Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts .
In order to provide effective lubrication and
cooling of interna l eng ine components, all in
te rnal combust io n engines consume a certa in
amount of oil. Oil consumpt ion va rie s from
engine to engine and may change sign ifi can tly
ove r th e life of the engine. Typically, engines
wi th a spec ified break -in pe riod (see
¢ page 196) consume more oil during the
break-in pe riod than they cons ume after oi l
consumption has stabilized.
U nder normal cond itions, the rate o f oi l con
s u mption depen ds on the q ual ity and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac
tors are the amount of oil dilut ion from water
condensa tion or fuel residue a nd the oxida
tion level of the oil. As any engine is subject to
wea r as m ileage builds up, the oil consump
t ion may incre ase over time until replacement
of wo rn components may be come necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es
tabl is h ed or spec ified. There is no alte rn ative
to regul ar and frequent che cking of the o il lev
el , see
Note.
If the yellow engine o il leve l warning sy mbo l

(D Tips
- The oil pressu re warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, chec k the oil level in
your engine at regular intervals, pref
erably each time you refuel, and always
before going on a long trip.
- If you have the imp ress ion your engine

A WARNING ,~
- When adding oil, do not let oil drip onto
hot engine components. There could be
risk of a fire.
- You must secure the cap on the oil filler
opening correctly so that oil does not
leak out onto the hot engine and exhaust
system when the engine is running, be
cause this is a fire hazard.
-Always clean skin thoroughly if it comes
into contact with engine oil.
(D Note
- The oil level must not be above the G)
range ~page 218, fig. 166, because this
can cause damage to the catalytic con
verter or the engine. Contact your au
thorized Audi dealer or qualified repair
facility to have excess oil extracted if
necessary.
- Do not mix any additional lubricants into
the engine oil. Damage cause by such ad
ditives is not covered by the warranty.
@ For the sake of the environment
- Oil should never enter the sewer system
or come into contact with the ground.
- Pay attention to legal requirements
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, always read and heed all WARN
INGS
~ page 214.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet. This is very important
because the lubricating properties of oil di
minish gradually during normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis-
Checking and Filling 219
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con
ditions, or have your vehicle where tempera
tures remain below freezing for extended pe riods.
Detergent additives in the oil will make fresh
oil look dark after the engine has been run
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended .
Because of the problem of proper disposal,
along with the special tools and necessary ex pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choose to change your oil yourself, please note the following important informa
tion:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch .
- When removing the oil drain plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil off thoroughly
with soap and water.

@) For the sake of the environment
- Before changing your oi l, f irst 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 .
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 ui res little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -based coolant addi -
tive G l3 antifreeze with anticorrosion addi
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces
sary frost pro tection and protec ts metal com
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil
i ng po int of the coo lant .
Do not red uce the concentr ation of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficie n
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35°C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .
.&, WARNING "---
Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS ~
page 214.
0 Note
- Before wi nter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
ma te conditions. This is especi ally impo r
tan t if you live in a reg ion where the win

Other types of antifreeze can sign ifi
ca ntly reduce corrosion p rotection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal

Che cking and Fillin g 221
A WARNING
The cooling system is pressurized and can
become very hot. To reduce the r isk of
burns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine hot . The re is a risk of
burns .
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tank cap with a large, th ick
cloth .
- Tu rn the coolant tank cap counterclock
wise slowly and keep light pressure on
the cap.
- To reduce the risk of burns, do not allow
any antifreeze o r coolant to drip onto the
exhaust system or hot engin e compo
nents . The ethy lene g lycol in eng ine
coo lant can catch fire under certai n cir
cumstances.
- The coolan t addi tive and the coolant can
be dangerous to your health. For this
reason, keep the coo lant in the origina l
container away from ch ildren. There is a
risk of poisoning.
- When working in the engine compart
ment, remember that the radiator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
personal injury.
(D Note
Do not add coolant if the expans ion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue dr iving. See an author ized
Audi dealer or authorized Audi Service Fa
c ility for ass istance.
Radiator fan
The radiator fan switches on automatically by
itself.
An auxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
