vehicles running on ethanol-based
fuel
It is essential to use unleaded petrol or
fuel containing a maximum of 85% eth-
anol (E85).
In very cold conditions, it may be very
difficult or even impossible to start the
engine. To avoid this problem, use un-
leaded petrol or, for equipped vehi-
cles, use the heater integrated into the
engine: connect the specified end of
the extension piece supplied into the
socket integrated into the radiator grille
and the other end into a 220v socket
for at least 6 hours before starting.
Note: you may notice an increase in
fuel consumption with this type of fuel.
filling with fuel
Insert the nozzle to open valve B and
insert it fully before turning it on to fill
the fuel tank (risk of splashing).
Keep the nozzle in this position through-
out the entire filling operation. When
the pump cuts out automatically at the
end of the filling procedure, a maximum
of two further filling attempts may be
made, as there must be sufficient space
in the fuel tank to allow for expansion.
Make sure that no water enters the fuel
tank during filling. Valve B and its sur-
round must remain clean.
petrol versions
Using leaded petrol will damage the
antipollution system and may lead to a
loss of warranty.
To ensure that the fuel tank is not filled
with leaded petrol, the fuel tank filler
neck contains a restrictor fitted with a
foolproof system which only allows
the nozzle for unleaded petrol to be
used (at the pump).
