206 Driving and en vir onm ent
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 222,
Gasoline .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 236, Adding engine oil 'l=r. .
.. Never try to push- or tow-start your veh icle.
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 o f 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 sh ields . During driving, the
substance used for u ndercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 236.
-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 turn off the ignition while the ve
hicle 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 i lluminates
i=> page 34. ..,.
232 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to P (Park).
- Always let the engine cool down. Hot components will burn skin on contact.
- 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 care
fully opening the hood.
- Keep children away from the engine com partment.
- Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never touch the radiator fan. The auxili
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool
ant system is pressurized and hot cool ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri
cal system is necessary:
- 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 of automatic trans
mission 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 hazards
c:> &, .

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.
236 Checking and filling
(D Note
Driving with an insufficient oi l level is like
ly to ca use seve re damage to the eng ine.
@ Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead , check the oil level in
your engine at regular intervals, pref
erably each t ime you refuel, and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amo unts of oi l, we
r ecommend that yo u consult an author
i zed Audi dealer to have the cause of
you r concern p rope rly diag nosed. Keep in
mi nd t hat t he ac curat e measure ment of

Never mix oil additives with your engine
oil. These additives can damage your en
gine and adversely affect your Audi Limit
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper
l y. Do not dump it on garden so il, wood

- 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
q ui res little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion addi
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil
i ng po int of the coo lant .
Do not red uce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficie n
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35° C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .
.&, WARNING
--
Before you c hec k anyth ing in the engine
compartment, a lways read and heed a ll
WAR NIN GS~ .&.
in Working in the engine
compor tment on page 231 .
(J;) Note
-Before winter sets in, have the coo lant
checked to see if the coolant additive in
yo ur vehicle is sufficient to meet the cli
mate condi tions . This is especia lly impor
tant if you live in a region where the win
ter is extreme ly co ld . If necessary, in
crease the p roportion of coo lant add itive
to 60%.
- When adding coolant additive to yo ur
cooling system, remember :
- W e r ecommend using o nly coola nt ad
d itive G l2++ or Gl3 for your veh icle.
T his coolan t additive is av ail ab le a t au
thor ized Audi dealers. O ther types of
antifreeze can significant ly reduce cor
rosion protection . The resulti ng cor ro
sion can cause a loss o f coolant and se
rious engine damage.
- Do not add any type of rad iator leak seal
ant to your vehicle 's eng ine coolant.
Add ing radiato r repair flu id may adverse
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not cover ed by yo ur New Ve hicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .

Before you check anything in the engine com
partment,
a lway s re ad and he ed all WARN
INGS ¢ A in Working in the engine compart
ment on page 231 .
.,. Park your vehicle on a level surface.
.,. Turn off t he ignit ion.
.,. Read the eng ine coolant level from the cool
ant expansion tank¢ fig . 201, ¢ page 233,
fig. 198 . With a cold eng ine , the coola nt
level should be between the "M IN " and
"MAX" markings . W hen the eng ine is warm,
the leve l may be slightly above the "MAX"
marking.
The location of the coolant expans ion tank
can be seen in the engine compartment illus
tration ¢page 233.
To obtain an accurate read ing, the eng ine
must be switched off.
The expans ion tank in your vehicle is equipped
with an e lectr ic coolant level sensor .
When the coo lant level is too low, the warning
light in the Auto -Check System ¢ page 30 will
blink until you add coo lant and the level has
been restored to normal. Even though there is
a n elec tric coolant leve l sensor, we s till rec
ommend you chec k 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-
Checkin g and fillin g 239
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.
(D Note
Do not a dd any type o f radiator leak se al
ant to your veh icle's engine coo lant. Add
ing radiator repa ir flui d may adverse ly af
fect the funct ion and performance of yo ur
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.
