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 w indows and
sunroof* are closed. If there is a build-up of heat
inside the vehicle, ventilation can help to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
Appl ies to: ve hicles with de luxe a utoma tic clima te co ntro l
The blower setting and air distribution are stored
automatically and assigned to the remote control
key that you are using.
Appl ies to: ve hicles with 4 -zo ne del uxe automat ic cl imate
co ntrol
The climate control settings 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 defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
Warm and cold
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­ ty .
(D Note
-If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Aud i Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
or authorized Audi Service Facility.
@ For the sake of the environment
-To save fuel, turn off cooling mode by press­
ing the
IAJCI button . This will also reduce
em iss ions.
- In vehicles w ith a diesel engine, you can
switch the auto supplementary heater off in
the Infotai nment system.
(D Tips
- To prevent interference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
- The energy management system may tem­
porarily switch off certain functions, such as
the seat heating* or rear window defogger .
These systems are avai lable aga in as soon
as the energy supply has been restored.

-Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not switch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these conditions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as we ll as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
® For the sake of the environment
Even when the Emission Control System is op ­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states. This depends on the su lfur
content of the fuel being used. Using a differ­
ent brand of fue l may help, or filling the tank
w ith lead-free super grade gasoline .
Diesel particulate filter
Applies to: veh icles with diesel engine
The diesel particulate filter filters nearly all of
the soot particles out of the exhaust. The filter
cleans itself automatically under normal driving
conditions . If the filter cannot clean itself (for ex­
ample , because you are only driving short distan­
ces), the fi lter becomes clogged with soot and

Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The service interval display in the instrumen t
cluster of your vehicle will inform you when it is
time for an oi l change. We recommend that you
have your oi l changed by an authorized Audi Serv­
ice Advisor.
If you must add oil between oil changes, use an

- The engine oi l consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depending on driving style and operating
conditions. In RS models, the oil consump­
tion may be up to 1 qt/600 mi (0.8 L/ 1,000 km). Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
cause of this, the engine oil level must be
checked regular ly.
It would be best to check
each time you ref uel your veh icle and befo re
l ong d rives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified service sta­
tion .
Before you check a nyth ing in the eng ine compart­
ment,
alway s re ad and heed all WARNING S 9 &.
in Working in the engine comportment on
page 199.
The engine oil must be changed according to the
intervals specified in you r Warranty
& Mainte­
n ance booklet. This is very impo rtant because the
l ub ricating properties of oil diminish gradually
during normal vehicle use.
Unde r some ci rcumstances the e ngine o il should
be cha nged more frequently . Change oil mo re of­
ten if yo u drive mostly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
q ui red, we strongly recommend that you have
your oil changed by an authorized
A ud i dealer or
a qualified service station.
If you choose to chang e your o il your self, please
note the following important information:

- To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oi l in you r engine .
- Engine oil is poisonous. Keep it we ll out of
the reach of children.
- Continuous contact with used engine o il is
harmf ul to your skin. Always protect your
skin by washing oil off thoroughly with soap
and wate r.
