Air conditioning

To ensure that your system operates
correctly, it is recommended that you
have it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To preserve the sealing of the air
conditioning compressor, operate
the air conditioning at least once a
month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, then close them again.
The air conditioning operates by
using power from the engine. This
results in a slight increase in fuel
consumption.


Dust filter/Odour filter (active
carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle's servicing
schedule (see the servicing booklet).


Air circulation

Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.


Air vents

The air vents to the face have grilles
and thumb wheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning in the passenger com-
partment uses a number of sensors
(sunshine sensor, ambient tempera-
ture sensor...) that relieve you of the
need to make frequent adjustments to
the displayed temperature.
Take care not to obstruct the sun-
shine sensor, located on the dash-
board behind the instrument panel.

CHECKS






CHECKS












12 V battery

The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical information"
section for details of the precautions
to be taken before disconnecting 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 oc-
casionally notice water vapour be-
ing emitted from the exhaust when
accelerating. This is of no conse-
quence 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 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 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.
