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 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 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 ensure correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the Maintenanc e 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.

Digital air conditioning
The air conditioning operates when the engine is r unning, as well as in STOP mode with Stop & Start.
Automatic operation
1. Automatic "comfort" programme
Press the "AUTO" button. The "AUTO" symbol is displayed. We recommend that you use this mode. It provides optimised automatic control of all of the following functions: passenger compar tment temperature, air flow, air distribution and air intake, in accordance with the comfor t value that you have chosen. This system is designed to operate effectively in all seasons, with the windows closed.
For your comfor t, when the engine is switched off, the settings are retained until the engine is switched on again. To prevent too great a distribution of cold air when the engine is cold, the air flow will only reach its optimum level gradually.
2. Temperature adjustment
The value indicated on the display corresponds to a level of comfor t and not to a temperature in degrees Celsius or Fahrenheit.
On entering the vehicle, if the interior is very cold or hot, there is no need to change the value displayed in order to reach the required level of comfor t. The system corrects the temperature difference automatically and as quickly as possible.
Press the "" and "" buttons to change this value. A setting around the value 21 enables optimum comfor t to be obtained. However, depending on your requirements, a setting between 18 and 24 is usual.
3. Automatic "visibility" programme
The automatic comfor t programme may not be sufficient for rapid demisting or defrosting of the windscreen and side windows (humidity, several passengers, ice, etc.). In this case, select the automatic visibility programme. The button 3 indicator lamp comes on. The system automatically controls the air conditioning and the flow of air and provides optimum air distribution to the windscreen and side windows. It deactivates air recirculation 5 .
To exit this programme, press button 3 again or "AUTO" , the indicator lamp on the button goes off and "AUTO" is displayed.
With Stop & Star t, when demisting has been activated, the STOP mode is not available.

Rear screen demist - defrost
The control button is located on the heating or air conditioning system control panel.
Switching on
The rear screen demisting/defrosting can only operate when the engine is running.  Press this button to demist /defrost the rear screen and (depending on version) the door mirrors. The indicator lamp associated with the button comes on.
Switching off
The demisting/defrosting switches off automatically to prevent an excessive consumption of current.  It is possible to stop the demisting/defrosting operation before it is switched off automatically by pressing the button again. The indicator lamp associated with the button switches off.  Switch off the demisting/defrosting of the rear screen and door mirrors as soon as appropriate as lower current consumption results in reduced fuel consumption.
If the engine is switched off before the demisting/defrosting is switched off automatically, demisting/defrosting will resume next time the engine is switched on.
