Warm and cold Climate control system
Description
App lies to vehicles: with three-zone climate control or four ­
zone a utomat 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 sun­
roof* are closed .
If the temperature inside the
parked vehicle becomes very warm, opening the
window briefly will speed up the cooling process.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensat ion from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
T he air pollutants filter must be changed at the
intervals specified in your Warranty
& Mainte­
nance booklet, so that the air conditioner can
properly work .
If you drive your vehicle in an area with high air pollution, the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet . If in doubt, ask
your authorized Audi Service Advisor for advice .
Key coded settings
Three-zone climate control: The blower setting
and air distribution are stored automatically and
assigned to the remote contro l key that is in use.
Four-zone automatic climate control: Th e cli­
mate control settings are automatically stored
and assigned to the remote contro l 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 condensa­
tion .
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­ tem in freezing weather until you have warmed the windshield first, using the heat­
ing and vent ilation system. The washer so lu­
tion may freeze on the w indshield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repa irs to the Aud i air cond itioner require
special technical knowledge and special
tools. Contact an authorized Audi dea ler for
assistance.
@ For the sake of the environment
By reduc ing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
windshield) free from ice, snow and debris
in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster off temporarily . These systems are availab le
