In order for these systems to be fully effective, follow the operation and maintenance guidelines below:  If the interior temperature remains very high after the vehicle has been parked in the sun for a considerable time, first ventilate the passenger compartment for a few minutes. Place the air flow control at a sufficient level to provide an adequate renewal of air in the passenger compartment.  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.  Use in preference the intake of exterior air as prolonged use of the air recirculation may cause misting of the windows and side windows.  Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the automatic air conditioning system.  Operate the air conditioning system for 5 to 10 minutes, once or twice a month to keep it in good working order.  Ensure that the passenger compartment 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 compartment filter. Thanks to its second special active filter, 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).  The air conditioning uses power from the engine while operating. This results in an increase in the vehicle's fuel consumption. When towing at or near maximum capacity or on steep slopes in high ambient temperatures, switching off the air conditioning saves engine power and so improves towing capacity. Condensation created by the air conditioning results in a discharge of water under the vehicle when stationary, which is per fectly normal.  To ensure correct operation of the air conditioning system, you are also advised to have it checked regularly.  If the system does not produce cold air, do not use it and contact a PEUGEOT dealer or a qualified workshop.
Recommendations for ventilation and air conditioning
The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.

Automatic operation
1. Automatic comfort programme
 Press this "AUTO" button. The indicator lamp comes on.
We recommend that you use this mode. It automatically adjusts all settings to provide optimum operation for the comfort level chosen: passenger compartment temperature, air flow, air distribution and air recirculation. This system is designed to operate effectively in all seasons, with the windows closed.
When the engine is cold, to prevent too great a distribution of cold air, the air flow will reach its optimum level gradually. In cold weather, it favours the distribution of warm air to the windscreen, side windows and footwells o n l y.

 Turn control 2 or 3 to the left (blue) or to the right (red) respectively to decrease or increase this value.
A setting around the value 21 provides optimum comfort. However, depending on your requirements, a setting between 18 and 24 is normal. It is recommended that the difference between left and right should not be greater 3.
