Note
- Fuels containing a high percentage of etha-
nol
such as ESQ and E85 may only be used in
vehicles with f lexible 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 corrosion and dam-
age to plastic and rubber components in the
fuel system.
-
Do not use fuels that fail to meet the speci-
fied criter ia 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 wh ich 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 fue
l
economy
or
driveability and performance problems due
to the use of one of these f uel blends, we
recommend that
you
switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies
to
vehicles: with
flexible fuel
engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap.
Vehicles with f lexible fuel engines may be operat-
ed with bio-ethanol
f
uels such as E85 (85%
et ha-
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95)
.
The vehicle may also be operat-
ed with a m ixt ure of these fuels.

Your f uel consumption wi
ll
increase when using
bio-ethano
l
fue ls due to the lower amount of en-
ergy contained per unit volume in ethano
l.
Warming up the fle xible fuel engine in low
t emperatu
res
Due to the chemical composition of bio-ethanol,
a certain amount of fue
l
ends up in the engine oil
when driving short distances in very low temper-
atures. This fuel evaporates again when the en-
gine is warmed
up.

Please w arm up eng

If
t
he driver message appears in the instrument
cluster disp lay, drive with a warm engine to
re-
duce the oil
level.

Note
-
Never fill with methano
l
or with a higher
percentage of bio-ethanol than 85% (E85).
A highe
r
percentage of bio-ethanol in the
fue
l
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 complete ly w ith unleaded
premium grade gasoline every 5,000 miles.
-
If you experience starting, rough idle or hes-
itat ion driveab
ili
ty problems, fill the fuel
tank complete ly w ith unleaded premium
grade gasoline and drive it normally unt
