Air filter and passenger compartment filter
Particle filter system (Diesel)
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
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 occa-
sionally notice water vapour being
emitted from the exhaust when ac-
celerating. This is of no consequence
to the running of the vehicle or to the
environment.
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
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 cabin filter may have an
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Battery
The battery does not require
any maintenance.
However, check that the
terminals are clean and
correctly tightened, par-
ticularly in summer and
winter.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble 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).
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.
Oil filter
Replace the oil filter each
time the engine oil is
changed.
Refer to the Maintenance and Warranty
Guide for details of the replacement in-
terval for this component.

If this alert persists, consult a
