Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air fl ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (ambient temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.

 Take care not to cover the sun-
shine sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and leave
all of the vents open, optimum comfort
will be maintained and humidity and
condensation will be removed regard-
less of the exterior climatic conditions.
The temperature in the passenger
compartment can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air con-
ditioning must be used with the win-
dows closed. If the vehicle has been
parked in the sun for a long period
and the interior temperature is very
high, fi rst ventilate the passenger
compartment with the windows
open for a few minutes, then close
the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses engine
power during its operation. As a re-
sult, the fuel consumption of the ve-
hicle increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high
temperatures), switching off the air
conditioning saves engine power
and improves the towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spraying
at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter must be changed in line
with the vehicle's servicing schedule
(see: "Maintenance and Warranty
Guide").

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 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 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 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 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 replacement interval for this
component.
