-Be aware that just one tank fi lling with
le aded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page229.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not switch off the ignition wh ile the
vehicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w it h lead-free super
grade gasoline .
Diesel particulate filter
Appl ies to vehicles : wit h diesel e ng in e
The diesel particulate filter fi lters nea rly a ll of
the soot part icles o ut o f the exhaus t. T he fi l­
ter cleans itse lf automatically under normal
driving conditions . If the fi lter cannot clean it-
Drivin g and en vironm ent 205
self (for example, because you are on ly driving
short distances), the fi lter becomes clogged
with soot and the
II symbol for the diese l
particulate filter illuminates

A WARNING
-Do not park your veh icle over flammable
mate ria ls such as grass or leaves because
the high temperature of the diesel par­ ticulate fi lter could start a fire.
- Do not apply an underbody protectant in
the exhaust system area or a fi re could
start.
Shutting down vehicle
If you would like your vehicle to rema in inop ­
erative for a longer per iod of t i me, contact an
Audi o r other spec iali zed dealer. They can ad­
vise you on necessa ry precautions e.g. co rro­
s ion p reven tion, maintena nce and s torage.
Pay attention to additional information con ­
cerning the battery . Refer to

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal d riving s tyle
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10-15 percent . T his sec ­
tion w ill give you some tips on how you can
help the env ironment and your poc ketbook. ..,_ •

228 Check ing and filling
Using the proper engine o il is important for
the functionality and service life of the en­
g ine. Your engine was factory-filled with a
h igh-quality oil which can usua lly be used
throughout the entire year.
0 Note
Your L imited New Vehicle Warranty does
not cover damage or ma lfunctions due to
fai lure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet.
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
standard spec ified for your veh icle's en­
gine. Using any other oil can cause seri­
ous eng ine damage.
- Do not mix any lubricants o r othe r addi­
tives into the eng ine o il. Doing so can
ca use engine damage.
If you need to add oi l and there is no ne
availab le tha t mee ts the Audi oil qua lity
s tandard your engine requires, yo u may
add a tota l of no more than 0 .5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gaso line engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- Vehicles with diesel engine: ACEA C3 or
API CF with a v iscosity grade of
SAE 0W-30 or SAE SW-30.
- For more information abo ut eng ine oil
that has been approved for your vehicle, please contact either your a uthorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site

Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all
of its moving ports .
In order to provide effective lubricat ion and
cooling of interna l eng ine components, all in­
ternal combust ion e ngines consume a certain
amount of oil. Oil consumpt ion va ries from
engi ne to engine and may change sig nifican tly
over the life of the engine. Typically, engines
with a spec ified break -in period (see
c> page 203) consume more oil during the
break-in period than they cons ume after oi l
consumption has stabilized.
U nder normal cond itions, the rate o f oi l con ­
s u mption depends on the q uality and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
condensation or fue l residue a nd the oxida­
t ion level of the oil. As any eng ine is subject to
wea r as m ileage builds up, t he oil co nsump ­
t ion may increase over time until replacemen t
of worn components may be come necessary.
With a ll these variab les coming into play, no
standard rate of oil consumpt io n can be es­
tabl ished o r spe cified . There i s no alte rnative
to regu lar and frequent che ck ing of the o il lev ­
el , see
Note.
If the yellow engine oil leve l wa rning symbo l
i n t he i nstr ument cluster
Ill lights up, you
sho uld check the oil leve l as soon as possib le
i=> page 229 . Top off the oil at your earliest
convenience

@ Tips
-The oil pressure warning display. i s
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 time you refuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oil, we r ecommend that you consult your Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. Your Audi dealer has in ­
structions about how to measure oil con­
sumption accurately.

sewage drains.
- 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 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 specially conditioned water and the
manufacturer 's glycol-based coolant addi-
tive G13 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
ing point of the coolant.
Do not reduce the concentration of the cool­
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 vehi­
cle heating and engine cooling system.
For year -round driving, antifreeze is added at
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. Mixing the coolant
additive with distill ed water is recommended .
Checking and filling 231
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~&.
in Working in the engine
compartment on page 225.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely 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 G12++ or G13 (check the label)
for your vehicle. This coolant additive is
available at authorized Audi dealers.
Other types of antifreeze can signifi­
cantly reduce corrosion protection. The
resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding 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.

232 Check ing and filling
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 225.
• Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the eng ine coolant leve l from the cool­
ant expansion tank
c> fig. 196, c> page 22 7,
fig. 193. 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"
ma rk ing.
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢
page 22 7.
To obtain an accurate reading, the engine
must be sw itched
off.
The expans ion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System ¢ page l 6 will
i l luminate unti l yo u 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 lea k in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your author ized 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 overheat ing.
A WARNING
T he cooling system is unde r pr essure and
c an get ve ry hot. Reduce t he risk of s cald­
ing from hot coolant by followi ng these
steps .
- T urn
off the engine and allow it to cool
dow n. -
Protect your face, han ds and arms from
escaping flu id and steam by cover ing the
cap with a large, thick rag.
- Tu rn the cap slowly and very care fully in
a counte r-clockwise direct ion while ap­
plying lig ht, 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 par ts. Under certa in cond i­
tions, th e ethylen e glyco l in engine coo l­
a nt can catch fire.
(D Note
Do not add a ny type o f radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator r epa ir fluid may adv erse ly af­
fe ct the funct io n and perfo rma nce of you r
co oling syste m and could result in damage
not covered by your New Veh icle Limi ted
War ran ty.

Brake fluid
Checking brake fluid level
Fig . 197 Engine compartment: cove r on the brake fluid
reservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢&. in Working in the engine compart­
ment on page 225.
,.. Read the brake fluid level from the brake
fluid reservoir¢
fig . 197, ¢ page 22 7,
fig. 193.
The brake flu id level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake flu id reservoir can be
seen in the engine compartment illust rat ion
¢ page 227.
The fluid level may drop
slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)/ . (Canadian
models) will come on¢
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two years . Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The correct type of
brake f luid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can seriously affect the effi­
c ie ncy of the brakes as well as your
safety. This could resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

29 6 Con sum er Inf ormation
-Always make sure the transmission se­
lector lever (automatic transmiss ion) is
in P (Park position) and the park brake is
applied .
@) For the sake of the environment
-Changing the engine settings wi ll ad­
versely affect em iss ion levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
