Fuel adaptation
Flexifuel engines can be driven on both 95
octane unleaded petrol and bioethanol E85.
Both fuels are filled in the common fuel tank so
that any variations of mixing ratios between
these two fuels is possible.
If the fuel tank is filled with petrol after the car
has been driven on bioethanol E85 (or vice
versa) then the engine may run slightly
unevenly for a time. For this reason it is impor-
tant to allow the engine to accustom itself
(adapt) to the new fuel mixture.
Adaptation takes place automatically when the
car is driven for a short period at an even
speed.
IMPORTANT
After the fuel mixture in the tank has been
changed an adaptation should be made by
driving at an even speed for about 15
minutes.
If the battery has been discharged or discon-
nected then a slightly longer period of driving
is required for the adaptation as the memory
for the electronics has been cleared.
