RUNNING OUT OF FUEL(DIESEL)
1.6 litre HDi engine
Detach the protective cover for ac-
cess to the priming pump.
2.0 litre HDi engine
Detach the protective cover for ac-
cess to the priming pump.
Priming the fuel system
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 repairs must
be done only by a CITROËN dealer
or a qualifi ed workshop.

CHECKING LEVELS
Oil level
Oil specifi cation
The oil must be the correct grade
for your engine and conform to the
manufacturer's recommendations.
Brake fluid level
Changing the fl uid
Refer to the servicing booklet for
details of the interval for this opera-
tion.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer’s recommendations
and meet the DOT4 standard.
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.
This manual check will only be cor-
rect if the vehicle is on level ground
and the engine has been off for more
than 30 minutes.
It is normal to top up the oil lev-
el between two services (or oil
changes). CITROËN recommends
that you check the level, and top
up if necessary, every 3 000 miles
(5 000 kms). The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.
Take care when working
under the bonnet, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fluid level
The power steering fl uid
level should be close to the
"MAX" mark. With the engine
cold, unscrew the cap to
check the level.
If a level drops signifi cantly, have
the corresponding system checked
by a CITROËN dealer or a qualifi ed
workshop.
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
Engine oil change
Refer to the servicing booklet for de-
tails of the interval for this operation. After topping up the oil, the check
when switching on the ignition with
the oil level indicator in the instru-
ment panel is not valid during the
30 minutes after topping up.

CHECKS
Screenwash and headlamp wash
fl uid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible
warning and a message in the multi-
function screen.
Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop 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
or a qualifi ed workshop (France) or
to an authorised waste disposal
site.
In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.
Coolant level
Changing the coolant
The coolant does not have to be
changed.
Fluid specifi cation
The coolant must conform to the
manufacturer’s recommendations.
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
regulated by the fan. This can ope-
rate 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
engine 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 al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.

12 V battery
The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, parti-
cularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
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 occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. 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 audible
signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in conditions
of urban driving of exceptionally 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 or a qualifi ed
workshop.
The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer or a qualifi ed workshop is
required when replacing or discon-
necting the battery. Failure to observe this recommen-
dation may shorten the life of the
battery.
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualifi ed
workshop.
Air filter and passenger
compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), replace them twice as often
if necessary
(refer to the "Engines"
section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.
