84 Warm and cold
With this setting, you attain maximum com­
fort in the least amo unt of time. Change this
setting, as des ired, to meet yo ur persona l
needs.
The climate controls are a combination of heating, venti lation and cooling systems,
which automatica lly reduce hum idity and cool
the air inside your vehicle.
The climate control automatically maintains a
temperature once it has been set . The tem­
perature of the air from the vents, fan speed
(air volume) and air distribution are also auto­
mat ically adjusted . The system also takes into
account strong sunshine so that manual ad­
justment is not necessary . So in almost all
cases,
autom atic mo de offers the best cond i­
tions for the comfo rt of the occupants at all
times of the year¢
page 86.
Please note the following :
Turn on the air cond itioner to reduce hum idity
in the vehicle . Th is also prevents the w indows
from fogging up.
When the outside temperature is high and the
a ir is very hum id,
conden sation 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 eng ine coolant has warmed up sufficient­
ly .
The air conditioner temporarily switches off
when you drive off from a standstill using full
thrott le to save engine power.
The compressor also switches off if the cool­
ant temperature is too high, so that the en ­
g ine can be adequately coo led under extreme
loads.
Du st and pollen filter
The dust and pollen filter (a combined particle
fi lter and activated charcoal filter) reduces or
prevents outside air pollut ion (dust, or po llen)
from entering the vehicle . T
he dust and po llen fi lter must be changed at
the interva ls specified in your Mai ntenance
booklet , so that the air conditioner can prop­
erly work.
If you drive your vehicle in an area with a high
degree of air pollution, the filter may need to
be changed more frequently than specif ied in
your Audi Warranty
& Maintenance book let. If
in doubt, ask your authorized Audi Service Ad­
visor fo r advice .
Key recognition
The current climate contro l settings are auto ­
matically stored and assigned to the remote
key
Energy management
T o prevent the battery from being discharged
and to resto re the ba lance of energy, compo ­
nents which require large amo unts of energy
are temporarily cut back or switched off
¢ page 211. Heat ing systems in particular re­
quire a great deal of energy. If you notice, for
example, that the rear w indow heater is not
heating, then it has bee n tempora rily cut back
o r switched off by
energy managemen t.
These sys tems are available again as soon as
the energy balance has been resto red.
