206 Driving and en vir onm ent
Catalytic converter
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 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., 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 catalytic converter burns many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r 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 could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam
aged.
T his is espe cially true for ve hicles with low
s lung chassis (spor ts chassis)* and fully load
ed vehicles .
234 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:> &, .
&_ 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

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.
238 Checking and filling
Checking the engine oil level
Fig. 197 Disp lay: Oi l level indicator
Read oil level
• Park your vehicle so that it is horizontally
level.
.. Shut the engine off when it is at operating
temperature.
.. Switch only the ignition back on.
• Wait approx. two minutes.
> Select: ICARI function button> Oil level. Or
> Select: ICARI function button> Car sys-
tems *
control button > Servicing & checks >
Oil level.
• Read the oil leve l in the radio or MMI* Dis
play
r::;:, fig. 197. Add engine oil if the bar of
the oil level indicator is near "Min"
r::;:,page 238.
The oil level needs to be checked at regular in
tervals . The best times to do this are whenev
er you refuel and prior to long trips .
Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to a 1/2 quart per 600 miles (0.5
li
ter per 1,000 km). Consumption may be high
er within the first 3,000 miles (5,000 km).
@ Tips
The oil level indicator in the radio or MMI*
Display is only an information display. If
the oil level is too low, a minimum oil
warning appears in the instrument cluster.
Add oil
r::;:, page 238. If the hood has been
opened, the current oil level is shown in
the instrument cluster the next time the
ignition is switched on.

Audi dealer or other qualified workshop
to have excess oil extrac ted if necessary.
-Audi does not recommend the use of oil
additives. They may damage the engine ..,..
240 Checking and filling
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 sealed and generally re
quires little attention.
The cooling system has been filled at the fac
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-based coolant additive Gl3 ant ifreeze
with anticorros ion add itives (SO% for USA
models; 60% for Canadian models). This mix
ture both assures the necessary frost protec
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the coo l
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main
tain antifreeze protection and cooling efficien
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the veh i
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- - 31 °F ( - 35°() USA
- - 40°F ( - 40°() Canada .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 233.
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in
your vehicle is sufficient to meet the cli
mate cond itions. This is especially impor
tant if you live in a region where the w in- ter
is extreme ly cold . If necessary, in
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad
ditive Gl2++ or Gl3 for your vehicle.
This coolant additive is available at au
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor
rosion protection. The resulting corro
sion can ca use a loss of coolant and se
rious engine damage.
- Do not add any type of radiator leak seal
ant to your vehicle's engine coolant .
Add ing radiator repair fluid may adverse
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 199 Engine compartment : cover on t he coolant
expansion tank
Before you check anyth ing in the engine com
partment,
always read and heed all WARN
INGS c:> &. in Working in the engine compart
ment on page 233 .
.. Park your vehicle on a level surface .
.. Turn off the ignition .
.. Read the engine coolant level from the
coolant expansion tank
c:> fig. 199,
c:> page 235, fig. 196 . With a cold engine,
the coolant level should be between the
"MIN" and "MAX" markings. When the
engine is warm, the level may be slightly
above the "MAX" marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration ¢
page 235.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 30 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec
ommend 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
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
(D Note
Do not add any type of radiator leak seal
ant to your vehicle's engine coolant. Add
ing radiator repair fluid may adversely af
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ¢ A in Working in the engine compart
ment on page 233.
... Turn off the engine .
... Let the engine cool down.
Checking and filling 241
... Place a thick rag over the coolant expansion
tank ¢
page 240, fig. 199 and carefully turn
the cap counter-clockwise ¢
A.
... Add coolant.
... Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive
Gl2+
+, Gl3
or in an emergency Gl2 +. Do not use a
different additive . In an emergency use plain
water until you can get the correct additive and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex
cess coolant will be forced out through the
pressure relief valve in the cap when the en
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully
in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en
gine coolant can catch fire.
-Antifreeze is poisonous. Always store an
tifreeze in its original container and well
out of the reach of children.
