Quality of the fuel used for
Diesel engines

The Diesel engines are per fectly compatible
with biofuels which conform to current andfuture 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).
The B30 biofuel can be used in cer tain Diesel engines; however, this use is subject to strict
application of the special ser vicing 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).


















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 comesinto contact with the flap. The system remains closed and prevents filling. Do not persist but introduce a Diesel typefiller nozzle.
Operation
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 themisfuel prevention device and pour slowly.
