CHECKS
Unless otherwise indicated, check
these components in accordance
with the Warranty and Maintenance
Record and according 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, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
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 Warranty and
Maintenance Record 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" section).

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 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 clogging, a message
appears on the multifunction screen,
accompanied by an audible signal
and lighting of the service warning
lamp.
This alert tells you that the particle

the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.

For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
i t y a n d s p e c i fi c a t i o n s .
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
f e r s v e r y s p e c i fi c p r o d u c t s .
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
