Practical information -> Misfuel prevention (Diesel) for Your Citroen Berlingo SUV Third Generation (2018-2025)

Practical information  
► Put the filler cap back in place and close it by  
turning to the right.  
► Push the fuel filler flap to close it (your  
vehicle must be unlocked).  
If the fuel filler flap is open, a device  
prevents the left-hand side door from  
opening.  
The door can be opened half-way, however.  
Close the fuel filler flap to regain use of the  
door.

The vehicle is fitted with a catalytic converter,  
which helps to reduce the level of harmful  
emissions in the exhaust gases.  
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.  
► With a conventional key, insert the key into  
the filler cap, then turn the key to the left.  
If the vehicle is equipped with a sliding  
door on its left-hand side, do not open it  
while the fuel filler flap is open. Otherwise,  
there is a risk that the fuel filler flap and the  
sliding door may be damaged and the person  
filling up may be injured.  
Fuel cut-off  
Your vehicle is fitted with a safety system that  
cuts off the supply of fuel in the event of an  
impact.  
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.  
► Unscrew and remove the filler cap, then  
place it on the holder located on the fuel filler  
flap.  
If the fuel filler flap is open, a device  
prevents the left-hand side door from  
opening.  
► Insert the nozzle and push it in fully (while  
pushing on the metal valve A).  
► Fill the tank. Do not continue past the  
third cut-off of the nozzle, as this may cause  
malfunctions.  
The door can be opened half-way, however.  
Close the fuel filler flap to regain use of the  
door.

Practical information  
Operation  
– Never work on the orange high voltage  
cables or on any other high voltage  
component marked with the Electric risk label.  
Any intervention on the high voltage system  
must be carried out by qualified persons in  
workshops qualified and approved to carry  
out this type of work.  
– Never damage, modify or remove the  
orange high voltage cables or disconnect  
them from the high voltage network.  
– Never open, modify or remove the cover of  
the traction battery.  
Charging system  
(Electric)  
400 V electrical system  
The electric drive system, which operates at a  
voltage of approximately 400 V, is identified by  
orange cables and its components are marked  
with this symbol:  
– Never work with cutting and forming  
tools or heat sources near high voltage  
components and cables.  
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.  
In case of low level of fluid in the cooling  
tank, the refilling shall only be performed in a  
qualified and trained workshop to verify that  
the leakage is not in the traction battery.  
Any intervention on the high voltage system  
must be carried out by qualified persons in  
workshops qualified and approved to carry  
out this type of work.  
An electric vehicle’s power train can  
become hot during use and after  
switching off the ignition.  
Comply with the warning messages shown  
on the labels, particularly inside the charging  
flap.  
The misfuel prevention device does not  
prevent filling with a jerrycan, regardless  
of the fuel type.  
High voltage system voltage is  
dangerous and can cause burns or other  
injuries or even fatal electric shock.  
Since damage to high voltage components is  
not visible, CITROËN recommends that you:  
– Never touch the components, damaged  
or not, and never let your jewelry or other  
metallic objects come into contact with these  
components.  
Damage to the vehicle or the traction battery  
could result in the leakage of toxic gases or  
fluids either immediately or later. CITROËN  
recommends that you:  
– Always inform the fire and emergency  
services in the event of an incident, warning  
that the vehicle is equipped with a traction  
battery.  
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 CITROËN dealer if the vehicle is  
suitable for the distribution equipment of the  
countries visited.  
– Never touch the liquids leaking from the  
traction battery.
