from the inside in air recirculation mode.  
Air treatment  
The incoming air follows various routes  
depending 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).  
Air distribution  
1. Windscreen demisting-defrosting vents.

Recommendations for ventilation and air conditioning  
In order for these systems to be fully effective, follow the operation and maintenance  
If after an extended stop in sunshine,  
guidelines below:  
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.  
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 well  
as 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 month  
to keep it in perfect working order.  
Ensure that the passenger compartment 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 the  
occupants 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 have  
it checked regularly as recommended in the maintenance and warranty guide.  
If the system does not produce cold air, switch it off and contact a CITROËN dealer or a  
qualified workshop.  
The condensation created by the air  
conditioning results in a discharge  
of water under the vehicle which is  
perfectly normal.  
Stop & Start  
The heating and air conditioning  
systems only work when the engine  
is running. To maintain a comfortable  
temperature in the passenger

compartment, you can temporarily  
deactivate the Stop & Start system (see
