If you are filling your tank to the top, do not 
persist after the third cut- off; this could 
cause your vehicle to malfunction.
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, the use of unleaded fuel 
is compulsory.
The filler neck is narrower, admitting unleaded 
petrol nozzles only.

Fuel used for petrol engines
The petrol engines are compatible with 
E10 bio-petrol (containing 10 % ethanol), 
conforming to European standards EN 228 and 
EN 15376.
E85 type fuels (containing up to 85 % ethanol) 
are reserved exclusively for vehicles marketed 
for the use of this type of fuel (BioFlex 
vehicles). The quality of the ethanol must 
comply with European standard EN 15293.
Fuel used for diesel 
engines
The Diesel engines are compatible with 
biofuels which conform to current and future 
European standards (Diesel fuel which 
complies with standard EN 590 mixed with 
a biofuel which complies with standard 
EN
  14214) available at the pumps (containing 
up to 7 % Fatty Acid Methyl Ester).
B30 biofuel can be used in certain Diesel 
engines. However, this use, even occasional, 
requires strict application of the special 
servicing conditions. Contact a CITROËN 
dealer or a qualified workshop.
The use of any other type of (bio)fuel 
(vegetable or animal oils, pure or diluted, 
domestic fuel...) is strictly prohibited (risk of 
damage to the engine and fuel system).

Travelling abroad
As Diesel fuel pump nozzles may 
be different in other countries, the 
presence of the misfuel prevention 
device may make refuelling impossible.
Not all Diesel vehicles are fitted with 
misfuel protection, so 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 
intend to travel.
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.
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 your Diesel vehicle, it comes 
into contact with the flap. The system remains 
closed and prevents filling.
