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 i nternal engine components, a ll in­
ternal comb ustion eng ines consume a certa in amount of oil. Oil consumpt
ion varies from
engine to engine and may change significant ly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
<=> page 196) consume more oil during the
break -in pe riod than they consume after o il
co nsump tion has stabilized.
Under normal cond itions, the rate of oil con ­
sumption depends on the q ua lity and viscos ity
of the oil, the RPM (revolut ions per minute) at
wh ich the engine is operated, t he ambie nt
temperature and road conditions . Fur ther fac­
tors a re the amount of oil dilut ion from wa ter
condensation or f ue l resid ue and the oxid a­
t ion level of the o il. As any engine is subjec t to
wear as m ileage builds up, t he oil consump­
tion may increase over time until replacement of wo rn components may become necessary.
W it h a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alte rnative
to regu lar and frequent check ing of the o il lev­
el, see
Note .
If
the yellow engine oil level warning symbo l
in the instrument cluster
I!!! lights up, you
shou ld check the oil leve l as soon as possib le
<=> page 215. Top off the oil at your earliest
convenience
<=> page 215.

-If you have the impression your engine
consumes excessive amounts of oi l, we
recommend that yo u consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time . Your Audi dealer has in­

Changing the engine oil
We recommend that hove your oil changed by
on authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lw ays r ead and heed all WARN­
ING S
~.&. in Working in the engine comport­
ment on page 211.
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 dur ing normal vehicle use .
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
d itions, or have your veh icle where tempera­
tures remain below freezing for extended pe­ riods.
Detergent additives in the oil w ill make fresh
oil look dark after the eng ine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil mo re often tha n
recommended.
Because of the problem of proper disposal,
a long w ith the special tools and necessary ex­
pe rtise required, we strong ly recommend that
you have yo ur o il changed by an authori zed
Audi de ale r or a qualified service station.
If yo u choo se to chan ge your oil 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 engine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en-
g ine 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 your 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 wel l out
of the reach 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 changi ng your oil, first make sure
you know where you can prope rly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open st reams o r down
sewage drains.
- Re cycle used engine oil by taking it to a
used eng ine oil collect io n fac ility in you r
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 sealed and generally re­
qu ires little attention .
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of specially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with anticorros ion addi­
tives (50% for USA models; 60% for Canadian models) . This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's cooling system from
corrosion and scaling.
It also raises the boil ­
ing point of the coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and eng ine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- -40 ° F ( - 40 °C) Canada.
I f you must add coo lant, use a mixture of wa­
ter and coolant addit ive. Mixing the coolant
additive with distilled water is recommended.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~.&.
in Working in the engine
compartment on page 211.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
Checkin g and fillin g 217
your vehicle is sufficient to meet the cli ­
mate conditions. This is especia lly impor­
tant if you live in a region where the win­
ter is extremely co ld. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
avai lable at authorized Audi dealers .
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

the leve l may be slightly above the "max"
mark ing .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
9 page 213.
To obtain an accurate reading, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning l ight in the Auto-Check System
9 page 15 w ill
illum inate unti l 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 le ak in the cooling
system . In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
s ealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and can get very hot. Reduce the risk of scald­
ing from hot coolant by followi ng these
steps .
- Turn off the engine and allow it to coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefu lly in
a counter-clockwise direction w hile ap­
plying light, downward pressure on the
top of the cap . -
To avoid being burned, do not spi ll anti­
freeze or coolant on the exha ust system
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator repair fluid may adverse ly af­
fect the funct ion and pe rformance of you r
cooling system and could result in damage
