E85 type fuels (containing up to 85 % ethanol) are reser ved 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. For Brazil only, special vehicles are marketed to run on fuels containing up to 100 % ethanol (E100 type).
Quality of the fuel used
for Diesel engines
The Diesel engines are per fectly 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). 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).
The petrol or Diesel engine of your vehicle is fitted with a catalytic converter, a device which helps to redu ce the level of harmful emissions in the exhaust gases .For petrol engines, the use of unleaded fuel is compulsor y. The filler neck is narrower, admitting unleaded petrol nozzles only.
Fuel supply cut-off
Your vehicle is equipped with a safety device which cuts off the fuel supply in the event of a collision.
If you have put in the wrong fuel for your vehicle, you must have have the tank drained and refilled with the correct fuel before you star t the engine.

Access
Misfuel prevention
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. Do not persist but introduce a Diesel type filler nozzle.
Operation
It is still possible to use a fuel can to fill the reser voir. 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.
This equipment will become available during the year.
