CHECKS


Bleeding water from
the Diesel filter

If this warning lamp comes
on, you must bleed the filter;
otherwise bleed the filter
regularly, every time the engine is
changed.
To remove the water, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Operate until all of
the water has flowed out. Then tighten the
bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires specialist knowledge, which
all CITROËN dealers have.


Battery

At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.


Air filter and passenger compartment
filter
A blocked passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the "Under the
bonnet" section of chapter 7.


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 brake pad wear,
even between services.
Unless there is a leak on the system, a drop
in the brake fluid level indicates that the
brake pads are worn.


Brake disc/drum wear

For all information on checking the brake
disc/drum wear, 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.


Oil filter

Change the filter regularly, in accordance
with the servicing schedule.





The presence of this label, in particular with
the Stop & Start system, indicates the use
of a specific 12 V lead-acid battery with
special technology and specification, for
which the involvement of a CITROËN dealer
or a qualified workshop is required when
replacing or disconnecting the battery.
Failure to observe this recommendation may
shorten the life of the battery.

QUICK HELP



Checks








Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for the details of the level checking
interval for this component.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet 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.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited.






Particle filter system (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).
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.

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.








Electronic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for details of
the checking interval for this component.
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.
