Checking and Filling Fuel
Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converte r
and must only be d riven w it h
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter ­
gent Gasoline can be found on the offic ial web­
site (www .topt iergas.com).
The individ ua l gasoline grades a re differentiated
by
o ctane ratings . This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llow ing headings ma tch the correspon ding
sticker in the fue l filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regula r/ MIN. RON
91 Regular
Use reg ular gaso line wi th minim um 87 AK I/
91 RON ~ 0 .
The m aximum engine power is only reache d if
p rem ium gaso line 91 AKI/ 95 R ON is use d .
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M )/2
91 / SUPER MIN. RON 95
Using prem ium gaso line wit h minim um 91 AKI/
9 5 RON is recommende d.
If premium gasoline is not availab le, yo u can also
use reg ular gasoline 87 A KI/ 91 RO N. Howeve r
this does reduce t he engine powe r sli ght ly.
CD Note
- Fill ing the tank just one t ime with lead ed
fuel or o ther meta llic additives will cause
p erm anen t de ter io rat io n to the ca taly tic
c onve rter fu nctio n.
- W hen g asoline wi th an octane ratin g th at is

Checking and Filling
{!) Tips
The vehicle may be filled with fuel t hat has a
higher octane rating than w hat is requ ired by
the eng ine .
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline b lended with al­
cohol o r MTBE (commonly referre d to as oxygen­
a tes) if the blende d m ixt ure meets the fo llow ing
cr it e ria :
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than
3% metha-
nol.
- Blend must contain more than
2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol )
-Ant i-kno ck ind ex mus t be 87 AKI or hig her.
- Blend must not co nta in mo re than
15% etha-
nol.
Blend of gasoline and MTBE
- Anti-knoc k index must be 87 AKI or h igher .
- Blend mus t contain no t mo re than
15% M TBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to pe rform es­
pecially well for w inter or s ummer dr iving . D ur ­
i ng seasonal cha nge-ove r, we sugges t that yo u
fill up a t busy gas stat ions where the seasonal
adjus tme nt is mo re li ke ly to be m ade in time .
CD Note
- Metha nol fuels which do not meet these re ­
quireme nts may cause cor rosion and dam­
a ge to p last ic and r ubber co mpon ents i n t he
fue l sys te m .
- D o not use f ue ls tha t fa il to mee t the speci­
fie d cr iteria in thi s ch ap te r.

Checking and Filling
-If you a re 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 identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those specified are not the respon­
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties.
- If you experience a loss of fuel economy or
driveability and performance problems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on vital engine
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 information on TOP TIER Deter­
gent Gasoline, please go to the official website (www .toptiergas .com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your en­
gine of peak performance.
(D Note
Damage or malfunction due to poor fuel qual­
ity is not covered by the Audi New Vehicle
Limited Warranty.

Refueling
' Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
~ page 234.
You can find the fuel tank capacity of your vehicle in
~ page 291.
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fuel specifications, see
~ page 231.
Your vehicle fuel tank has an on board refuelling
vapor recovery system. This feature helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle . In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
.8, WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­ port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to
use for your lawn mower, snow blower, etc .,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
CI) Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Checking and Filling
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground
under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
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 regular­
ly .
It would be best to check each time you re­
fuel 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 235.
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
change 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
240
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:
& 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.
@I 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 .
