Pollutant filter
The pollutant filter (particle filter) ensures
that contaminants in the outs ide a ir (such as
dust or pollen) are greatly reduced or stop­ ped . T he air is also f iltered in recircu lation
mode .
The pollutant 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 effect iveness is weakened by
d riving the vehicle in areas with heavily pollut ­
ed outside air, the filt er element should also
be cha nged in between the listed services.
.&, WARNING

w indows are free o f ice, snow, and conden­
sa tion . Only then is good visib ility ensured .
Please familiarize yourse lf wit h the co rrect
operation of the air conditioning and how

steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Als o, sa fe ty a nd en vir onm ent al con­
cerns p lace 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 dev ices and oth­
er equipment available to specially trained
workshop personnel in order to assure proper pe rformance, reliab ility and safety of the vehi­
cle and its many systems .
Improper maintenance, adjustments and re­ pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore , proof of servic ing in accord­
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 .
We strong ly urge you to give yo ur a utho rized
Aud i dealer the opportunity to perfo rm all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, original parts
and trained spec ialists to keep your vehicle
running properly .

_& WARNING
- Ser ious personal injury may occur as a re­
sult of improperly performed mainte­
nance, adjustments or repa irs .
- Always be extremely careful when work­
ing on the vehicle . Always follow com­
monly accepted safety pract ices and gen­
eral common sense. Never r is k personal
inju ry.
- Do not attempt any of the maintenance ,
checks or repairs descr ibed on the fol­
lowing pages if you are not fu lly fam iliar
with these or other procedures with re ­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your author ized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the radiator fan. It is temperature controlled and can sw itch on suddenly -
even when the engine is off and the igni­
tion key has been removed. The rad iator
fan switches on automa tical ly when the
coo lant reaches a certain temperature
and will continue to run until the coo lant
temperature drops .
- Always remove the ign ition key before
anyone gets under the vehicle.
- Always support your veh icle with safety
stands if it is necessary to work under­
neath the vehicle. The jack supplied with
the vehicle is not adequate for this pur­ pose and cou ld collapse causing serious
personal injury.
- If you must work underneath the vehicle with the wheels on the ground, always
make sure the vehicle is on leve l ground,
that the wheels a re a lways secure ly
b locked and that the engine cannot be
started.
