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.

164

C H E C K S

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.
