-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- 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
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- 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
fuel.
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
nea res t a uthor ized Audi dealer or author­
ized Aud i Serv ice Facility fo r ass istance .

Checking and Filling
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:

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 .
Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed. ..,.
