CHECKS
Levels and checks
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the maintenance and warranty
guide which correspond to your vehicle's
engine.
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.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, contact a
CITROËN dealer or a qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is strictly
prohibited.
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.

Levels and checks
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 / Regeneration 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 to 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.)

TECHNICAL DATA
Diesel engines
Quality of the fuel used for Diesel engines
The Diesel engines are perfectly compatible with biofuels which conform \
to current and future European standards (Diesel fuel which
complies with standard EN 590 mixed with a biofuel which complies with s\
tandard EN 14214) available at the pumps (containing up to
5% Fatty Acid Methyl Ester).
The B30 biofuel can be used in certain Diesel engines; however, this use is subject to strict application of the special servicing con\
ditions
given in the maintenance and warranty guide. Contact a CITROËN dealer\
or a qualified workshop.
The use of any other type of (bio)fuel (vegetable or animal oils, pur\
e or diluted, domestic fuel...) is strictly prohibited (risk of damage to the
engine and fuel system). ENGINES AND GEARBOXES
