It is very important that your emission control
system (catalytic converter) is functioning prop
erly to ensure that your vehicle is running in an
environmentally sound manner .
... Always use lead-free gasoline c:> page 267, Fuel
supply.
... Never run the tank down all the way to empty.
... Never put too much motor oil in your engine
c:> page 2 76, Adding engine oil 'l:::r. .
.,. Never t ry to push- or tow-start your vehicle.
The catalytic converter is an efficient "clean-up"
device built into the exhaust system of the vehi
cle . The catalytic conve rter burns many of the
pollutants in the exhaust gas before they are re
l eased into the atmosphe re.
The exclusive use of unleaded fue l is critically im
portant for the life of the catalyt ic converter and
proper functioning of the engine.
.&, WARNING
T he temperature of the exha ust system is
high, both when driving and afte r stopping
the engine .
-
-Never to uch the exha ust tail pipes once they
have become hot . This could result in bu rns.
- Do not park o r operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, br ush, fuel spill or
other material which can cause a fire .
- Do not apply additional undercoating or rustproofing on or near the exhaust mani
fold, exhaust pipes, catalytic converter or
heat shields. During dr iving, the substance
used for undercoating could overheat and
cause a fire .
(D Note
-Be aware that just one tank filling with
leaded fuel will already ser iously degrade
the performance of the catalytic converter.
- Do not exceed the correct eng ine o il level
c:> page 2 76.
- Do not drive until the fuel tank becomes
complete ly empty. The engine co uld mis-

fire. Unburned fue l co uld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not switch off the ignition whi le the vehi
cle is moving .
- Do not continue to ope rate your vehicle un
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re
sult in overheat ing of the converter, requir
ing its replacement .
- To assure efficient operat ion of the Emis
sion Contro l System :
- Have yo ur vehicle maintained p roperly and
in accordance with the serv ice recommen
dat ions in yo ur War ranty
& Ma intenance
booklet .
- L ack of proper ma intenance as well as im
proper use of the veh icle w ill impa ir the
function o f the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emiss ion Control System is op
erating properly, the exhaus t gas can have a
su lfur-like exhaust gas sme ll under some op
erating states. This depends on the sulfur
content of the fuel being used. Us ing a differ
ent brand of fuel may help, or fil ling the tank
with lead-free super grade gasoline.
Engine compartment
Working in the engine compartment
Special care is required if you are working in the
engine compartment
For work in the engine compartment such as
chec king and filling fluids , there is a risk of in
jury , scalding, ac cident s, and burn s. For thi s
reason , follow all the warnings and general
safety p recauti ons provi ded in the following in
formation. The engine compartment is a dan
gerous area on the vehicle.

Checking and Filling
have the cause of your concern properly di
agnosed. Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
A pp lies to: ve hicles w ith oil leve l indicator
The engine oil level can be checked in the Info
tainment system
Observe the safety precautions c:::> &. in Working
in the engine compartment on page 2 71.
.. Park your vehicle on a level surface.
.. Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
.. Select: the
ICARI function button > Car systems
control button > Servicing & checks> Oil level.
.. Read the oil level in the display . Add engine oil
if the bar in the oil level indicator is just before
"min"
<=:> page 276.
The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km), de
pending on driving style and operating condi
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this, the
engine oil level must be checked regularly. It
would be best to check each time you refuel your
vehicle and before long drives.
@ Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in
strument cluster. Add oil and close the hood.
The current oil level is displayed in the Info
tainment system the next time the ignition is
switched on .

A WARNING
- When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of afire.
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
- Check the oil level. If the message Please
reduce oil level
appears, contact an author
ized Audi dealer or authorized Audi Service
Facility to have excess oil extracted if neces
sary.
- Do not mix any additional lubricants into
the engine oil. Damage caused 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.

Coolant addit iv e
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the fo llow
ing coolant additives .

G12++ TL 774 G
These additives may be mixed with each other.
The amount of coolant additive that needs to be
mixed w ith water depends on the climate where
the vehicle will be operated . If the coolant addi
tive percentage is too low, the coo lant can freeze
and damage the engine.

(D Note
-Before the start of winter, have your author

F ac ility check if the coolant additive in you r
vehicle matc hes the percentage appropriate
fo r the clim ate. This is espe cially important
when driving in colder climates .
-If the appropriate coolant addi tive is not
available in an emergency, do not add any
other additive for risk of damaging the en
