CHECKS
Unless otherwise indicated, check
these components in accordance with
the servicing booklet and according to
your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed workshop.
Battery
The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
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.
Air filter and passenger compartment filter
Refer to the servicing booklet
for details of the replacement
intervals for these compo-
nents.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the servicing booklet
for details of the replacement
interval for this component.
Particle emission filter (Diesel)
According to your version of instrument
panel, the start of saturation of the par-
ticle emissions fi lter is indicated by:
- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that there is a risk of blockage
of the particle emissions fi lter,
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery.
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).
A clogged passenger compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.
As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
On a new vehicle, the fi rst opera-
tions of regeneration of the particle
emissions fi lter may be accom-
panied by the smell of "burning",
which is perfectly normal.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. or
-
temporary illumination of
the service warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of
the particle emissions fi lter.

Electric parking brake
This system does not require any
routine servicing. However, in
the event of a problem, have the
system checked by a CITROËN
dealer or a qualifi ed workshop.
For more information, see "Driving - Electric parking brake - § Operating faults".
Brake pads
Brake disc wear
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.
In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.
Manual parking brake
For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. Brake wear depends on the
style of driving, particularly in
the case of vehicles 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 system, a drop
in the brake fl uid level indicates that the
brake pads are worn.

black cable to the negative terminal
(-) of the slave battery B
.
)
Connect the other end of the green
or black cable to the earth point C
on the broken down vehicle.
