locking
• Ambient lig hting
• Windows
• Acoustic Parking System*
• Seat memory *
T he
Remote control key function must be activated in the MM I
=:> page 85, so that the settings for the driver's seat (including the
settings for the steering column and exte rior mirrors) are saved on
the master key through the seat memory when the vehicle is locked,
and are set automatically when the vehicle is un locked .
[ i ] Tips
• I f the ignition is switched on, the remote c ontr ol system is deac­
tivated.
• T he remote control system can be af fected by other systems
operating in the same frequency range close to the vehicle, such as
mobile telephones, television broadcasting stations, etc .

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

_________________________________________________ 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 .•

Automatic mode [AUTO]
The automatic mode is the standard setting for all
seasons .
- Select temperature between 60 °F ( +16 °C) and 84 °F
(+28 °C).
- Press
[AUTO ].
Automatic operation ensures constant tempera tures in the interior
and dehumidifies the air inside the vehicle. Air temperature , volume
and d is tribution are controlled automatically to reach or maintain
the desired interior temperature as quickly as possible . F luctua tions
in exterior temperature and the effects of temperature from the
position of the sun are compensated for automatically .
This operating mode works only in the adjustable temperature
range, from 60 °F (+ 16 °C) to 84 °F ( +28 °C). If a temperature below
60 ° F
(+ 16 °C) is selected, LO appears in the display . At temperatures
above 84 °F (+28 °C),
HI is displayed . At both ex treme settings,
climate control runs continuous ly at maximum cooling or heating
power . There is no temperatu re regulation. •

The air outlets to heat the rear footwell are located under the front seats .
[ i J Tip s
If the climate control system is opera ting in cooling mode, air flows
primari ly from the out lets in the center console and in the door
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. •
