air condition AUDI A6 2014 User Guide

-Never place or attach accessories or o th ­
er objects (such as cup hol ders, tele­
phone brackets, large, heavy or bulky ob­
jects) on the doors, over or near the area
marked ''AIRBAG" on the steering wheel,
instrument panel, seat backrests or be­
tween those a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate .
- Never recline the front passe nger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­ pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be
off, or co uld
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout the object on the seat. A

A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of as thma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those wi th asthma o r other respiratory
conditions s hou ld get fresh air r ight
away by get ting o ut o f the veh icle or
open ing win dows or do ors.
- If you are in a collision in which airbags
deploy, was h your ha nds and fa ce with
mild soap and wate r be fore eating.
- Be ca reful not to get the dust in to your
eyes, o r into any c uts or sc ratches.
- If the resid ue should get into your eyes,
f lus h t hem w ith wa te r.
Monitoring the
Advanced Airbag System

light.
The Advanced A irbag System ( includ ing the
electron ic co ntro l unit, sensor circu its and sys­
tem wir ing) is monitored con tinuously to
make sure that it is functio ning properly
whenever the ignition is on. Each time you
switch on the ignition, the airbag monitor ing
indicator light

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a
collision .
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
~ page 139, What happens to occupants not
wearing safety belts? .
But unlike adults and
teenagers, their muscles and bones are not
fu lly developed. In many respects children are
at greater risk of serious injury in crashes than
adu lts.
Because children's bod ies are not fully deve l­
oped, they require restraint systems especial­ ly designed for their size, weight, and body
structure. Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re­
straint systems for infants and small children .
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant w ill be more than 20 t imes the
weight of the child . This means the weight of
the child would suddenly be more than
260 pounds (120 kg). Under these conditions,
on ly an appropriate chi ld restraint properly
used can reduce the risk of ser ious injury .
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp­
erly, they can increase the risk of serious in ­
jury in an accident.
Consult the child safety seat manufacturer's
instructions in order to be sure the seat is
right for your chi ld's size ~
page 177, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the important information and WARNINGS
about ch ild safety, Advanced A irbags, and the
installation of child restraints in this chapter.
There is a lot you need to know about the Ad­
vanced Airbags in your vehicle and how they work when infants and children in child re-
Child Sa fet y 173
straints are on the front passenger seat . Be­
cause of the large amount of important infor­
mation, we cannot repeat it a ll here . We urge
you to read the detailed information in this owner's manual about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­
ing children on the front passenger seat .
Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of your passengers, especially in­
fants and small chi ldren .
.A, WARNING
-Accident statistics have shown that chil ­
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un­ der in the rear.
- All vehicle occupants and especially chil­
dren must be restrained properly when­
ever riding in a vehicle . An unrestrained
or improperly restrained chi ld could be
injured by str ikin g the interior or by be­
ing ejected from the vehicle during a
sudden maneuver or impact. An un re ­
strained or improper ly restrained chi ld is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable chi ld restraint properly instal­
led and used at one of the rear seating
positions provides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING
Children on the front seat of any car even
with Advanced Airbags can be ser iously in­
jured or even killed when an a irbag in­
flates. A child in a rearward-fac ing ch ild
safety seat installed on the front passen­
ger seat will be ser iously injured and can
be killed if the front airbag inflates .
- The inflating airbag will h it the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, or door.

198 Intelligent technology
Clean off accumulated salt coating from
brake discs and pads with a few caref ul
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed . Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­ creased stopp ing distan ce. Avoid driv ing
the vehicle a nd have it towed to t he near­
est Aud i dea ler o r qualified workshop.
- Never let the vehicle rol l to a stop w ith
the engine shu t off.
- If the brake booster is not working, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.

Winter tires
When dr iving in the win ter, yo ur vehicle wi th
all-wheel drive has an advantage, eve n with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all fou r
w heel s.

Tire chain s
Where tire chains are mandatory on certain roads, this norma lly also app lies to ve hicles
with all-wheel drive¢
page 256, Snow
chains .
Replacing wheel s/tire s
Vehicles with a ll-wheel drive must always
have tires of the same size. A lso avoid tires
with different tread depths . For detai ls see

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

Modern eng ine 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 (vehicles with gasoline engine) or
VW 507 00 (veh icles with diesel engine) to
he lp keep your vehicle's eng ine running
smoothly and help prevent the fo rmation of
harmf ul depos its, sometimes ca lled "sludge,"
that over time can lead to expensive repairs.
At the time of pr inting, engine o ils availab le in
the U.S. and Canada tha t meet the exacting
specifications of A udi oil standard VW 502 00
(vehicles with gaso line engine) or VW 50 7 00
(vehicles with diesel engine) are synthetic en­
gine oils . This does not mean, however, that
every synthetic engine oil will meet Aud i oil
standard VW 502 00 (vehicles with gasoline
engine) or VW 507 00 (vehicles w ith diese l
engine). So always be sure that you use an ap­
proved oil.
To help prevent the formation of harmful de­
posits use only oil with the follow ing spec ifi­
cations printed on t he oil container:
- Aud i oil standard VW 502 00 (gasoline en ­
gine )
- Aud i oil standard VW 50 7 00 (d iesel en -
gine )
Oil conta iner labe ls may carry the specif ica ­
tion singly or in comb ination with other desig­
nations and oil qua lity standards.
Vi scosi ty
Eng ine oils are graded acco rding to their v is­
cosity. The prope r viscosity grade oil for your
engine depends on cl imac tic or seasonal con­
d itions where you dr ive. You can use oi l with a
viscosity grade of SAE SW40 across all tem ­
pe rat ure ranges for normal d riving conditions .
H oweve r, if eng ine oi l viscosity grade
SAE SW40 is not ava ilable, you can a lso use
Checkin g and fillin g 22 7
viscosity grade SAE 5W -30 or SAE OW-40 as
long as it meets Audi oil q uality standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles w ith diese l eng ine) spec­
ifications.
Because engine oil that meets the Audi oi l
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 (veh icles with gasoline engine) or
VW 507 00 (vehicles w ith d iese l eng ine) spec­
ification, in case you have to top off the oil
wh ile on the road.
App lie s to vehicle s with gasoline engin e on­
l y:
Only if the level of the o il is at or below the
minimum ma rk on the o il dipstick -and no oi l
that expressly conforms to Audi o il st andard
VW 502 00 spec ificat ions is available - may
you top off with a high quality engine o il, pre f­
erably synthetic -based, that meets ACEA A3
or API SM specificat ions, but even then, only
in v iscosity grades SAE SW-40, SAE SW-30, or
SAE OW-40. However, during the entire time
between oil change intervals, never top off
with more than a total of 0 .5 qt/liter engine
o il that does not conform to Audi o il specifica­
tion VW 502 00.
App lie s to vehicles with die sel engin e only:
Only if the level of the o il is at or below the
min imum ma rk on the o il dipstick - and no oi l
t h at exp ressly conforms to Audi o il standard
VW 507 00 spec ificat ions is available - may
you top off with a high quali ty engine o il, that
meets ACEA C3 or API CF specifications, but
even t hen, only in viscosity grades SAE
SW-40, SAE 5W-30, or SAE OW-40. However,
during the entire time between oil change in­
terva ls, never top off with more than a total
of 0. 5 qt/liter engine oil that does not con-

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

@ For the sake of the environment
-Before changing your oil, first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­

- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station .
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
q uir es lit tle atten tion .
The cooling system has been filled at the fac ­
tory with a pe rmanent coo lant which does not
need to be c hanged. The coolant consists of a
mixture o f spec ial ly conditioned water and the
manuf acturer 's glyco l-based cool ant ad di-
tiv e G13 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els) . This mixture both assures the neces­

ponents in the engine's coo ling system from
corrosion and scaling . It a lso raises the boil­
i ng point of the coolant .
Do not reduce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add it ive must be at
l e a st 50 % but not mor e than 60 %
to main­
tain antifreeze protection and coo ling efficien­
cy .
If the coolant frost protect io n is too low,
the coolant cou ld free ze and dam age the veh i­
cle heating and eng ine cooling system.
For yea r-round driving, antifreeze is added at
the fac to ry for tempera tures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.

high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld also be
checked each time the battery is charged

Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
