~. Diesel particulate filter clogged
Appl ies to vehicles: with d iesel e ngine and diese l pa rticu ­
late fi lte r
II Particulate filter: System fault See own­
er's manual
When the II symbol illum inates, you can al­
ter your driving style to assist the filter self­
cleaning process. Drive for approximately 15
minutes with the selector lever in the 5 posi­
tion at a minimum speed of 37 mph (60 km/
h) and an engine speed of approximately
2,000 RPM. The temperature increase that
will resu lt from this can burn off the soot in
the filter . The symbol will switch off when the
cleaning is successful. After a successful
cleaning , there is no need to bring the car to
an author ized dealer or qualified workshop
because this is part of normal vehicle ope ra­
tion .
If the symbol
II does not switch off, see your
author ized dealer or other qualif ied workshop
to have the problem corrected.

Cooler
Introduction
Applies to vehicles: wi th coo ler
Please clean the cooler before using it for the
first time ¢
table on page 216.
You can only switch on the cooler if
- the temperature in the luggage compart­
ment is below 131 °F (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds
131 °F (55 °C). Once the temperature falls
below 131 °F (55 °C) again, the cooler
switches on again automatically.
- the battery is adequately charged. The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the battery from discharg­ ing. The cooler switches back on again auto­
matically when the battery voltage increases
again (e .g. after starting the engine).
The cooler cools to 42.8 °F
(+ 6 °C) and the
freezer cools to 21.2 °F (-6 °C) in optimum
cooling conditions. The cooling performance
is affected by the temperature in the luggage
compartment . The temperature inside the
cooler will be higher if the luggage compart-
ment is hot. .,.

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 the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing 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.
Condensation 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 pol lutant filter removes pollutants such
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.
I f you drive your vehicle in an a rea with high
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The climate control settings are a utomat 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 funct ion of the heat ing
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 sh ie 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 temporari Ly . These systems
are available again as soon as the energy
balance has been restored.
