2014 AUDI A6 engine coolant

@ 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
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- 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
sary frost protection and p rotect s metal com ­
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.
Checkin g and fillin g 231
If you must add coo lant, use a mixture of wa ­
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended.
_& WARNING
Before you c heck anything in the engine
compartment, always read and heed a ll
WARNINGS
c> .& in Working in the engine
comportment on page 224.
Q) Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate condi tions. This is especi ally impor­
tan t if you live i n a region wher e th e win­
ter is ex treme ly co ld. If necessary, i n­
crease t he p ropo rtion of coo lant add itive
to 60% .
- Whe n ad ding coolant additive t o yo ur
c ooling sys tem, reme mbe r:
- We recommend using on ly coolant ad­
d itive G12++ or G13 (check the labe l)
fo r your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs .
Ot he r ty pes of antifree ze can sign ifi­
cantly reduce corros io n protection. The
r es ult ing co rrosion can ca use a loss of
coolan t and serious e ng ine damage.
- Do not add any ty pe of rad iator leak seal­
a nt to yo ur vehicle 's engine c oolant .
A dd ing radia tor repair fl uid may adverse ­
ly affect the f unction and pe rformance of

232 Check ing and filling
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 191 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com­
partment,
a lwa ys re ad and h eed a ll WA RN­
INGS o .A in Working in the engine compart­
ment on page 224 .
., Park your vehicle on a level surface.
., Switch
off the ignit io n.
., Read the eng ine coolant level from the cool ­
ant expans ion tank
o fig . 191, o page 226,
fig. 188. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant exp ans ion tank
can be seen in the engine compartment illus­
tration
o page 226.
To obtain an accurate read ing, the engine
must be switched
off.
The expans ion tank in your vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System
o page 17 will
illum inate unt il you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coolant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot . Red uce the risk of scald­
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying light, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts . Under certa in cond i­
tions, the ethylene glycol in engine cool­
ant can catch fire.
0 Note
Do not add any type of radiator leak seal­
ant to your veh icle's engine coolant . Add­
i ng radiator repa ir fluid may adverse ly af­
fe ct the funct io n and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.

Brake fluid
Checking brake fluid level
Fig. 192 Engine compartment : cove r on the brake fl uid
reservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ~ .&. in Working in the engine compart ­
ment on page 224.
.,. Read the brake fluid level from the brake
fluid reservoir~
fig. 192 , ~ page 226,
fig.
188. The brake fluid leve l must be be­
tween the "MIN" and "MAX" markings .
The location of the brake flu id reservoir can be
seen in the engine compartment illustrat ion
~ page 226.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . Th is is not cause for alarm.
I f the brake fluid level falls
considerably be­
lo w the "MIN" mark, the brake wa rning/indi­
cator light
1111 (U.S. models)/ . (Canadian
models) will come on~
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the ca use corrected. If the
brake fluid level is too low, the brake warning/
indicator light w ill illuminate . Contact an au ­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake fluid will also decrease considerably and
decrease braking pe rformance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FM VSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer . Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The correct type of
brake flui d is also ind icated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can seriously affect the effi­
c ie ncy of the brakes as well as your
safety. This could result in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

The washer fluid container is marked with the
symbol~ on its cap
¢fig . 194, ¢page 226,
fig. 188 .
.,. Before you check anyth ing in the engine
compartment,
always read and h eed all
WARNINGS ¢ A in Working in the engine
compartment on page 224 .
.,. Lift the filler cap tongue to add washer flu­
id. You can fill the container to the top .
.,. Press the cap back onto the filler neck after
fill ing the container .
You can f ind the reservoir
capa city in the table
in
¢ page 281.
C lean water sho uld be used when filling up. If
possible, use soft water to prevent sca ling on
washer jets. Always add a glass cleaner solu­
tion (with frost protection in the winter).
CJ) Note
Do not mix engine coolant antifreeze or
any other add itives to fill up the wind­
shie ld washer reservoir.
