VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hang ing th e engin e oil
The engine oil and oi l filter must be changed
according to the m ileage (kilomete rs) and
time inte rva ls specified in yo ur vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive eng ine repairs.
Changing the o il at the recommended inter ­
va ls is so very important because the lubricat ­
ing properties of oi l decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author­
ized Audi Service Advisor.
Under some circumstances the engine oi l
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your veh icle where
temperatures stay below freezing point for
l ong periods.
Detergent addit ives in the o il 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 o il mo re often than
r ecommended.
D amage or ma lf u nction s du e to lac k of
ma int enance
It is essential that you change your oil at the
recommended interva ls using only engine oil
that complies with Audi oil standard
VW 502 00 (veh icles with gasolin e engine) or
VW 507 00 (veh icles with diese l engi ne). Yo ur
L im ited New Vehicle Warra nty does not cover
damage or ma lfunctions due to failure to fol­
l ow recommended maintenance and use re­
quirements as set forth in the A udi Owner's
Manual and Warranty
& Maintenance book let.

· 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 prov ide effective lubrication and
cooling o f inte rna l engine components, all in ­
ternal combustion 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
Q page 169) consume more oil during the
break-in pe riod than they consume after o il
consump tion has stabilized.
Under normal cond itions, the rate of oi l con­
sumption depends on the quality and viscos ity
of the oil, the RPM (revolut ions per minute) at
which the engine is operated, the ambient
temperature a nd road conditions. Further fac ­
tors are the amount of oil dilut ion from wa ter
condensation or fue l residue and the oxida ­
tion level of the oi l. As any engine is subject to
wear as mi leage builds up, the oil consump­
tion 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 consumption can be es­
tablished or spec ified. There is no alternative
to regular and frequent check ing of the oil lev­
el, see
Not e.
If the yellow engine oil level warning symbo l
in the instrument cluster
Ill! lights up, you
shou ld check the oil leve l as soon as possib le
with the oil dipstick q page 200 . Top off the
o il at your earliest conven ience

@ Tips
- The oil pressure warning display. i s
not an indicator of the oil level. Do not
r ely on it. Instead , check the oil level in
your engine at regular intervals, pref ­
erably each t ime you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amo unts of oi l, we
r ecommend that yo u consult your au­
thorized Aud i dea ler to have the caus e of

an authorized Audi dealer or a qualified serv­
ice station .
Before you check anyth ing in the eng ine com­
partment,
alw ays read and h eed all WARN­
INGS ¢
A in Working in the engine compart­
ment on page 194 .
The engine oil mus t be changed according to
the intervals spec ified in your Warranty
&
Maintenance booklet. This is very important
because the lubricat ing properties of o il di­
min ish g radually du ring normal vehicle use .
Under some c ircumstances the engine oil
should be changed more frequent ly . Change
o il more ofte n if you drive mostly short d is­
tan ces, opera te the veh icle in dus ty a reas or
u nder p redominant ly stop -and-go traffic con­
ditions, or have you r vehicle where tempera ­
tures remain below freezing for extended pe­
riods .
Dete rgent additives in the oil will make fres h
o il look dar k after t he engine has been run ­
ning for a sho rt time. T his is normal a nd is not
a reason to change the oil more often t han
recommended.
Because of the prob lem of p roper disposal,
along with the specia l tools and necessary ex­
pertise req uired, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choo se to change your oil your self ,
please note the fo llowing important informa ­
tion:
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.

202 Checking and filling
-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.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adversely affect your Audi New
Vehicle Limited Warranty.
@) For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose
of the used oil.
-Always dispose of used engine oil proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.

diesel engine when adding or changing
engine oil
App lies to vehicles: with diesel engine
On vehicles with a diesel engine always use
engine oil that conforms to Audi oil specifica­
tion VW
507 00 when adding or changing en­
gine oil.
Vehicles with diesel engines require and
must
always
use special engine oil that conforms to
Audi oil specification
VW 507 00 .
Never use any other kind of engine oil in your
vehicle, not even to top off the oil level.
At the time of printing, we are aware that Cas­
trol ® produces engine oil that conforms to Au­
di oil specification VW 507 00. This oil may
not yet be available throughout North Ameri­
ca. Other oil manufacturers may offer engine

- Not all commercially available oils con ­
form to this very rigid Audi oil quality
standard even though they may be syn­
thetic-based and have the same viscosi­
ty.
Engine cooling system
Coolant
T he 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
quires 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 water and the manufacturer's gly­
col-based coolant additive Gl2++ antifree ze
with anticorrosion additives (50% for USA models; 60% for Canadian models). This mix ­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling.
It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
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 antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
Checking and filling 203
For year-round driving, antifreeze is added at
the factory for temperatures down to:
--31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
You can mix the Gl2 ++ coolan t additive with
other additives Gl2 + or Gl2. Always check
with your authorized Audi dealer .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~
& in Working in the engine
comportment on page 194.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the
win­
ter is extremely cold. 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 G 12++ (check the label) for your
vehicle. This coolant additive is availa­
ble at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant 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 Vehicle
Limited Warranty.

imm ediatel y.
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 flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
eve ry two y ears. Always use new brake flu id
which conforms to Federal Motor Veh icle
Standard "F MVSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the b rake fluid changed by your author­
ized
Audi dealer . Your dealer has the correct
tools, the right brake fl uid 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 flu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifica tion
J 1 7 03 and conforms to
Federa l Moto r Ve hicl e Standard 1 16.
Always check with yo ur authorized Aud i
dealer to make sure yo u are using the
correct brake fluid. The correct type of brake f lu id is also ind icated on the
brake flu id 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
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safety. This cou ld resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
