until the warning lamp goes off.
fixed, accompanied by an audible signal and and a message that the
particle emissions filter additive level is too low.
This indicates the low level of the additive reser voir. Have the reser voir topped up as soon as possible by a CITROËN dealer or a qualified workshop.

This information is displayed for a few seconds when the ignition is switched on, at the same time as the ser vice information.
Engine oil level indicator
The vehicle must be on level ground and the engine must have been off for more than 30 minutes for this level check to be accurate.
Oil level correct
Oil level incorrect
This is indicated by the flashing of "OIL" or the display of a specific message in the instrument
panel, coupled with the ser vice warning lamp and accompanied by an audible signal. If the low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid damage to the engine.

Quality of the fuel used
for petrol engines
The petrol engines are per fectly compatible with E10 type petrol biofuels (containing 10 % ethanol), conforming to European standards EN 228 and EN 15376. 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 conver ter, a device which helps to reduce 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.
