Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure
that your vehicle is running in on
environmentally sound manner.
.,.. Always use lead-free gasoline Q page 231, Gas­
oline grade .
.. Never run the tank down all the way to empty.
.. Never put too m uch motor oil in your engine
Q page 240, Adding engine oil "t::r..
.. Never try to push-or tow-start your vehicle.
The
catal ytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi­
cle. The catalytic
converter burns many of the
pollutants in the exhaust gas before they are re­
leased into
the atmosphere .
Checking and Filling
The exclusive use of unleaded fuel is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
f= - I
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never
touch the exhaust tail pipes once they
have become hot. This could result in burns.
-Do not park or operate the vehicle in a reas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire .
-
Do not appl y additional undercoating or
r ustproofing on or near the exhaust mani­
fold, exhau
st pipes, catalytic converter or
heat shields. During driving, the substance
used for un dercoating could overheat and
cause a fire.
CD Note
-Be aware that just one tank filli ng with
leaded fuel w ill already seriously degrade
the performance of th e c atalytic converter .
-
Do not exceed the correct engine oil leve l
Qpoge240 .
-Do not drive until the fuel tank becomes
completely empty. The engi ne could mis­
fire. Unbu r
ned fuel coul d also get into the
exhaust system and this could cause the
ca ta lyt ic co nver ter to overheat.
-Do not swi tch off the ignition whil e the vehi ­
cl e is moving .
-
Do not continue to operate your vehi cle un­
der these condi tions, as o therwise fuel c a n

Engine oil specifications
The engine oil used must conform to exact speci­
fications.
The ser vice interva l disp lay in the instrument
cluster of your vehicle will inform you when it is
time for an oil change . We recommend that you
have your
oil changed by an authorized Audi Serv­
ice Advisor.
If you have to top off the oil between oil changes,
use the Audi oil quality standard specified in the
table.
Audi oil quality standard
G
asoline VW S02 00 or
engin e vw S0400
Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled
with a high-quality oil
which
can usually be used throughout the entire
year.
CD Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
-
Use only a high quality engine oil that ex-
pressly complies
with the Audi oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
-
Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
Tips
If you need to add oil and there is none availa­
ble
that meets the Audi oil quality standard
your engi
ne requires, you may add a tota l of
no more than O.S qt/l of a high-quality "syn­
thetic" oil that meets the following spec ifica­
tions.
Checking and F illing
-ACEA A3 or API SM with a viscosity grade of
SAE OW-30, SAE SW-30 or SAE SW-40.
-For more information about engine oil that
has been approved for your vehicle, please

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 cool­
i ng
of internal engine components, all internal
combustion engines consume a certa in amount
of oil. Oil consumption varies from engine to en­
gine and may change significantly over
the life of
the engine. Typically, engines with a specified
break-in period
(see~ page 56) consume more
oil during the break-in period than they consume
after oil consumption has stabilized.
Under normal cond it ions, the rate of oil con­
s u
mption depends on th e qu ality and viscos ity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem­
perature and road conditions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the
oil. As any engine is subject to wear as mileage
builds
up, the oil consumption may increase over
t ime
until replacement of worn components may
become necessary.
With all these variab les coming into play, no
standard rate
of oil consumption can be estab­
lished
or specified. There is no alternative to reg­
ular and frequent checking of the oil level, see
Note .
If the yellow engine oil level warning symbol II
in the instrument cluster lights up, you should
check
the oil level as soon as possible
~page 240. Top off the oil at your earliest con-
venience

1-
-When adding oil, do not let oil drip onto hot
engine components. Th ere 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 r unning, because this is
a fire
hazard.
- Always clean skin thoroughly if it comes into
co ntact with engine oil.
«I) Note
-The oil level must not be above the@
range, because this can cause damage to
the catalytic converter or the engi ne. Con­
tact an authorized Audi dealer or authorized
A udi Service Facility to have excess oil ex­
tracted if necessary.
-
Do no t mix any additional lu bricants into
the engine oil. Damage cause by such addi­
tives 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
disposi ng of empty oi l containers.
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service
sta­
tion.
Before you check anything in the engine compart­
ment, alwa y s read and heed all WARNINGS
~page236.
The engine oil must be changed accord ing to the
intervals specified i n your Warranty & Mainte­
nance booklet. This is very important be cause the
lubricati ng properties of o il d iminish gradually

If you choose to change your oil yourself, please
note the following important information:
A WARNING
~ -
To reduce the risk of personal injury if you
must change the engine oil in you r vehicle
yourself:
-
Wear eye protection.
- To reduce the risk of burns from hot engine
oil, let th e 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 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.

-Before changing your oil, first make sure
you know where you can properly dispose of
the used oil.
- Always
dispose of used engine oil properly.

Coo Ling 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
q uires
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
specially conditioned water and the manufactur­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This mixture
both assures the necessary frost protection and
protects metal components in the engine's cool­
ing
system from corrosion and scaling. It also
raises
the boiling point of the coolant.
Do not reduce the concentrat ion of the coolant in
the summer by addi ng p la in water. The propor­
tion of coolant additive must be at least 50°/o
but not more than 60°/o to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system.
For year-round driving,
antifreeze is added at the
factory for temperatures down to:
- -
31 °F ( -35 °C) USA
- -40 °F ( -40 °C) Canada.
242
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled
water is recommended.
A WARNING
~ h . Before you check anything in t e engine com-
partment, always read and heed all WARN­
INGS C)page 236.
CD Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in you r
vehicle is
sufficient to meet the climate con­
d itions. This is especia l
ly important if you
live
in a regio n where the winter is extre m e­
ly cold . If necessary, increase the proportion
o f coo la
nt ad ditive to 60o/o.
-When add ing coolant additive to your cool­
ing
system, remember:
-We recommend using only coolant addi­
tive G12++
or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage.
-Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra­
dia to r repair fluid may adversely
affect the
func tion and performance of your cooling
system and could result in damage not cov ­
ered by your New Veh icle Limited W arranty .

Checking the engine coolant level
""Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q page 238, fig. 184. The coolant level
must be between the markings when the en­
gine

slightly above
the upper marking.
Adding coolant
Requirement: there must be a res idual amount of
coo l
ant in the expans io n tank c:?(i) .
""Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew
the cap counterclockwise
c:?,8..
""Add coolant mixed in the correct ratio
i:?page 242 up to the upper marking.
""Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au­
thorized
Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi­
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch
on even if
the ignition is switched off, which
increases
the risk of personal injury.
CD 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
continu e driving. See an authorized
Audi dea l­
er or authorized
Audi Service Facility for assis­
tance.
Radiator fan
The radiator fan switches on automatically by it­
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en­
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.

Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired
and the ne cessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
Battery
General information
The battery in your Audi does not need any main­
tenance under normal operating conditions. Audi
recommends having the electrolyte level check
by an
authorized Audi dealer or authorized Audi
Service Facility
when there are high outside tem­
peratures or when driving all day. The electrolyte
level should also be checked each time the bat­
tery is charged ~page 247.
Have the battery checked when you bring your ve­
hicle
in for an inspection . It is a good idea to re­
place
the battery if it is more than S years old.
Sometimes when the airbags deploy, the battery
will be disconnected from the vehicle electrical
system for safety reasons ~.&in Repair, care
and disposal
of the airbags on page 203.
Disconnecting the battery
The battery should not be disconnected. Several
vehicle functions (power windows, for
example)
will be lost when the battery is disconnected. The
functions must be reprogrammed after connect­
ing the battery. To avo id this, the battery should
only be disconnected from the vehicle electrica l
system when it is absolutely necessary.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for several days or
weeks, electrical consumers are gradually scaled
back
or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time~ page 92. Some convenience
functions, su ch
as interior lighting or power seat
adjustment, may not be available under certain
circumstances. These convenience functions will
be available again once you switch
the ignition on
and start the engine.
Checking and Filling
Winter operation
A lot of stress is placed on the battery during
cold weather, which results in reduced starting
ability. Have the battery checked and recharged if
necessary
before the cold weather begins.
A WARNING
- Work on the battery requires expert know l­
edge. Contact an authorized Audi dealer or
authorized Audi Service Facility for informa­
tion regarding the vehicle battery. There is a
risk for chemical
burns or explosions.
- Never
open the vehicle battery. Do not try to
change the battery electrolyte level. Other­
wise explosive
gas will escape from the bat­
tery and increase the risk of an exp losion. ___ ....J
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
in the luggage compartment, read and heed all
