Failure to observe this recommen-

CHECKS
Particle filter system (Diesel)
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualified
workshop.
Complementary to the catalytic
converter, this filter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving
at very low speeds, you may oc-
casionally notice water vapour be-
ing emitted from the exhaust when
accelerating. This is of no conse-
quence to the running of the vehicle
or to the environment.
Air filter and passenger
compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
12 V battery
The battery does not re-
quire any maintenance.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), replace them twice as often
if necessary (refer to the "Engines"
section).
A clogged passenger compartment
filter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical information"
section for details of the precautions
to be taken before disconnecting the
battery and following its reconnection.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audible
signal and lighting of the service
warning lamp.
This alert tells you that the particle
filter is starting to fill up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffic jams etc.)
To regenerate the filter, it is advised
to drive as soon as possible, when
traffic conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least five minutes (until
the alert message disappears).
Oil filter
Replace the oil filter each
time the engine oil is
changed.
X
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specific 12 V
lead-acid battery with special tech-
nology and specification, for which
the involvement of a CITROËN
dealer or a qualified workshop is
required when replacing or discon-
necting the battery.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.
If this alert persists, consult a
CITROËN dealer or a qualified
workshop.
