The battery does not re-
quire any maintenance.
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.
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN

required when replacing or discon-
necting the battery.

Particle filter system (Diesel)
Complementary to
converter, this fi lter 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.
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
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.)
To regenerate the fi lter, it is advised
is
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, consult a
CITROËN dealer or a qualifi ed
workshop.
