Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
.. Always use lead-free gasoline i=> page 220,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 234, Adding engine oil
The catalytic converter is an eff ic ient "clean
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert
e r and proper functioning of the engine.
A WARNING
T he 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
areas 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 apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will al ready seriously de
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 234.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con
verter, requir ing its replacement .
- To assure efficient operation of the Emis
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
Cl symbol for the diese l
particulate filter i lluminates

236 Check ing and filling
@ 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
l y. Do not dump it on garden soi l, wood
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
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 sea led and generally re
qu ires little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer 's glycol-based coo lant add i-
tive G l3 antifreeze with ant icorrosion addi
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es
sary frost protection and protects metal com ponents in the engine's cooling sys tem from
corrosion and scaling . It a lso raises the boil
ing point of the coolant .
Do not red uce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add it ive mu st be at
l e a st 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficien
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld freeze and damage the veh i
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 228.
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli mate conditions . This is especia lly impor
tant if you live in a reg ion where the win
ter is ex treme ly cold. If ne cessa ry, i n
crease the pr opo rtion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c ooling sys tem, remembe r:
- We recommend using on ly coolant ad
d itive Gl2++ or Gl3 for your vehicle .
This coolant additive is availab le at au
thor ized Audi dealers . Other types of
ant ifreeze can s ignificant ly reduce cor
rosion protection. The resulti ng cor ro
sion can ca use a loss o f coolan t and se
rio us engine damage.
- Do not add any type of rad iator leak seal
a nt to yo ur vehicle 's engine coolant.
Add ing radiator repai r fl ui d may adverse
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by yo ur New Vehicle
Limited Warranty.

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 204 Eng ine compartme nt: cover o n the coolant
expansion tank
Before you check anything in the engine com
partment,
a lway s read and he ed all WARN
INGS ¢ & in Working in the engine compart
ment on page 228.
Park your vehicle on a level surface.
~ Switch off the ignition.
~ Read the engine coolant leve l from the cool
ant expansion tank¢
fig. 204, ¢ page 230.
With a cold engine, the coolant level should
be between the "min" and "max" markings.
When the engine is warm, the level may be sl ightly above the ''max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration ¢
page 230 .
To obtain an accurate reading, the engine
must be switched off.
The expansio n tank in your vehicle is equipped
with an electric coolant level sensor.
When t he coo lant level is too low, the warning
light in the Auto-Check System¢
page 15 will
illuminate unti l yo u add coolant and the level
has been restored to normal. Even thoug h
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool-
Checkin g and fillin g 237
ing system shou ld be inspected immediately
by your authorized Audi dealer . It is not
eno ugh merely to add coo lant .
In a
s ealed system, losses can occu r on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Red uce the risk of scald
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id a nd steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap
p lyi ng lig ht, dow nward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti
freeze o r coolan t on the exhaust system
or ho t engine parts. Und er certa in cond i
tions, the ethylene gly co l in engine coo l
an t can catch fire.
(D Note
Do not add any type of radiator leak sea l
ant to your veh icle's engine coo lant. Add
i ng radia to r repa ir flui d may adverse ly af
