Particle filter (1.3 HDi 75)
an addition to the catalytic converter, this
filter 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.
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
control unit manages the automatic
periodic elimination of the soot particles
(regeneration).
the regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature - which does not affect the
operation of the vehicle or the environment.
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. Saturation / Regeneration
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
This alert tells you that the
particle filter is starting to fill up (in
conditions of urban driving of exceptionally
long duration: low speeds, traffic jams etc.)
To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears). Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have it checked by a CITROËN dealer or a
qualified workshop.
Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles,
...) so as to avoid
any risk of fire. If possible, avoid switching off the
engine before the end of regeneration
of the filter; repeated interruptions could
cause premature deterioration of the
engine oil. It is not recommended to end
regeneration of the filter with the vehicle
stationary.

batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance with the
law and must not, in any circumstances be
discarded with household waste.
Take used batteries to an authorised waste
disposal site.
It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month. To do
this on models with Stop & Start:
-

press the release button

E
to
disconnect connector F ,
-

disconnect connector

of check
sensor G.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITR
o
Ë
n
dealer or
a qualified workshop is essential when
replacing or disconnecting the battery.
Failure to observe this recommendation may
cause premature wear of the battery.
After refitting the battery by a
CITR
o
Ë
n
dealer or a qualified
workshop, the Stop & Start system will
only be active after a continuous period of
immobilisation of the vehicle, a period which
depends on the climatic conditions and the
state of charge of the battery (up to about
8 hours). Before charging
The charging operation must be carried
out in a ventilated area away from naked
flames or any possible sources of sparks to
eliminate the risks of explosion and fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
Before disconnecting
n

ever disconnect a terminal when the
engine is running.
Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Close the windows and doors before
disconnecting the battery. After reconnecting
a

fter every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If difficulties are
experienced after this, contact a CITR o Ë n

dealer or a qualified workshop.
If the battery has been disconnected

for some time, it may be necessary to
reinitialise the following functions:
-

the display screen settings (date, time,

language, distance and temperature
units),
-

the radio stations,
-


the central locking.
Some settings are cleared and must be

reprogrammed. Contact a CITROËN dealer
or a qualified workshop.
Never remove the check sensor G
from the
negative battery terminal H , except when
replacing the battery.
