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¢ page 215,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 229, 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
¢page 229.
-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
II symbol for the diesel
particulate filter ill uminates ¢
page 22. ..,.
-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in the engine com
partment could start a fire.
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal in
jury while the engine is running or being
started, never touch :
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical ha zards c:::> & .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de
fects and reproductive harm. In addition ,
certain fluids contained in vehicles and
certain products of component wear con
tain or emit chemicals known to the
State of California to cause cancer and

cessories contain lead and lead com
pounds, chemicals known to the State of
California to cause cancer and reproduc
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam
age to vehicle systems will occur.
(® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If
you see spots from oil or other vehicle flu ids, have your vehicle inspected by an au
thorized Audi dealer.
Closing the engine hood
.,. Pull the hood down until the pressure from
the struts is reduced.
"'Let the hood
drop down and latch in place.
Do not try to push it shut; it may fail to en
gage

A WARNING
-
A hood that is not completely latched
could fly up and block your view while driv
ing .
- When you close the engine hood, check it
to make sure the safety catch has proper ly engaged. The hood should be flush
with the surrounding vehicle body parts.
- If you notice while driving that the hood
is not secured properly , stop at once and
close it. •

(D Note
Driving with an insufficient oil level is like
ly to cause severe damage to the engine.
@ Tips
- The oil pre ssure w arning di spl ay . is
n ot an indi cato r of the oil le vel. D o not
rely on it. Inste ad , c heck th e oil le vel in
y ou r engine at regula r inter vals, pref
er ably each t ime you refu el, and al way s
befor e going on a long tr ip .
- If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult your Audi
dealer to have the cause of yo ur conce rn
properly diagnosed. Keep in mind that
the accurate measurement of oil con
sump tion requires great care and may
take some time. Your Audi dealer has in
str uctions about how to measure oil con
sumption accurately.

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
q uir es lit tle atten tion .
The cooling system has been filled at the fac
tory with a pe rmanent coo lant which does not
need to be c hanged. The coolant consists of a
mixture o f spec ial ly conditioned water and the
manuf acturer 's glyco l-based cool ant ad di-
tiv e G13 antifreeze with ant icorros ion addi
tives (50% for USA models ; 60% for Canadian
mod els) . This mixture both assures the neces
sary frost protection and p rotect s metal com
ponents in the engine's coo ling system from
corrosion and scaling . It a lso raises the boil
i ng point of the coolant .
Do not reduce the concentration o f the coo l
ant in the summer by adding plain water.
The
proportion of coolant add it ive must be at
l e a st 50 % but not mor e than 60 %
to main
tain antifreeze protection and coo ling efficien
cy .
If the coolant frost protect io n is too low,
the coolant cou ld free ze and dam age the veh i
cle heating and eng ine cooling system.
For yea r-round driving, antifreeze is added at
the fac to ry for tempera tures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.
Checkin g and fillin g 231
If you must add coo lant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended.
_& WARNING
Before you c heck anything in the engine
compartment, always read and heed a ll
WARNINGS
c> .& in Working in the engine
comportment on page 224.
Q) 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 condi tions. This is especi ally impor
tan t if you live i n a region wher e th e win
ter is ex treme ly co ld. If necessary, i n
crease t he p ropo rtion of coo lant add itive
to 60% .
- Whe n ad ding coolant additive t o yo ur
c ooling sys tem, reme mbe r:
- We recommend using on ly coolant ad
d itive G12++ or G13 (check the labe l)
fo r your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs .
Ot he r ty pes of antifree ze can sign ifi
cantly reduce corros io n protection. The
r es ult ing co rrosion can ca use a loss of
coolan t and serious e ng ine damage.
- Do not add any ty pe of rad iator leak seal
a nt to yo ur vehicle 's engine c oolant .
A dd ing radia tor repair fl uid may adverse
ly affect the f unction and pe rformance of
your cooling system and co uld resu lt in

232 Check ing and filling
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 191 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com
partment,
a lwa ys re ad and h eed a ll WA RN
INGS o .A in Working in the engine compart
ment on page 224 .
., Park your vehicle on a level surface.
., Switch
off the ignit io n.
., Read the eng ine coolant level from the cool
ant expans ion tank
o fig . 191, o page 226,
fig. 188. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant exp ans ion tank
can be seen in the engine compartment illus
tration
o page 226.
To obtain an accurate read ing, the engine
must be switched
off.
The expans ion tank in your vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System
o page 17 will
illum inate unt il you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coolant .
In a
sea le d system, losses can occur 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
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap
plying light, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti
freeze or coolant on the exhaust system
or hot engine parts . Under certa in cond i
tions, the ethylene glycol in engine cool
ant can catch fire.
0 Note
Do not add any type of radiator leak seal
ant to your veh icle's engine coolant . Add
i ng radiator repa ir fluid may adverse ly af
fe ct the funct io n and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.
