CHECKS
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and in
relation to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not
require any maintenance.
However, check that the
terminals are clean and
correctly tightened, parti-
cularly in summer and winter.
When carrying out work on the bat-
t e r y , r e f e r t o t h e " P r a c t i c a l i n f o r -
mation" section for details of the
precautions to be taken before dis-
connecting 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 l t e r m a y h a v e a n a d v e r s e e f f e c t o n

tioning system and generate unde-
sirable odours.
Oil filter

time the engine oil is
changed. Particulate filter system
(Diesel)
Complementary to the catalytic con-
v e r t e r , t h i s fi l t e r m a k e s a n a c t i v e
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 accelerat-
ing. 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 l t e r i s s t a r t i n g t o fi l l u p ( i n c o n d i t i o n s

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.
