ing hot parts. Tie back hair be­
fore starting, and wear no cloth­
ing that will hang or droop into
the engine.

When
adding fluids, always make
sure that they are poured into the
proper container or filler opening,
otherwise serious damage to ve­
hicle systems will occur. r:Gb To detect leaks in time, inspect
� the vehicle floor pen from under­
neath regular ly. If you see spots
from oil or other vehicle fluids, have
your vehicle inspected by an autho­
ri zed Audi Dealer .

Engine oil
Specification and viscosity
Yo ur engine was factory filled with an all
season high quality engine oil. If you need to
add oil between oil changes, use any high
quality petroleum- or synthetic-based oil
with correct specifications.
The following terms must appear on the oil
conta iner singly or in combination with oth­
er designations:
- API Service SJ
- ACEA A2 or ACEA A3
Engine oils are graded according to their vis­
cosity. The proper grade to be used in your
engine depends on existing climatic or sea­
sonal conditions.
The engine oil which was first put into your
engine has a viscosity grade of SAE OW--30.
You can use this oil over all temperature
ranges for normal driving. If engine oil vis­
costy grade SAE OW--30 is not available, you
can also use SAE 5W-30 or SAE 5W-40.
See your authorized Audi Dealer tor more in­
formation regarding oil for your vehicle.
234 I
B31-113C I
Engine oil identification symbol
Oils of the proper qualityforyour vehicle will
be identified with a new "starburst" sym­
bol A. The starburst symbol indicates that
the oil has been certified by the American
Petr oleum Institute (API). Another
oil identi fication symbol B could be
added to the oil container to help you select
the correct oil.
1 - The top portion indicates the oil quality
by API designations.
2 - The center portion shows the SAE oil
viscosity grade.
3- The lower portion indicates that the oil
has fuel saving capabilities.
Note
Look for one of these symbols on the
front of the oil container. and use
only oils that display these symbols.
Engine oil additives
Audi does not recommend the use of
oil additives. They may adversely af­
fect your New Vehicle Warranty.

Engine
oil consumption
The rate of the oil consumption depends on
the quality and viscosity of oil, the speed at
which the engine is operated, the climate,
and road conditions as well as amount of
dilution and oxidation of the lubricant.
Because of these variables, no standard
rate of oil consumption can be established,
but drivers should expect higher oil con­
sumption at high speeds and when the en­
gine is new.
Therefore, we recommend that you check
the oil level at regular intervals (for example,
each time you are refuelling, or before going
on a long trip).
If the oil level should go below the minimal
level, the check engine oil level warn­
ing light* in the instrument cluster will
come on. See page 144. You should check
the oil level using the oil dip stick as soon as
possible, and then top off the oil as neces­
sary. Notes
• The engine in your vehicle de­
pends on oil to lubricate and cool all
of its moving parts. Therefore the
engine oil should be checked regu­
larly and kept at the required level.
• Lack of sufficient engine oil may
lead to severe engine damage.
• The oil pressure warning light is
not an oil level indicator.
A Always
heed all WAR NINGS
� on page 232.
Checking the engine oil level
The best time to check the engine oil level
is when the oil is warm.
To get a true reading, the vehicle must be on
level ground.
A Always heed all WAR NINGS
� on page 232.
• After turning off the engine, wait a few
minu tes for the oil to return to the oil pan. VE
HICLE CARE
• Pull out dipstick (arrow) and wipe it clean
with a rag.
• Reinsert dipstick; push it all the way in.
• Pull dipstick out again and read the level:
a - Yo u must not add oil.
b- You can add oil. The oil level may go
into the a range, but riot above the a
range
c - You must add oil.
After filling in oil, make sure that the oil
level is somewhere within the b range.
• After checking the oil level, please make
sure that the dipstick is pushed back in all
the way.

Adding engine oil
A Always heed all WA RNINGS
r!!J on page 232.
• Turn off the engine.
• Unscrew the oil cap from the cylinder
head cover.
• Add oil by a half quart (half liter) at a time.
• Check the oil level with the dipstick.
:236 The
oil level must never be above the
"a .. range.
Otherwise oil could be drawn into the crank­
case breather and get into the atmosphere
through the exhaust system. The oil
would bum then In the catalytic con­
verter and cause damage.
� WARNING
Spilled oil is a fire hazard. The oil
filler cap must be secure to avoid
an oil spill.
• Carefully screw the oil cap back on and in­
sert the oil dipstick all the way. Otherwise
oil could leak out when the engine is run­
ning. Changing
the engine oil
The engine oil must be changed according
to the intervals specified in your Mainte­
nance booklet.
This is very important because the lubricat­
ing properties of oil diminish 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 distances, operate the vehicle in dusty
areas or under predominantly stop-and-go
traffic conditions, or have your vehicle
where temperatures remain below freezing
for exte nded periods.
Detergent additives in the oil will make
fresh oil look dark after the engine has been
running for a short time. This is normal and
is not a reason to change the oil more often
than recommended.

---------------------------------------------------VEHICLE CA
RE
�W ARNING
• If you must change the engine
oil in your vehicle:
• Wear eye protection.
• To reduce the risk of burns from
hot engine 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 running down your arm.
• Drain the oil into a container de�
signed for this purpose, one large
enough to hold at least the total
amount of oil in your engine. ,A
WARNING continued
• 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 wash­
ing thoroughly with soap and wa­
ter. �
BefoN changing your oil, first
make sure you know where you
can properly dispose of the old oil.
Always dispose of used engine oil
proper ly. Do not dump it on garden
soil, wooded areas, Into open
streams or down sewage drains.
Recycle used engine oi l by taking it
to a used engine oil collection facil­
ity in your area, or contact a service
station.
Because of the problem of proper
disposal, along with the special
tools and necessary expertise re­
quired, we strongly recommend that
you have your oil changed by an au­
thorized Audi Dealer or a qualified
workshop.
Always heed all WA RNINGS
on page 232.

Engine cooling system
The cooling system is sealed and generally
requires little attention.
The cooling system has been filled at the
factory with a permanent coolant which
does not need to be changed. The coolant
consists of a mixture of water and the
man ufacturer's coolant additive G 12 ABD
-ant ifreeze on a glycol base with anti-corro­
sion additives (50% for USA models; 60o/o
for Canadian models). This mixture assures
the necessary frost protection and protects
alloy 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 500fa but not more
than 600fa to maintain antifreeze protec­
tion and cooling efficiency.
238 For
year-r ound driving, antifreeze is added at
the factory for temperatures down to:
-31 °F (-35 °C) USA
-40 °F (-40 °C) Canada.
g Always heed all WA RNINGS
E!!1 on page 232.
Never use eny coolant additive
other than our G12 ABD additive
(check label) for your vehicle. This
coolant additive is available at au­
thorized Audi Dealers.
Other types of antifreeze can. above
all. significantly reduce corrosion
protection. The resulting corrosion
can cause a loss of coolant and
therefore serious engine damage. When
adding coolant additive to
your cooling system. please remem­
ber:
Under no circumstances may G12
ABD be mixed with other coolant ad­
ditives (for example G 11 ).
You can recognize G12 ABD in the
expansion tank by its red color. If
the liquid in the expansion tank is
brown, G 12 ABD has been mixed
with another coolant additive. In
this case. your vehicle's coolant
must be changed as soon as pos­
sible.
Note
Mixing coolant additives can result
in serious malfunction or engine
damage!

Checking the
engine coolant
level
The coolant expansion tank is located on the
left of the engine compartment -see il­
lustration.
The coolant level is automatically monitored
by the Auto-Check System -see page 141.
However, it is still recommended to check
the coolant lev�l visually from time to time
and always before going on a longer trip.
�W ARNING
To reduce the risk of being burned.
never open the hood if you see or
hear steam or coolant escaping
from the engine compartment.
Wait until no steam or coolant can
be seen or heard before carefully
opening the hood and following
the precautions on the next page.
Always heed all WA RNINGS
on page 232. To
obtain an accurate reading, the engine
must be switched off.
Since the expa nsion tank is transparent, the
cap need not be removed to check the cool­
ant level.
The coolant level must be between the
"MIN" and "MAX" marks when the en­
gine is cold and can be slig htly above the
"MAX" mark if the engine is warm. VE
HICLE CARE
The expansion tank in your vehicle is
equipped with an electric coolant level
checking device.
When the coolant level is too low, the warn­
ing light (see page 141) in the Auto-Check
System will blink until you add coolant and
the coolant level has been restored to nor­
mal.
Coolant losses
Coolant losses may indicate a leak in the
cooling system. In the event of coolant
losses, the cooling system should be in­
spected immediately by your authorized
Audi Dealer. It is not enough merely to add
coolant.
In a sealed system, losses can occur only if
the boiling point of the coolant is exceeded
as a result of overheating.
