RUNNING OUT OF FUEL
(DIESEL)

HDi 138 engine

Detach the protective cover for access
to the priming pump.

HDi 110 engine

Detach the protective cover for access
to the priming pump.

Priming the fuel circuit

In the event of running out of fuel:


after fi lling (minimum 5 litres),

squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,

 then operate the starter, gently

pressing the accelerator until the
engine starts.

If the engine fails to start at the fi rst

attempt, wait 15 seconds before
trying again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.

HDi engines are of a highly
technical nature.
All maintenance and re-

pairs require specifi c qualifi cations

which only your CITROËN dealer
can guarantee.

CHECKING LEVELS

Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the

corresponding system checked by a
CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).

Oil level

Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.

Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufacturer's
recommendations.

Brake fluid level

Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This fl uid must be changed regu-

larly. Fluid which has been used for
too long may cause a loss of braking

effi ciency.

Fluid specifi cation

The brake fl uid must conform to the

manufacturer's

recommendations

and fulfi l the DOT4 standards.

Coolant level

Coolant change
The coolant does not have to be
changed.

Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.

The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.

The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Check this level also between each
scheduled service and before long
journeys.

The brake fl uid level should

be close to the "MAX" mark.
If it is not, check the brake
pad wear.

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm,

the temperature of the coolant is regu-
lated by the fan. This can operate with
the ignition off.

On vehicles which are fi tted with

a particle emission fi lter, the fan

may operate after the vehicle has

been switched off, even if the en-

gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, un-
screw the cap by two turns to allow
the pressure to drop. When the pres-
sure has dropped, remove the cap
and top up the level.

In order to maintain the re-
liability of the engine and
emission control system,

the use of additives in the engine
oil is prohibited.

Screenwash and headlamp
wash fluid

Fluid specifi cation
For optimum cleaning and to avoid

freezing, this fl uid must not be topped

up or replaced with plain water.
Reservoir capacities:
-

screenwash: approximately 3 litres,

-

screenwash

and

headlamp

wash: approximately 6 litres.

Diesel additive level
(Diesel engine with particle
emission filter)

A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.

Topping up
This additive must be topped up by
a CITROËN dealer without delay.

Used products

Avoid prolonged contact of

used oil or fl uids with the

skin.

Most of these fl uids are harmful to

health or indeed very corrosive.

Do not discard used oil or

fl uids into sewers or onto

the ground.

Take used oil to a CITROËN dealer
(France) or an authorised waste
disposal site.

In the case of vehicles fi tted

with headlamp washers, the

minimum level of this fl uid is

indicated by an audible signal

and a message on the multifunction
screen.
Top up the level when you next stop
the vehicle.

CHECKS

Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.

Battery

The battery does not require
any maintenance.
However, check that the
terminals are clean and
correctly tightened, par-
ticularly in summer and
winter.

When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.

Air filter and passenger compartment filter

Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.

Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" paragraph).
A clogged cabin fi lter may have an

adverse effect on the performance
of the air conditioning system and
generate undesirable odours.

Oil filter

Replace the oil fi lter each

time the engine oil is
changed.

Particle filter system (Diesel)

Complementary to the catalytic

converter, this fi lter makes an ac-

tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at
very low speeds, you may occa-
sionally notice water vapour being
emitted from the exhaust when ac-
celerating. This is of no consequence
to the running of the vehicle or to the
environment.

If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the service
warning lamp.
This alert tells you that the particle

fi lter is starting to fi ll up (in condi-

tions of urban driving of excep-
tionally long duration: low speeds,

traffi c jams etc.)

To regenerate the fi lter, it is advised

to drive as soon as possible, when

traffi c conditions permit, at a speed

of 40 mph (around 60 km/h) or

more for at least fi ve minutes (until

the alert message disappears).
If this alert persists, consult a
CITROËN dealer.

Refer to the Maintenance and Warranty
Guide for details of the replacement in-
terval for this component.

C H E C K S

Brake pads

Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be

necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a

drop in the brake fl uid level indicates

that the brake pads are worn.

Manual gearbox

The gearbox does not re-
quire any maintenance (no
oil change).

6-speed electronic gear

control gearbox

The gearbox does not require any
maintenance (no oil change).

Automatic gearbox

The gearbox does not require any
maintenance (no oil change).

Brake disc wear

For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.

Parking brake

If a loss of effectiveness of this sys-
tem is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a
CITROËN dealer.

Only use products recom-
mended by CITROËN or
products of equivalent quality

and specifi cations.

In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers

very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment is
strictly prohibited .

CHANGING A BULB

Procedure for replacing a faulty bulb

with a new bulb without the use of
tools.

In some climatic conditions (e.g.

low temperature or humidity), the

presence of misting on the internal

surface of the glass of the head-

lamps and rear lamps is normal;

it disappears after the lamps have

been on for a few minutes.

The headlamps are fi tted

with polycarbonate glass

with a protective coating:

 do not clean them using a

dry or abrasive cloth, nor
with a detergent or solvent
product,



use a sponge and soapy water,



when using a high pressure

washer on persistent marks, do

not direct at the lamps or their

outlines for too long, so as not

to damage their coating and

their seals.



Do not touch the bulb directly

with your fi ngers, use lint-free

cloths.

Changing a halogen bulb should

only be done after the headlamp

has been switched off for a few

minutes (risk of serious burns).

It is imperative to use only anti-

ultraviolet (UV) type bulbs in order

not to damage the headlamp.

Dipped beam headlamps



Remove the rubber cover.



Rotate the bulb-holder a quarter

turn anti-clockwise and remove it

from its housing.



Replace the faulty bulb.



Reposition the bulb-holder by

pushing it in, tightening it by a

quarter turn clockwise.



Refi t the rubber cover.
