Continue until all the water has
fl owed out.
Then tighten the bleed screw or the
water detection sensor.

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 3.5 litres,
- screenwash and headlamp wash:
approximately 6.15 litres.
Diesel additive level
(Diesel engine with particle
emission filter)
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
minimum level of this fl uid
is indicated by an audible
signal and a message in the multi-
function screen.
Top up the level when you stop the
vehicle.
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 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 oper-
ate 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 pressure has dropped, remove
the cap and top up the level. The additive reservoir
low level is indicated
by fi xed illumination
of this warning lamp,
accompanied by an audible warning
and a message in the multifunction
screen.

CHECKS
CHECKS
Unless otherwise indicated, check
these components in accordance with
the servicing booklet and according to
your engine.
Otherwise, have them checked by a CITROËN dealer or a qualifi ed workshop.
Battery
The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly 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 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 undesirable
odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed.
Particle filter system (Diesel)
Complementary to the catalytic con-
verter, this fi lter makes an active
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 blockage, a mes-
sage appears in the instrument
panel screen, accompanied by an
audible signal and illumination 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 exception-
ally 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. Refer to the servicing booklet for de-
tails of the replacement interval for
this component.
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 recommenda-
tion may shorten the life of the battery.
