Warm and cold
Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature.
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y re cognition
A pp lies to: ve hicles w ith de luxe au toma tic clima te co ntrol
The blower sett ing and air distribution are stored
automatically and ass igned to the remote control
key that you are using.
A pp lies to: ve hicles w ith 4 -zo ne del uxe automatic c limate
co ntrol
The climate control set tings are automatically
stored and assigned to the remote control key
that is in use.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with
the correct use and function of the climate contro l system, especially with the defrost­
ing and defogg ing function.
58
- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­ mate control system . The washer fluid could
freeze on the w indsh ield and impair v isib il i­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system
off to
prevent further damage and have it checked
by an authorized Aud i dea ler or authorized
Audi Serv ice Facility.
- Repa irs to t he Aud i climate control system
require special techn ical know ledge and
special tools. See an aut ho rized Aud i dea le r
or authorized Aud i Serv ice Fac ility .
@) For the sake of the environment
To save fue l, turn off cooling mode by press­
i ng the
IA/Cl button. This will a lso reduce
emissions.
(D Tips
- T o prevent i nterference with t he heat ing
and cooli ng outpu t and to p revent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- C ondensation from the coo ling system can
drip and form a pudd le o f water under the
vehicle . This is norma l and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h
off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.
