In addition to the catalytic converter, this fi lter contributes actively to the preserving of air quality, by collecting the polluting particles that have not been burnt off. Black exhaust fumes are thus eliminated.
Simultaneous lighting of the SERVICE and depollution system warning lamps indicates an increased risk of clogging.
Contact a CITROËN dealer as soon as possible.
DIESEL ADDITIVE LEVEL
If the additive level is low, it is necessary to top up the additive level.
Contact a CITROËN dealer as soon as possible.
CLOGGING OF THE PARTICLE FILTER
Clogging is caused by the particle fi lter starting to be satu rated (owing to exceptionally long periods spent driving in urban conditions: low speeds, traffi c jams, et c.).
In order to regenerate the fi lter you are advised to drive as soon as possible, when traffi c conditions allow, at a speed of 60 km/h (37 mph) or more for at least 5 minutes. If the probl em persists, contact a CITROËN dealer.In order to regenerate the fi lter you are advised to drive as soon as possible, when traffi c conditions allow, at a speed In order to regenerate the fi lter you are advised to drive as soon as possible, when traffi c conditions allow, at a speed
Note: If the vehicle has been running for long periods at very low speeds or at idle, vapour emissions may be seen coming from the exhaust under acceleration. These have no consequ ences for the running of the vehicle or for the environment.
