Air intake
The air circulating in the passenger compar tment
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 routesdepending on the controls selected by
the driver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.
The air distribution control enables you to
di
ffuse the air in the passenger compar tment combining several air vents.
The air flow control enables you to increase or reduce the speed of the ventilation blower.

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, 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 notcontain chlorine and does not present any danger to the ozone layer.

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 perfect working order. )
Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" section). We recommend the use of a combined passenger compar tment 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.
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.

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

4. Air intake/Air recirculation

The intake of exterior air avoids the formation of mist on the windscreen and side windows.
The recirculation of interior air insulates thepassenger compar tment from exterior odours and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the air quality and
the formation of mist.
