2014 AUDI A8 engine oil

(D Tips
The oil level indicator in the MMI Display is
only an information d isp lay. If the oil leve l
is low, a minimum oi l warning appears in
the instrument cluster. Add oil
r::;, page 23 7 . If the hood has been opened,
the cu rre nt oil level is shown in the instru­
ment cluster the next time the ign ition is
sw itched on.
Checking the engine oil level
Ap plies to vehicles: with oil dipstick
Fig. 202 Oil dips tick: marking fields
Before you check anything in the engine com­
partment,
alway s read an he ed all WARN­
INGS r=;,page 231.
Determining th e oil le ve l
.. Park your vehicle on a level surface.
.. Let the engine run in idle briefly while it is at
operating temperature and then shut the
engine off .
.. Wait approximately two minutes .
.. Remove the oil dips tick. W ipe off the oil dip­
stick with a clean cloth and insert it all the
way in again.
.. Remove the dipstick again and then read the
oil level

Depend ing on the way the vehicle is dr iven
and the ope rat ing cond itions, oi l consumption
can be up to
1/2 quart pe r 600 miles (0.5 liter
per
1 ,000 km) . Consumption may be higher
within the first
3,000 miles (5,000 km). Be­
cause of this, the engine oil leve l must be
checked regularly.
It would be best to check
each time you refuel your vehicle and before
long drives .

A WARNING
-
-Wh ile topping off, the o il must not come
in contact with hot engine parts -fire
hazard!
II-

238 Check ing and filling
- The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running - fire hazard!
- If your skin has come in contact w ith the
engine oil, you must subsequently
cleanse it thoroughly .
(D Note
-Check the oil level. If the message
Pl ea se r educe oil le vel appears, contact
your authorized Audi dea ler or other
qualified workshop to have excess o il ex­
tracted if necessary .
-Aud i do es not recommend the use of o il
addit ive s. They ma y damag e the engin e
and ad versely affect yo ur New Vehicle
Warrant y.
@, For the sake of the environment
- Under no circumstances can the oil come
in contact w it h the sewage network or
the soil.
- Observe and follow lega l regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com ­
partment,
al ways read and h eed all WARN ­
INGS c::> &. in Working in the engine compart­
ment on page 231.
The engine oil must be changed according to
the intervals spec ified in your Warra nty
&
Maintenance book let . This is very important
because the lubricating prope rties of oil di­
minish gradua lly dur ing normal veh icle use .
Under some c ircumstances the eng ine o il
should be changed more frequently . Change
oil more often if you drive most ly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions , or have your vehicle where tempera -tu res remain below freezing for extended pe­
riods.
Detergent additives in the oil will make fresh
o il look dar k after the engine has been run­
ning for a sho rt time. This is normal and is not
a reason to change the oil more oft en than
recommended.
Because of the problem of proper disposal,
along with the specia l tools and necessary ex­
pertise required, we strongly recommend that
you have your oil changed by an authorized
Aud i deale r or a qualified service station.
If yo u choo se to chan ge your o il yours elf ,
please note the fo llowing important informa ­
t ion:
A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil dra in p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the ground to help prevent hot oil from run­
n ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of o il in
your engine .
- Engine oil is poisonous . Keep it well out
of the rea ch of children.
- Continuous contact with used eng ine o il
is harmful to your sk in . Always protect
your skin by washing oil
off tho roughly
wit h soap and wate r.
(D Note
Neve r mix oil additives with you r engine
oi l. These additives can damage your en­
gine and adversely affect your Audi Limit­
ed New Veh icle War ranty.

@ 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 239
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 231.
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 Gl3 for your vehicle .
This coolant additive is availab le at au­
thor ized Audi dealers . O ther types of
a ntifreeze can s ignifica ntly reduc e cor­
rosion prote ction. The result ing cor ro­
sion can cau se a loss o f coolan t and se­
rio us engine d amage .
- 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
your cooling system and co uld resu lt in

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 204 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 231 .
Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the engine coolant leve l from the cool­
ant expansion tank
o fig. 204, o page 233.
With a cold engine, the coolant level should
be betwee n the "min" and "max" markings.
When the engine is warm, the level may be slightly above the "max" marking .
The location of the coolant expans ion tank
can be seen in the engine compartment illus ­
tration
o page 233.
To obtain an accurate reading, the engine
must be switched
off.
The expansion 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 16 wi ll
illuminate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant l oss
Coolant loss may indicate a le ak in the cooling
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 coo lant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult 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
fect the funct io n and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant .
Before you check anyth ing in the eng ine com­
partment,
alw ay s re ad and h eed all WARN­
IN GS o .A in Working in the engine compart­
ment on page 231.
• Tu rnoff the engi ne.
• Let the eng ine cool down.

242 Checking and filling
-The auxiliary e lectric fan is temperature
controlled and can switch on suddenly
even when the engine is not runn ing.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.
Fig . 205 E ng ine co mpartment: cove r on the brake fluid
r eservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS 9 &_ in Working in the engine compart­
m ent on page 231.
.. Read the brake fluid level from the brake
fluid reservoir
9 fig . 205, q page 233. The
brake fluid leve l must be between the "MIN"
and "MAX" markings.
The location of the brake fl uid reservoir can be
seen in the engine compartment illustrat ion
9 page233.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/ind i­
cator light
1111 (U.S. models)/ . (Canadian
models) will come on
q page 14. Do not con­
tinue to operate the vehicle . T he complete
brake system should be thoroughly checked by an authorized Audi dealer or other quali­
fied fac ility and the cause corrected.
If th e
brake flu id level is too low, the brake wa rning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by on 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
a fter a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt 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 .
.&, WARNING
-Brake fluid is poisonous. It must be stor­
ed only in the closed origina l container
out of the reach of children!
- Brake failure can result from old or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SAE
spec ification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
Always check with your authorized Aud i
dealer to make sure you are using the
correct brake fluid. The correct type of
brake fluid is also indicated 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
