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
reach the catalytic converter. This could re­
sult in over heating of the converter, requir­
ing
its replacement .

@) 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 properly.
Do not dump it on garden soil, wooded
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.
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 .

Read and follow the WARNINGS before check­
ing anything
in the engine compartment
Qpage236.
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
in cold. When the engine is warm it can be
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.
