Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro 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
i ng 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 higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip 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 specified 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 frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: the blower set ­
ting and air distribution are stored automati­
cally and ass igned to the remote control key
that you are using.
Four-zone automatic climate control: The cli­
mate contro l settings are automatica lly stor­
ed and assigned to the remote control key
that is in use .

A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear
window. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.
