In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.
F

D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

O
perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.
F

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T
o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.
F

I
f the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine,
the interior temperature is very high, first
ventilate the passenger compartment for
a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.

Manual heating / air conditioning
The system operates with the engine running.
1. Temperature setting
F Turn the temperature control dial to the right to raise the
temperature, and to the left to
lower it.
To avoid misting and deterioration of the air
quality in the passenger compartment, ensure
that an adequate air flow is maintained.
3. Air distribution setting
F Place the dial in the desired position, to direct air towards:
t

he centre and side vents,
The air distribution can be modulated by
placing the dial in intermediate positions.
2. Air flow setting
F Turn the dial to the right to increase and to the left to
reduce the air flow.

lace the air distribution adjustment dial 3
in the "AUTO" position. When the engine is cold, to avoid an
excessive distribution of cold air, the
ventilation will reach its optimum level
gradually.
On entering the vehicle, the interior
temperature may be much colder
(or warmer) than the temperature
setting. There is no need to change the
temperature setting in order to reach
the comfort required rapidly.
The automatic regulation of the air
conditioning will operate to correct the
temperature difference as quickly as
possible.
In automatic mode:
F

w
hen the temperature is set to maximum
(Rapid heating), the intake of exterior air is
activated and the air conditioning stops.
F
w
hen the temperature is set to minimum
(Rapid cooling), air recirculation is
activated and the air conditioning operates.
The system controls the air distribution, the
flow, the temperature and the air intake to
ensure the level of comfort selected and
adequate air circulation in the passenger
compartment. No further action on your part is
required.
