Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine the minimum speed is 36 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
on a n

ew vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
