CONTROLS AND EQUIPMENT
General hints for electronic climate
control system operation
§
At low outside temperatures, the
blower motor operates only when the
engine coolant has reached operating
temperature. This does not apply to the
position.
§
In the individual settings, the air
volume, air distribution and air tempe-
ratures are automatically adjusted. Adjust
the airflow direction by moving the vent
vanes and air volume by using the
thumbwheels.
§
When the weather is warm do not
close air outlets completely.
§
Always remove leaves, snow and
ice from engine hood air inlet in front of
windshield.
§
The heater and defroster will work
more efficiently and windshield fogging
will be reduced.
§
For safe driving, unobstructed vision
is necessary. Remove snow and ice from
the windshield, the outside mirrors and all
windows before driving.
§
Under extreme driving conditions,
and engine load, the air conditioning
system may shut off temporarily to
assure sufficient engine cooling.

§
At low outside temperatures, the air
conditioner compressor will shut off
automatically.
§
When the air conditioner is on, the
interior temperatures and humidity will be
reduced. This prevents the windshield
and windows from fogging up.
§
Do not use footwells for storage. Any
stored objects will obstruct the airflow.
§
For quickest cooling of a hot interior,
leave windows open for a few minutes to
let the hot air escape.
§
To maintain even temperature levels
and maximum heating or cooling, drive
with closed windows.
§
When it is very hot and humid,
condensed water can drip off the
evaporator under the vehicle. This is
normal and does not indicate a leak.
§
The condenser should be checked
periodically for cleanliness. If clogged
with dirt or insects, the condenser should
be washed down with water.
§
If the cooled air flow decreases even
though the system is running, the fuse for
the air conditioner may be blown. Check
fuse and replace if necessary. See
page 136.
If the fuse is not blown a built-in safety
switch may have switched the system off
temporarily or completely due to a
malfunction in the refrigerant circuit. In
this case or if the fuse blows repeatedly,
have your Audi dealer locate and correct
the cause promptly.
§
If the indicator lamp to the left of the-
outside temp. – button blinks for about a
minute after switching the ignition on,
there is a fault in the system. Have
system checked by your Audi dealer.
§
Should you suspect that the air
conditioning system
damaged through outside influences
(e.g. by an accident), the system
should be checked immediately.
§
Repairs to the
conditioning system require trained
personnel and special tools. If there
should be any malfunction in the
system, contact your nearest Audi
dealer
