Levels

These regular maintenance operations
will keep your vehicle in good working

order. Ask for advice from a CITROËN
dealer or refer to the servicing booklet
provided in the handbook pack.

LEVELS

Oil level

Check the level regularly and top up
between changes. The maximum oil
consumption is 0.5 litre per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick.

Dipstick

There are two marks on the
dipstick:

A = maximum
If you fill past this mark,
contact a CITROËN dealer.

B = minimum
Never allow the level to fall
below this mark.

To preserve the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.

Oil change

Brake fluid level

The brake fluid must be changed at
the specified interval, as given in the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which meets the DOT4
standard.
The level must be between the MIN and
MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a fault which must be checked by a
CITROËN dealer as soon as possible.

Warning lamps

Checking by means of the warning
lamps in the instrument panel is
described in chapter 1, refer to the
"Instruments and controls" section.

This must be carried out at the specified
interval and the viscosity grade of the oil
selected must fulfil the requirements of the
manufacturer's servicing schedule. Ask for
advice from a CITROËN dealer.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Refit the filler cap before closing the bonnet.

Levels

Engine coolant level

Only use the fluid 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.

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
5.5 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 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.

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 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.

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.

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.

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
is required when replacing or disconnecting
the battery.
Failure to observe this recommendation may
cause premature wear of the battery.

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
fi lter 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 fi lter, fi tted 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.

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 fi lter, it is
recommended that you do not park the vehicle
over infl ammable materials (grass, dry leaves,

pine needles, ...) so as to avoid any risk of fi re.
