Diesel particulate filter system
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
The SERVICE warning lamp and a message
in the instrument panel are displayed indicating that the particulate filter is
starting to become clogged (exceptionally prolonged urban driving conditions: reduced
speed, traffic congestion…).
To regenerate the filter, you are advised to drive, as soon as traffic conditions permit, at a speed of 60 km/h (40 mph) or more for at least 5 minutes (until the warning message disappears).
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, a
message appears in the multifunction screen, accompanied by an audible signal and
illumination of the SERVICE warning lamp: it is necessary to have the additive level
topped up. Contact a CITROËN dealer as soon as possible.
