Topping up the

cooling system

The coolant level

should be between

the

MIN marks on the

MAX

and

header tank.

Top up the level. If you have to

add more than 1 litre, you should

have the cooling system checked

by CITROËN.

Make sure that the cap is on

correctly

Note: The necessity to top up

frequently would indicate a mal-

function that should be checked at

the earliest opportunity.

Radiator - coolant

Adding engine oil

The coolant must only be checked

or topped up if the power unit is

cold.

Remove the dipstick before top-

ping up.

Check the level after ﬁlling.

It should never exceed the

maximum mark.

Screw on the cap before closing

the bonnet.

Quality: See “Maintenance Guide”.

Note: on vehicles equipped with a

particle ﬁlter, the cooling fan may

operate for some ten minutes after

the engine has stopped.

Engine hot

Release the protection cover.

Wait 15 minutes or until the tem-

perature is below 100 degrees C.

Usingaclothtoprotectyourhands,

slowly slacken the ﬁller cap as

far as the safety catch. Allow the

pressure to reduce before remov-

ing ﬁller cap.

Windscreen and rear screen

washer ﬂuid

For best results as well as for

your safety, use only CITROËN

approved products which protect

at temperatures as low as -25°C

to -30°C.

It is essential to have sufﬁcient

screen wash ﬂuid if your vehicle is

equipped with Xenon headlamps.

Brake ﬂuid

The synthetic ﬂuid not only gives protection against corrosion but also

ensures correct functioning of the braking system in all environmental con-

ditions, therefore you should only use the synthetic product recommended

by the CITROËN network. (this ﬂuid must be replaced every two years).

These important requirements are detailed in your vehicle’s maintenance

Guide.

Quality: See “maintenance Guide”.

Priming the fuel system

In the event of running out of fuel:

- After ﬁlling (5 litres minimum),

operate the manual priming

pump until some resistance is

felt.

- Operate the starter motor while

depressing the accelerator pedal

slightly until the engine starts.

If the engine fails to start at the ﬁrst

attempt, wait 15 seconds before

trying again.

If the engine fails to start after

several attempts, repeat the pro-

cedure from the beginning.

When the engine is idling, accel-

erate slightly to complete the

bleeding of the circuit.

Engine HDi 138

Detach the protection cover to

access the priming pump.

It is essential to proceed strictly following the sequence

indicated.

Check that the emergency battery is correctly charged

up (12 volts). If you are using the battery on another

vehicle, stop the engine of the assisting vehicle. The

two vehicles must not come into direct contact with

each other.

Connect the cables in the order indicated in the dia-

gram. Make sure that the clamps are properly secured

(risk of sparks).

C

Start the engine of the assisted vehicle.

Note: For any repair necessitating a disconnection

of the battery, it is essential to wait three minutes

after switching off the ignition and to avoid any action

that could prevent the vehicle’s electrical circuit from

changing to standby mode (such as opening and clos-

ing doors, using the remote control etc.).

V

Start the engine of the assisting vehicle. Let the engine

run for about a minute at a slightly accelerated speed.

Advice

Replace it with a battery of the

same type (voltage, amp rating).

Do not touch the cable clamps

Never apply a ﬂame or create sparks close to the battery (explo-

sive gas). The battery contains diluted sulphuric acid which is

highly corrosive.

during the procedure.

Do not lean over the batteries.

Disconnect the cables in the

reverse order to connection,

ensuring that they do not touch

each other.

If ever you are handling the battery, protect your eyes and face.

In the event of any contact with the skin, rinse immediately with

copious amounts of fresh water.

B AT T E R Y

Starting the engine for the ﬁrst time after disconnecting and

connecting the battery:

- Turn the ignition key.

- Wait approx. one minute before actioning the starter, so as to allow the

electronic systems to reinitialise.

After the battery has been disconnected for a long period, it may be necessary to re-initialise the following func-

tions:

V

- Anti-pinch and sequential operation on the electric windows.

- Parameters of the multifunction display (date, time, language, units of distance and temperature).

- Radio stations.

- Navigation reception.

- Synchronisation of remote control.

- Central locking.

Certain adjustments will be cancelled: it is necessary to make them again.

WARNING: If disconnecting the battery, check that the colour navigation reader located in the glovebox

has ﬁnished its recording of information on switching off ignition: the warning lamp should have gone

out.

Fuse box

There are two fuse boxes, one below the dashboard and one under

the bonnet.

Fuses under the dashboard

To access the fuses below the dashboard, pull back the access

cover, undo the screws a quarter turn and tilt the whole unit.

Replacing a fuse

Before replacing a fuse, it is essential to ﬁnd the cause of the inci-

dent and to rectify it. The fuse identiﬁcation numbers are indicated

inside the fuse box.

V

Replace a blown fuse with one of the same rating

(the same colour)

Use the special pliers A stowed on the cover close to the fuse-

boxes, this includes a compartment for replacement fuses.
