Diesel Misfuel Prevention - PEUGEOT 308 2020 Handbook

Practical information
► Take care to select the pump that delivers the
correct fuel type for your vehicle's engine (see a
reminder label on the inside of the filler flap).
► Insert the key into the filler cap, if your vehicle
has a standard key.
► Turn the filler cap to the left.
► Remove the filler cap and hang it on its
carrier (on the filler flap).
► Insert the nozzle as far as it will go (pressing
against the metal non-return valve A).
► Fill the tank. Do not continue past the
third nozzle cut-off, as this may cause
malfunctions.
► Put the filler cap back in place and close it by
turning it to the right.
► Push the fuel filler flap to close it (your
vehicle must be unlocked).
Your vehicle is fitted with a catalytic converter, a
device which helps to reduce the level of harmful
emissions in exhaust gases.

For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting petrol
nozzles only.
If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct fuel
before starting the engine.
For the THP 225 S&S EAT8 engine, the use
of RON98 unleaded petrol is recommended to
ensure optimum engine performance.
Fuel cut-off
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.

Diesel misfuel prevention

Mechanical device which prevents filling the tank
of a Diesel vehicle with petrol. It avoids the risk
of engine damage that can result from filling with
the wrong fuel.
Located in the filler neck, the misfuel prevention
device appears when the filler cap is removed.
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 instead insert a Diesel
filler nozzle.
It is still possible to use a fuel can to fill
the tank slowly.
In order to ensure a good flow of fuel, do
not place the nozzle of the fuel can in direct
contact with the flap of the misfuel prevention
device.
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.
