nozzle; as this may cause malfunctions.
►

Put the filler cap back in place and turn it to
the right (depending on version).
►


Push the filler flap to close it.
The vehicle is fitted with a catalytic converter,
which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be inserted.
If you have put in the wrong fuel for
the vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

When a petrol filler nozzle is introduced into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
The misfuel prevention device does not prevent filling with a jerrycan, regardless
of the fuel type.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a PEUGEOT dealer if the vehicle
is suitable for the distribution equipment of the
countries visited.
