Levels


Engine coolant level

Only use the fl uid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine cooling fan. As this fan
can operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine has
stopped before carrying out any work.

Topping up
The level must be between the MIN
and
MAX
marks on the header tank. If more than
1 litre of fluid is required to top up the level,
have the system checked by a CITROËN
dealer or a qualified workshop.



Power steering fluid level

The vehicle must be parked on level ground
with the engine cold. Unscrew the cap with
integral gauge and check the level which
must be between the MIN
and MAX
marks.


Screenwash fluid level

For optimum cleaning and to avoid freezing,
topping up or replacement of this fluid
should never be with plain water; we
recommend the use of products available
from CITROËN dealers.
Capacity of the reservoir: approximately
3 litres. Slacken the cap by two turns to release the
pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
CITROËN dealer or a qualified workshop as
soon as possible.

Used products

Avoid prolonged contact of used oil with the
skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground, but
into the containers provided for this purpose
at CITROËN dealers (France) or at an
authorised waste disposal site.

QUICK HELP



Checks


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
oil 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 maintenance and warranty guide.
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 type 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.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery.

Checks







Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and warranty
guide 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 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.
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.






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 maintenance and warranty
guide 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.
