78 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof are closed . If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process.
I n 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 water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pollutant filter removes pollutants s uch
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and function of the heating
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ shie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
-Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporarily . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.
