2014 AUDI A6 air filter

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior .
It is the most effective when the windows and
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.

A WARNING
-
Reduced visibi lity is dangerous and can
cause acc idents .
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam il iarize yourse lf with the
proper use and funct ion of the heat ing
a nd ventilation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer system in freez ing weathe r unt il you
have wa rmed the windshie ld first, using
the heating and ventilation system. The
washer sol ution may freeze on the wind­
shie ld and red uce visibi lity.
CJ) Note
- If you s uspect that the air conditioner
has been damaged, switch the system
off to avoid furt her damage and have it
inspected by a qualified dea lership .
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Audi
dealer fo r ass istance.
@ For the sake of the envi ronment
By reducing the amount of f uel you use,
you also red uce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear window. When plac ing items of cloth ing
on the luggage compartment cover, en­
sure that the openings are not covered.

202 Driving and en vir onm ent
Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 215,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 229, Adding engine oil .. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exhaust tail pipes once
they have become hot. This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will al ready seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
¢page 229.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
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
vehicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter ill uminates ¢
page 22. ..,.

228 Check ing and filling
current list of oils (manufacturers , brand
names etc.) that conform to Aud i oi l standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang in g th e en gin e oil
The engine oil and o il filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls spec ified in your vehicle's War­
ranty
& Maintenance booklet . Do not exceed
these intervals - harmful deposits from old
engine o il can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inte r­
va ls is so very important because the lubricat­
ing properties of oi l decrease grad ually during
norma l vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor .
Under some circumstances the engine o il
should even be changed more frequently .
Change oil more often if you drive mostly
short d istances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing point fo r
l ong periods.
Detergent add it ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is no rma l and is not
a reason to change the o il more often than
recommended.
Dama ge or ma lfun cti ons du e to la ck of
maint enan ce
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles wi th gaso lin e engine) or
VW 507 00 (veh icles with diese l engine) . Yo ur
Limited New Vehicle Warranty does not cover
damage or ma lf u nctions due to failure to fol­
low recommended maintenance and use re­
qu irements as set forth in the A udi Owner's
Manual and War ranty
& Maintenance book let.
Your dea ler will have to deny warranty cover­
age unless you present to the dealer proof in the form o
f Service or Repair Orders that all
scheduled maintenance was performed in a
t imely manner.
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil
of its moving ports.
In order to provide effective lubrication and
cooling of interna l engine components, all in­
ternal combust ion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically , engines
with a spec ified break- in period (see
¢ page 201) consume more oil during the
break -in pe riod t han they consume afte r o il
consumption has stabilized.
Under normal cond it ions, the rate of oil con­
sumption depends on the q ua lity and viscos ity
of the oil , the RPM (revol utio ns per minute) at
which the engine is opera ted, the ambient
temperature and road conditions . Furt her fac­
tors are the amount of oil dilution from water
condensation or fue l residue and the oxida ­
tion level of the oil. As any engine is subject to
wear as m ileage builds up, the oil consump­
t ion may increase over time until replacement
of worn components may become necessary .
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es­
tablished or spec ified . There is no alternative
to regular and frequent checking of the o il lev­
el, see
Not e.
If the yellow engine oil level warning symbol
in the instrument clus ter
II lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 229 . Top off the oil at your earl iest
convenience
