- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­

- If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended

Gasoline additives
A ma jo r concern among many auto manufactur ­
e rs is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu ­
facturer to ano ther, they have certain things in
common . All gasoline grades contain substances
that can cause deposits to collect on v ita l eng ine
parts, such as fuel injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com) .
Check ing and Filling
After an extended period of using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine of peak performance.
(D Note
Damage or ma lf u nction due to poor fuel qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel fuel w it h concentrations of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel info rmation for e asy recog nition by
the user.
If the d iesel fue l pump is not labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be sure to check befo re t raveling to
other countries .
UL SD No . 2 can become thic ke r i n ve ry cold tem­
peratures, and th is can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
soley for use with ULSD No . 2 . Therefore,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
cove red by your New Vehicle Limited War­
r a nty.
- If you put a ny amo unt of incorrect fuel in
the fuel tank, do not sta rt the eng ine under
any circumstances. Imme diately contact the

Ch eck ing and Filling
Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (cataly tic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner.
.,. Always use lead-free gasoline c:> page 190 , Fuel
supply.
.,. Never run the tank down all the way to empty .
.,. Never put too much motor o il in your engine
c:> page 203, Adding engine oil.
.,. Never try to push- or tow-start your vehicle.
The catalytic co nverter is an efficient "clean -up"
device built into the exhaust system of the ve hi­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
portant for the life of the catalytic converte r and
prope r funct ion ing of the eng ine .
_&. WARNING
The tempera ture of t he exhaus t sys tem is
h igh, bot h when driv ing and a fter stopping
the engine .
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact with dry grass, b rush, fuel spill or
other material which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields . D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter .

system the next time the ignition is
switched on.
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1 ,000 km),
depending on driving style and operating
conditions . Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
cause 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 .
Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­
tion.
Before you check anything in the engine compart ­
ment ,
always read and heed all WARNINGS q .&.
in Working in the engine compartment on
page 198.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances , operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
chang e the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information:
204
A WARNING
-
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
-
oil, let the engine cool down to the touch .
- When removing the oil drain plug with your
fingers, stay as far away as possible. Always keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm .
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin . Always protect your
skin by washing oil off thoroughly with soap
and water.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure you know where you can properly dispose of
the used oil.
- Always dispose of used engine oil properly .
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .

General information
.,. Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,. Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D N ote
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons . Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
2 10
and b raking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.
