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 water.
Reservoir capacities:
- screenwash: approximately 3.5 li-tres,
- screenwash and headlamp wash: approximately 6.15 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 u-
ids into sewers or onto the
ground.
Take used oil to a CITROËN deal-
er (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 sig-
nal and a message on the multifunc-
tion 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 tem-
perature of the coolant is regulated
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 al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your en-
gine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and cor-
rectly tightened, particularly
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.
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" 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. 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 instrument
panel display, 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 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 re-
placement 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 is required when replacing or
disconnecting the battery.
Failure to observe this recommen-
dation may cause premature wear
of the battery.
