Electronic immobilizer
T he immobilizer helps to prevent unauthor­
ized use of your vehicle .
A computer chip ins ide your key automatically
deac tivates the elec tronic immobilizer when
you insert the key in the ignition lock , or on
vehicles with Convenience key*, when the key
is ins ide the veh icle. When you remove the key
from the ignition lock, or on vehicles with
Convenience key, when you remove the key
from the vehicle, the electronic immobilizer is
automatica lly activated once again.
WARNING
Always take the key with you when you
l eave the vehicle. The key can disarm the
electronic engine immobilizer and permit
an unauthorized person to start the engine
and enable operation of the vehicle sys­
tems such as power w indow or Panoramic
slid ing sunroof* leading to serious person­
al injury.
u) Tips
-The vehicle cannot be started if an unau­
thorized key is used . The vehicle may not
start if another radio device such as a key
for another vehicle or a transponder is
located on the key ring.

Warm and cold Climate control
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:
~ Set the temperature to 72 °F (+22 °C).
~ Press the !AUTO I 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 automatica lly reduce humidity and cool
the air inside your vehicle.
The air temperature, air flow and air distribu­
tion are automatica lly regu lated 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 ve hicle.
We recommend you use the
Automatic mode
¢ page 94 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 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
l y.
The a ir conditioner temporarily switches off
when you drive off from a standstill using full
throttle to save engine power.
Warm and cold 91
The compressor also switches off if the cool­
ant temperature is too high , so that the en­
gine can be adequately cooled under extreme
loads .
Air pollutants filter
The air pollutants filter (a combined particle
filter and activated charcoa l filter) reduces or
prevents outside air pollution (dust, or pollen)
from entering the vehicle. The air is a lso fil­
tered in a ir recirculation mode.
The air pollutants filter must be changed at
the interva ls specified in your Warranty
&
Maintenance booklet, so that the a ir cond i­
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 Serv ice Ad­
visor for advice .
Key coded settings
The air conditioner settings selected are auto­
matically stored and assigned to the key be ing
used. When the vehicle is started, the air con­
ditioner automa tically selects the settings as­
s igned to that key . This way every driver w ill
mainta in his/her own personal settings and
does not have to reset them manually.
If a different dr iver uses your key and changes
the air cond itioner settings, the latest adjust­
ments will erase and replace the sett ings you
have stored.
Energy management
To prevent the battery from being discharged
and to restore the balance of energy, compo­
nents which require large amounts of energy
are temporarily cut back or switched off
¢ page 225. Heat ing systems in particular re­
quire a great deal of ene rgy. If you notice , fo r
example, that the seat* or rear window hea t­
ing is not heating, they have been temporarily
cut back or switched off by
energy manage­
ment .
These systems are availab le aga in as
soon as the energy balance has been restored . .,.
