Checking and Filling
Checking and Filling Fuel
Gasoline grade
A pp lies to: ve hicles w ith gasoline engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .toptiergas.com).
The individual gasoline grades are differentiated
by
octane ratings. This value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regular gasoline with minimum 87 AKI/
91 RON
i::>@ .
The max imum eng ine power is only reached if
p rem ium gasol ine 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gaso line with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also use regular gasoline 87 AKI/ 91 RON . However
this does reduce th e engine powe r slight ly.
0 Note
- Fillin g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deter iorat ion to the catalytic
converter function.
- When gasoline with an octane rat ing that is
too low is used , h igh speeds or heavy engine
load can lead to engine damage.
310
(D Tips
The vehicle may be filled with fuel that has a
h igher octane rating than what is required by
the eng ine.
Blended gasoline
App lies to : vehicles wi th gaso line e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher.
- 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)
-Anti-knock index must be 87 AK I or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur­
i ng seasonal change-over, we suggest that you
fill up at busy gas stat ions where the seasonal
adjustment is more lik ely to be made in t ime.
@ Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not u se fue ls that fail to meet the speci-
fied criteria in this chapter.

fue l conta iners in t he ve hicle. Fue l cou ld leak
out of the container and ignite, espec ially dur ­
ing an accident. This can cause exp losions,
fires and injuries .
- If you must transport fuel in a fuel contain ­
er, please note the following:
312
- Always place a fue l container on the
ground before fill ing . Never fill the fuel
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
while refueling and the fuel vapors could i gnite .
- For fuel containers made of metal, the fuel pump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,

The most important check points .
-For safety reasons, the hood must always be
latched securely while dr iving. Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners cannot
be lifted .
-If you notice that the hood is not latched
while you are driving, stop immed iate ly and
close it, because d riving when the hood is
not latched increases the r is k of an accident.

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 anyt hing in the eng ine compart ­
ment,
alwa ys read and heed all WARNING S¢.&.
in Working in the engine comportment on
page 314.
The engine oil must be changed accord ing to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if you drive most ly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic condit ions, 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. Th is 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
qu ired, we strongly recommend that you have
your oil c hanged by an authorized
A udi de aler or
a qualified service station .
If you choos e to change your o il y our self , please
note the following important information:
A WARNING
T o red uce the r isk of pe rsonal injury if yo u
must change the engine oil in your ve hicle
yourse lf:
-Wear eye p rotection.
-To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
-Whe n removing the o il drain plug with your
fingers, stay as far away as poss ible. A lways
Ch eck ing and F illing
keep your forearm pa rallel to the ground to
he lp prevent hot oil from running down your
arm.
-Drain the oil into a container designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
-Engine oil is poisonous. Keep it well out of
the reach of children.
-Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
a nd water.
@ Note
Never mix oil additives with yo ur engine oil.
These additives can damage your engine and
adverse ly affect your Audi limited New Vehi­
cle Warranty.
@) For the sake of the environment
-Before chang ing your oi l, first ma ke sure
you know where you can properly d ispose of
the used oil.
-Always dispose of used engine o il properly.
Do not dump it on garden so il, wooded
areas, into open streams o r down sewage
dra ins.
-Recycle used eng ine o il by tak ing it to a used
eng ine oi l collec tion fac ility in yo ur area, or
