Pollutant filt er
The pollutant filter (particle filter) ensures
that contaminants in the outside air (such as
d ust or pollen) are greatly reduced or stop­
ped. The air is also filtered in recircu lation
mode.
The po llutant filter element must be changed
according to the intervals specified in the
maintenance schedule so that the air condi­
tioning system's performance is not adversely
affected .
If the filter's effectiveness is weakened by
driving the vehicle in areas with heavily pollut­
ed outside air, the filter element should also
be changed in between the listed services.
A WARNING
For safety reasons, it is important that all
w indows are free of ice, snow, and conden­
sation. Only then is good visib ility ensured.
Please fam iliari ze yourse lf with the co rrec t
operation of the air conditioning and how
to de humidify/defrost the windows .
([) Note
-If you suspect that the clima te controls
have been damaged, swi tch the system off to avoid damaging it, and have it in­
spected by an authorized Audi dea
ler .
- Audi climate control system repairs re­
quire special expertise and the proper

(D Tips
- To avoid adversely affecting heating and
cooling performance and to prevent con­
densation on the windows, the air intake
in front of the windshield must be free of
ice, snow, and leaves.
- The a ir coming from the vents and circu­
lat ing through the entire interior is ex­
tracted through the out let slots in the
side pane ls in the luggage compartment .
Make sure that the outlet slots are not
covered by clothing, etc.
- Climate contro l works most effectively if
the windows are closed. However, if the
inter io r of a par ked veh icle is ext reme ly
hot from the sun's rays, briefly opening
the windows can speed up the cooling process .

Also , sa fe ty a nd en vir onm ent al con­
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans­
miss ion parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­

Improper maintenance, adjustments and re­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­

ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop.
