CHECKS
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and in re-
lation to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that
the terminals are clean
and correctly tightened,
particularly in summer and winter.
When carrying out work on the
battery, refer to the "Practical
information" section for details of
the precautions to be taken before
disconnecting the battery and
following its reconnection.
Air filter and passenger compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the
environment (e.g. dusty atmosphere)
and the use of the vehicle (e.g. city
driving), replace them twice as
often if necessary (refer to the
"Engines" paragraph).
A clogged passenger compartment
fi lter may have an adverse effect
on the performance of the air
conditioning system and generate
undesirable odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particulate filter system
(Diesel)
Complementary to the catalytic
converter, this fi lter 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.
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.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by a sound
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
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.
Refer to the servicing booklet for
details of the replacement interval
for this component.
