is filtered and originates either from the outside via
the
grille located at the base of the windscreen or from the inside in air recirculation mode.
Air treatment
The incoming air follows various routes
depending on the controls selected by thedriver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).

The controls of this system are grouped
together on control panel A on the centreconsole.

Comfort
In order for these systems to be fully effective, follow the operation and maintenance guidelines below: )
To 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 wellas the air extractor located in the boot. )
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the digital air conditioning system. )
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a monthto keep it in per fect working order. )
Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly. We 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 theoccupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad odours and greasy deposits).)
To ensure correct operation of the air conditioning system, you are also advised to haveit checked regularly as recommended in the ser vicing booklet. )
If 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, firstventilate 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 notcontain chlorine and does not present any danger to the ozone layer.

The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.


When towing the maximum load on a steep gradient in high temperatures, switching off theair conditioning increases the available engine power and so improves the towing ability.

When the engine is cold, to avoid an excessive distribution of cold air, theventilation 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 thetemperature setting in order to reachthe comfor t required rapidly.
The automatic regulation of the air conditioning will operate to correct thetemperature difference as quickly aspossible. In
automatic mode:)when the temperature is set to maximum (Rapid heating), the intake of exterior air is
activated and the air conditioning stops.)when the temperature is set to minimum(Rapid cooling), air recirculation isactivated 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.
