Climate controls
Description
A pplies to vehicles: with three-zone cl imate cont ro l or
four-zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior. It is the most effective when the windows and
sunroof* are closed .
If the temperature inside
the parked veh icle becomes very warm, open ­
ing the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a highe r speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
d rip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals spec ified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more freq uently than specified in
your Aud i Warranty & Ma intenance booklet. If
i n doubt, as k your author ized Audi Se rvice Ad­
visor for adv ice.
K ey coded setting s
Three-zone climate control: The blower set­
ting and air distribution are stored automati­
cally and assigned to the remote control key
