Recommendations for ventilation and air co nditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the passenger compar tment for a few moments.
Put the air flow control at a setting high enough to quickly change the air in the passenger compar tment. The air conditioning system does not contain 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 well as the air extractor located in the boot.  Do not cover the sunshine sensor, located on the d ashboard; this is used for regulation of the air conditioning system.  Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month to keep it in per fect working order.  Ensure that the passenger compar tment filter is in g ood condition and have the filter elements replaced regularly (refer to the "Checks" secti on). We recommend the use of a combined passenger compa r tment 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 compar t ment (reduction of allergic symptoms, bad odours and greasy deposits).  To guarantee correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the Maint enance and Warranty Guide.
 If the system does not produce cold air, deactivate it and contact a CITROËN dealer. 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.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.
