12 V battery
The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly 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.
Particle filter system (Diesel)
Complementary to the catalytic con-
verter, this fi lter makes an active
contribution to the preservation of air
quality by trapping unburnt pollutant
particles. Black exhaust fumes are
thus no longer emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of blockage, a mes-
sage appears in the instrument
panel screen, accompanied by an
audible signal and illumination of
the service warning lamp.
This alert tells you that the par-
ticle fi lter is approaching satura-
tion (in conditions of urban driving
of exceptionally long duration: low
speeds, traffi c jams etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, contact a CITROËN
dealer or a qualifi ed workshop.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and specifi -
cation. The involvement of a CITROËN
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery.
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 qualifi ed
workshop.
Air filter and passenger compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
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 .
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesirable
odours.
Replace the oil fi lter each
time the engine oil is
changed.
Oil filter
Refer to the servicing booklet for de-
tails of the replacement interval for
this component.
