06 Starting and driving
Starting the engine – Flexifuel
NOTE
Points to remember for carrying reserve
fuel:
In the event of stalling due to an empty fuel
tank, bioethanol E85 from a reserve fuel can
may make the engine difficult to start in
extreme cold. This is avoided by filling the
reserve fuel can with 95 octane petrol.
For more information on Flexifuel's bioethanol
E85 fuel, see page 276.
Fuel adaptation
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.
06
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.
