Practical information -> Refuelling for Your Citroen C4 SUV Third Generation (2020-2025)

Practical information  
fuels could prevent the engine from operating  
correctly. In these temperature conditions, use  
winter-type Diesel fuel and keep the fuel tank  
more than 50 % full.  
signal are repeated with increasing frequency as  
the fuel level drops towards 0.  
You must refuel as soon as possible to avoid  
running out of fuel.  
Compatibility of fuels  
Petrol fuels conforming to the EN228 standard  
containing up to 5% and 10% ethanol  
respectively.  
At temperatures below -15 °C (+5 °F) to avoid  
problems starting, it is best to park the vehicle  
under shelter (heated garage).  
For more information on Running out of fuel  
(Diesel), refer to the corresponding section.  
A small arrow by the warning lamp  
indicates which side of the vehicle the  
fuel filler flap is located on.  
Travelling abroad  
Certain fuels could damage your vehicle’s  
engine.  
In certain countries, the use of a particular  
fuel may be required (specific octane rating,  
specific trade name, etc.) to ensure correct  
operation of the engine.  
Diesel fuels conforming to the EN590, EN16734  
and EN16709 standards and containing up to  
7%, 10%, 20% and 30% fatty acid methyl ester  
respectively. The use of B20 or B30 fuels, even  
occasionally, imposes special maintenance  
conditions referred to as "Arduous conditions".  
Stop & Start  
Never refuel with the engine in STOP  
mode; you must switch off the ignition.  
For all additional information, consult a dealer.  
Refuelling  
When refuelling, at least 5 litres must be added  
in order to be registered by the fuel gauge.  
Opening the filler cap may create a noise caused  
by an inrush of air. This vacuum is normal,  
caused by the sealing of the fuel system.  
To refuel in complete safety:  
Paraffinic Diesel fuel conforming to the EN15940  
standard.  
Refuelling  
Fuel tank capacity: approximately 50 litres.  
Reserve level: approximately 6 litres.  
The use of any other type of (bio) fuel  
(vegetable or animal oils, pure or diluted,  
domestic fuel, etc.) is strictly prohibited (risk  
of damage to the engine and fuel system).  
Low fuel level  
Always switch off the engine.  
When the low fuel level is reached, this  
warning lamp lights up on the instrument  
panel, accompanied by the display of a message  
and an audible signal. When it first comes on,  
about 6 litres of fuel remain.  
The only fuel additives authorised for use  
are those that meet the B715001 (petrol)  
or B715000 (Diesel) standards.  
Until sufficient fuel is added, this warning lamp  
appears every time the ignition is switched on,  
accompanied by the message and the audible  
signal. When driving, this message and audible

Practical information  
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.

As Diesel fuel pump nozzles may be  
different in other countries, the presence  
of the misfuel prevention device may make  
refuelling impossible.  
The filler neck is narrower, admitting unleaded  
petrol nozzles only.  
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.  
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.  
Charging system  
(Electric)  
► With the vehicle unlocked, press the rear-  
central part of the filler flap to open it.  
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).  
► Turn the filler cap to the left, remove it and  
place it on its support (on the filler flap).  
► Insert the filler nozzle and push it in as far as  
possible before starting to refuel (to minimise the  
risk of splashing).  
Operation  
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:  
Do not continue after the nozzle’s third cut-  
out. Doing so may cause malfunctions.  
► Put the filler cap back in place and turn it to  
the right.  
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.  
► Close the fuel filler flap.  
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.  
Do not persist but introduce a Diesel type  
filler nozzle.  
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.  
The use of a fuel jerrycan to fill the tank  
remains possible.
