Misfuel Prevention (Diesel) - CITROEN C4 PICASSO Handbook

The petrol or Diesel engine of your vehicle is
fitted with a catalytic converter, a device 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 introduced.
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.
Fuel cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention (Diesel)*
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.
Operation
When a petrol filler nozzle is introduced into the
fuel filler neck of your 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.
* Depending on the country of sale.
It remains possible to use a fuel can to
fill the tank.
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 and pour
slowly.
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, we
recommend that you check with the
CITROËN dealer network, whether your
vehicle is suitable for the fuel pumps in
the country in which you want to travel.
