FUEL CIRCUIT DISARMED

In a serious collision, a mechanism
automatically prevents fuel from
reaching the engine.
The fl ashing of this warning
light is accompanied by a
message on the display.
DIESEL REPRIMING
PUMP



If you should run out of fuel, it is
necessary to re-prime the circuit:


- fi ll the fuel tank with at least fi ve
litres of diesel,

- squeeze and release the manual
re-priming pump, under the bonnet
under the protective cover, until fuel
appears in the transparent pipe,

- operate the starter until the engine
starts. Check that there is no odour or
leakage of fuel outside the vehicle and
re-establish the fuel supply:


- switch off the ignition
(STOP position).

- remove the key.

- put the key back in the ignition.

- switch on the ignition and start.













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 standard
EN 14214) available at the pumps
(containing up to 7 % 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 conditions. Consult a
CITROËN dealer.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or
diluted, domestic fuel...) is strictly
prohibited (risk of damage to the
engine and fuel system).

These regular maintenance
operations will keep your vehicle
in good running order. Consult the
instructions at CITROËN dealerships
or in the servicing booklet enclosed in
the handbook pack. To maintain the reliability of engines
and emission control systems, the use
of additives in engine oil is prohibited.



Oil change

It is imperative that this is carried out at
the intervals specifi ed and the viscosity
grade of the oil selected must fulfi l the
requirements in accordance with the
manufacturer's servicing schedule.
Consult the instructions at CITROËN
dealerships.
Remove the dipstick before fi lling.
Check the level after fi lling (never
exceed the max mark).
Screw the cap back onto the sump
before closing the bonnet.
LEVELS

If you have to remove/refi t the
engine style cover, handle it with
care to avoid damaging the fi xing
clips.

Dipstick


Warning lights
Oil level

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

Viscosity selection
In all cases, the oil selected must meet
the manufacturer's requirements.
Checking by means of the
warning lights on the instrument
panel is described in chapter 2,
"Instruments and controls" section.


Changing the brake fluid

The brake fl uid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fl uids recommended by the
manufacturer, which fulfi l DOT4
standards.
The level must be between the MIN
and MAX marks on the reservoir.
If fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.
There are two marks
on the dipstick:

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

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

Levels


Cooling system

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 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.
Slacken the cap by 1/4 of a turn 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 fl uid has to be added frequently,
this indicates a failure which must be
checked by a CITROËN dealer as
soon as possible.

Power steering fluid level

The vehicle must be parked on level
ground with the engine cold. Unscrew
the cap integrated with the gauge and
check the level which must be between
the MIN and MAX marks. During regeneration of the particle
emission fi lter, relay noise may be
heard under the fascia.
If the message is still displayed and
the service warning light remains on,
contact a CITROËN dealer.

Diesel additive level (Diesel with
particle emission filter)
When this occurs with the engine running,
this is due to the start of saturation of
the particle emission fi lter (exceptionally
prolonged urban driving conditions: low
speed, long traffi c jams, ...).
In order to regenerate the fi lter, you are
advised to drive at a speed of more than
40 mph (60 km/h) as soon as possible,
when traffi c conditions permit, for at
least fi ve minutes (until the message
disappears and the service warning light
is switched off).
Topping up
The level must be between the MIN
and MAX marks on the expansion
bottle. If more than 1 litre of fl uid is
required to top up the level, have the
system checked by a CITROËN dealer.



Windscreen wash and headlamp
wash level
For best quality cleaning and for your
safety, we would advise that you use
products of the CITROËN range.
To avoid ice forming, do not use water.
Topping up
It is imperative that this additive is
topped up by a CITROËN dealer
without delay.



Used oil

Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
Do not dispose of used oil, brake
fl uid or coolant into drains or onto
the ground but into the containers
dedicated to this use at CITROËN
dealerships. The minimum level of this
additive is indicated by
lighting of the service warning
light, accompanied by an
audible signal and a message
on the display.

CHECKS

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
specifi cation.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers
specifi c products.
In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is
strictly prohibited.

Oil filter

Change the fi lter regularly, in
accordance with the servicing
schedule. Refer to the servicing booklet to
fi nd out the replacement interval
for these components.
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 6.


Particle emission filter (Diesel)

It is imperative that particle emission
fi lter maintenance is carried out by a
CITROËN dealer.
On acceleration after the vehicle has
been running for a prolonged period
at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust. This water vapour does not
have any adverse effect on vehicle
handling or the environment.

Battery

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


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.
Unless there is a leak on the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.


Brake disc/drum wear status

For any information relating to
checking the brake disc/drum wear
status, contact a CITROËN dealer.


Handbrake

Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
CITROËN dealer.


Carbon filter and passenger
compartment filter
The carbon fi lter permits continuous
and effective fi ltering of dust.
If the passenger compartment fi lter
becomes clogged, this may reduce
the performance of the air conditioning
system and generate unpleasant
odours.
We recommend the use of a combined
passenger compartment fi lter. By
means of its second special active
fi lter, it contributes to the purifi cation
of the air breathed by the occupants
and to the cleanness of the passenger
compartment (reduction of allergic
symptoms, unpleasant odours and
greasy deposits).

Manual gearbox

Have the level checked in accordance with
the manufacturer's servicing schedule.

An incorrect waveband is selected.
Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on which thestations are stored.

The traffi c announcement(TA) is displayed. I donot receive any traffi c information.
The radio station is not part of the regional traffi c information network.
Tune to a radio station which broadcasts traffi c information.

The quality of receptionof the radio station listened to graduallydeteriorates or the stored stations do not function(no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used by the station listenedto or there is no transmitter in the geographical area through which the vehicle is travelling.
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode. This phenomenon is normal and does not indicate a failure of the audio equipment.
The aerial is absent or has been damaged (for example when goingthrough a car wash or into an underground car park).
Have the aerial checked by a CITROËN dealer.
Sound cut-outs of 1 to2 seconds in radio mode.During this brief sound cut-out, the RDS searches for any frequency permitting better reception of the station.
Deactivate the RDS function if the phenomenon is too frequent and always on the same route.

With the engine off, the audio equipment switches off after a few minutes of use.
When the engine is switched off, the audio equipment operating timedepends on the battery charge.
The switch-off is normal: the audio equipment switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the batterycharge.
The message "the audio system is overheated" appears on the display.
In order to protect the installation if the surrounding temperature is toohigh, the audio equipment switches to an automatic thermal protectionmode leading to a reduction of the volume or stopping of the playing of the CD.
Switch the audio system off for a few minutes toallow the system to cool.
