Warm and cold
Climate control system
Description
Different systems cou ld be installed.
- manual climate control system* or
- automatic climate control system*
The
clim ate co ntrol system * cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and panorama sunroof* are closed. If
there is a build-up of heat inside the vehicle,
ventilation can help to speed up the cooling process . For this reason, the windows and
panorama sunroof can be opened from the
outside
r::} page 3 9, Convenience opening/
closing.
The pollutant filter removes pollutants such
as dust and pollen from the air .
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe dr iv ing it is very important that
all windows be free of ice, snow and con­
densation.
- Completely fami liarize yourself with the
proper use and function of the heating
and ventilation system and especia lly
how to defog and defrost the windows .
- Never use the windshie ld w iper/w asher
system in freezing weather until you
have warmed the windshield first, using
the heat ing and ventilation system . The washer sol
ution may freeze on the wind­
shie ld and reduce visib ility.
@ 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 q ualified dealership.
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Aud i
dealer for ass istance.
@ For the sake of the environment
By reducing the amount of f uel you use,
you also reduce the amount of pollutants
emitted into the air.
(1) Tips
- To prevent interference with the heat ing
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can drip a nd form a puddle of wa ter un­
der the vehicle . This is normal and does
not mean t here is a leak.
- The energy ma nagement system may
switch the seat h eating* or rear window
defroster off temporar ily. These systems
are available again as soon as the energy
balance has been resto red.
- Air escapes through vents under the rear
w indow. When plac ing items of cloth ing
on the luggage compartmen t cover, en ­
sure t hat the openings are not covered .

66 Warm and cold
Foot vents are located under the front seats
to heat the rear of the vehicle.
l= I Switching recirculation mode on and
off
I n recirculation mode, the air inside the vehi­
cle is circu lated and filtered. This prevents the
unfiltered air outside the vehicle from enter­
ing the vehicle interior. We recommend
switching recirculation mode on when driving

smoothly and reliably. Choosing the right oil
and changing oil within the time and mileage intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a special quality standard for engine oil that
will help assure that your vehicle's engine will get the lubrication it needs for proper opera­
tion .
Modern engine lubrication has taken a quan ­
tum leap in the last few years. Many synthetic
oils available today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils , making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleum­ based engine oil , the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine
running smoothly and help prevent the for­
mation of harmful deposits, sometimes called
"sludge", that over time can lead to expensive
repairs .
At the time of printing, engine oils available in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils. This does not mean, however, that every synthetic engine oil will
meet Audi oil standard VW 502 00 . So always
be sure that you use an approved oil.
To help prevent the formation of harmful de­ posi ts use only oil with the following specifi­
cations printed on the oil container:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion singly or in combination with other desig­
nations and oil quality standards.
Viscosity
Engine oils are graded according to their vis­
cosity . The proper viscosity grade oil for your
engine depends on climactic or seasonal con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across all tem­
perature ranges for normal driving conditions.
Checking and Filling 213
However, if engine oil viscosity grade SAE
5W40 is not available , you can also use viscos­
ity grade SAE 5W -30 or SAE OW-40 as long as
it meets Audi oil quality standard VW 502 00
specifications.
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart
(liter) of oil that expressly conforms to the
VW 502 00 spec ificat ion, in case you have to
top off the oil while on the road .
Only if the level of the oil is at or below the
minimum mark -and no oil that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top off
with a high quality engine oil , preferably syn ­
thetic-based, that meets ACEA A3 or API SM specifications, but even then, only in viscosity
grades SAE 5W-40 , SAE SW-30, or SAE
OW-40. However, during the entire time be­
tween oil change intervals, never top off with
more than a total of 0.5 qt/liter engine oil
that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822 -2834
or v isit our web site at www.audiusa .com or
www .audicanada .ca. Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your veh icle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter-
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when .,..

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
