Fu e l and R e fu e li n g
Many gasoline grades are blended to perform es -
pecia lly we ll for winter or summer driving . Dur-
ing seasonal change-over, we suggest that you
fill up at busy gas stations where the seasonal
adjustment
is more likely to be made in time.

Note
- Fuels containing a high percentage of etha-
nol such as ESO and E85 may only be used in
vehicles with flexible fuel* engines. Using
high ethanol fuel in vehicles not equipped
with flexible fuel* engines can cause severe
engine damage.
- Methanol fuels which do not meet these re-
quirements may cause corros io n and dam-
age to plast ic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i-
fied criter ia in this chapter.
- If you a re unable to determine whether or
not a particular fuel blend meets the spec i-
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for wh ich the contents can-
not be identified.
- Fuel system damage and performance prob-
lems result ing from the use of fue ls diffe r-
ent from those specified are not t he respon-
sibility of Audi and are not covered under
the New Vehicle or the Emission Control
System Warranties .
- If you experience a loss of fue l economy o r
driveability and performance prob lems due
to the use of one of these fuel blends, we
recommend that you switch to unblended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to: vehicles with flex ible fuel engine
You con recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flop.
Vehicles with flexible fuel engines may be oper-
ated w ith bio-ethanol fuels such as E85 (85%
ethanol and 15% gasoline) or with un leaded gas-
oline (91 AKI/ROZ 95). The veh icle may also be
operated with a mixture of these fuels .

Your fuel consumpt ion will increase when using
bio-ethano l fue ls due to the lower amount of en-
ergy contained per un it volu me in ethanol.
Warming up th e fle xible fuel engine in low
temperatures
Due to the chemical composition of bio-ethanol ,
a certain amount of fuel ends up in the eng ine o il
when driving short distances in very low temper-
atures. This fuel evaporates again when the en-
gine is warmed up .
II
Please warm up engine .
If the drive r message appears in the instr ument
cluster disp lay, drive with a warm engine to re-
duce the oil leve l.

Note
- Never fill with methano l or with a higher
percentage of bio-et hanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fuel can cause damage to the engine or to
the fuel system.
- If you use on ly E85, it is recommended
to
fill the fue l tank comp lete ly with unleaded
premium grade gasoline every 5,000 mi les.
- If you experience starting, rough id le or hes -
itat ion driveab ility prob lems, f ill the fuel
tank comp lete ly with unleaded prem ium
grade gaso line and drive it no rma lly until
the gaso line is used. See your author ized
Audi dealer if the prob lem pers ists.
- Inform your author ized Audi dealer that you
are operat ing or have operated the vehicle
with E85.
- Read and follow the informat ion and tips
