Many gasoline grades are blended to perform es-
pecially well for winter or summer driving. Dur-
ing seasona l change-over, we suggest that you
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in t ime.
- Fuels containing a high percentage of etha -
nol such as ESO and E85 may only be used in
vehicles with flexible fuel* eng ines. Using
high ethanol fuel in vehicles not equ ipped
with flexible fuel* engines can cause severe
engine damage .
- Methanol fuels which do not meet these re-
quirements may cause corros ion 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 crit eria in this chapter.
- If you are unable to determine whether or
not a particular fue l blend meets the spec i-
ficat ions, ask your service station or its fuel
su pplier.
- Do not use fue l for which the contents can-
not be identified.
- Fuel system damage and performance prob-
lems result ing from the use of fue ls differ-
ent from those specified are not t he respon-
sibility of Audi and are not covered under
the New Vehicle or the Emission Contro l
System Warranties .
- If you experience a loss of fue l economy or
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)
App lies to vehicles: with flexib le 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 with bio-ethanol fuels such as E85 (85%
ethano l and 15% gasoline) or with un leaded gas-
oline (9 1 AKI/RO Z 95). The vehicle may also be
ope rated with a mixture of these fuels.
Fuel and Re fueling
Your fuel consumpt ion will increase when using
bio-ethano l fue ls due to th e lower amount of en-
ergy conta ined per unit volume in ethanol.
Warming up the flexible fuel engine in low
temperature s
Due to the chemica l composition of bio-ethanol ,
a certa in 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 warm up eng ine.
If t he driver message appears in the instr ume nt
cluster disp lay, drive with a warm engine to re-
duce the oil level.

Note
- Never fill wit h metha nol or with a higher
percentage of bio-ethanol 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 complete ly with unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes -
itat ion driveability prob lems, fill the fuel
tank complete ly with unleaded premium
grade gaso line and drive it norma lly until
the gaso line is used. See your author ized
Audi dea ler if the problem persists.
- Inform your author ized Audi dealer that you
are operating or have operate d the vehicle
with E8S.
- Read and follow the informat ion and tips

Tips
It may take longer to start the engine when
the outs ide temperatu re is very cold. If possi-
