Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reservoir.
If this warning lamp comes on, the
filter must be bled to remove water.
Y
ou can also bleed the fuel filter
regularly, every time the engine oil
is changed.
Bleeding water from the filter
-
Connect a transparent pipe to the head
of the bleed screw 1 .
-
Place the other end of the transparent
pipe in a recipient.
-
Slacken the bleed screw

technology. All work must be done by
personnel that have had special training,
which can be ensured by going to a
CITROËN dealer or a qualified workshop. -

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 the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation /
r
egeneration
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.
Particle filter system (diesel)
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.
Operation
This filter, fitted in the exhaust system,
accumulates particles of soot. The engine
management unit controls 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. 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).
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.
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.)
