Complementary to the catalytic converter, this filter makes an active contribution to the preservation of air quality
by the retaining of the unburnt pollutant particles. Black exhaust fumes are thus no longer emitted.
Clogging of the particle filter
This alert tells you that the particle filter is starting to fill up (in conditions of urban driving of exceptionally long
duration: low speeds, traffic jams etc.)
In order to regenerate the filter, you are advised to drive as soon as possible, when the traffic conditions permit, at
a speed of 60 km/h (around 40 mph) or more for at least 5 minutes.
If this alert persists, consult a CITROËN dealer.
Observation: After prolonged idling or driving at very low speeds, you may occasionally notice water vapour being
emitted from the exhaust when accelerating. This is of no consequence to the running of the vehicle or to the
environment.
Diesel fuel additive level
If the additive level is low, it is necessary to top up the additive. Contact a CITROËN dealer as soon as possible.
