In order for these systems to be fully effective, follo w 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 passeng er compartment for a few minutes. Place the air flow control at a sufficient level to provide an adequate renewal of air in the passenger compar tment.  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 prol onged use of the air recirculation may cause misting of the windows and side windows.  Do not cover the sunshine sensor, located on the d ashboard; this is used for regulation of the automatic air conditioning system.  Operate the air conditioning system for 5 to 10 minut es, once or twice a month to keep it in good working order.  Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" secti on). We recommend the use of a combined passenger compa rtment filter. Thanks to its second special active filter, it contributes to the purification of the air breathed by the occupants and the cleanli ness 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 conditionin g
The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.

Manual air conditioning
The air conditioning system operates with the engine running.
1. Temperature adjustment
 Turn the dial from left (cold) to right (hot) to adjust the temperature to your requirements.
2. Air fl ow adjustment
 Press the "full fan" button to increase the air flow.
 Press the "empty fan" button to reduce the air flow.
3. Air distribution adjustment
 press the corresponding button for:
Windscreen and side windows.
Central and side vents.
Footwells.
Depending on your requirements, you can combine two distribution buttons or select the three distribution modes simultaneously.
According to the value selected, the associated line of LEDs fills progressively.

4. Air intake/Air recirculation
 Press this button to recirculate the interior air. The indicator lamp comes on to confirm this.
 Press the button again to permit the intake of exterior air. The indicator lamp goes off to
confirm this.
The intake of exterior air prevents the formation of mist on the windscreen and side windows. The recirculation of interior air isolates the passenger compar tment from exterior odours
and smoke. Return to exterior air intake as soon as possible to prevent deterioration of the the air quality and the formation of mist.
6. Automatic visibility programme 5. Air conditioning On/Off
The air conditioning is designed to operate effectively in all seasons, with the windows closed.
It enables you to: - lower the temperature, in summer, - increase the effectiveness of the demisting in winter, above 3 °C.
Switching on
 Press the "A /C" button, the associated green indicator lamp comes on. The air conditioning does not operate when the air flow adjustment is set to off.
Switching off
 Press the "A /C" button again, the associated green indicator lamp switches off. Switching off may result in some discomfor t (humidity, misting).
See "Front demisting - Defrosting".

Dual-zone digital air conditioning
The air conditioning system operates when the engine is running.
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 comfor t level chosen: passenger compar tment 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 only.
2 - 3. Driver-passenger side adjustment
The driver and front passenger can each adjust the temperature to their requirements. The value indicated on the display corresponds to a level of comfor t and not to a temperature in degrees Celsius or Fahrenheit.
 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.

Comfort
On entering the vehicle, if the interior temperature is much colder or warmer than the comfor t value, there is no need to change the value displayed in order to obtain the comfor t required. The system corrects the difference in temperature automatically and as quickly as possible.
4. Automatic visibility programme
For maximum cooling or heating of the passenger compar tment, it is possible to exceed the minimum value 14 or the maximum value 28.  Turn control 2 or 3 to the left until "LO" is displayed or to the right until "HI" is displayed.
See "Front demisting-defrosting".
 Press this button to equalise the comfor t value on the passenger's side with that on the driver's side (mono-zone). The indicator lamp on the button comes on.
If you wish, you can change one of settings provided by the system. The other functions will still be controlled automatically.  Pressing the "AUTO" button returns the system to completely automatic operation.
Manual operation
5. Mono-zone/Dual-zone
The air conditioning is designed to operate effectively in all seasons, with the windows closed.
6. Air conditioning On/Off
It allows you: - in summer, to lower the temperature, - in winter, above 3 °C, to improve demisting per formance.
7. Maximum air conditioning
If you want to temporarily refresh the air in the passenger compar tment, press this button and "LO" is displayed. To return to the previous settings, press the button again.
With Stop & Star t, when demisting has been activated, the STOP mode is not available.
Switching on Press the "A /C" button, the associated
green indicator lamp comes on. The air conditioning does not operate when the air flow control is set to off.
Switching off Press the "A /C" button again, the associated green indicator lamp goes off. Switching off the air conditioning may result in some discomfor t (humidity, misting).

Switching the system off
 Press this button for recirculation of the interior air. The indicator lamp on the button comes on.
Air recirculation enables the passenger compar tment to be isolated from exterior odours and smoke. It is activated automatically when operating the screenwash.
Avoid driving for long periods with the system off (risk of condensation and deterioration of the air quality). Pressing the "full fan" button reactivates the system with the values in use at the time it was switched off.
The air flow symbol, the fan, fills progressively according to the value requested.
This action switches off all of the functions of the air conditioning system. Temperature related comfort is no longer guaranteed but a slight flow of air, due to the forward movement of the vehicle, can still be felt.
 As soon as possible, press this button again to permit the intake of outside air and prevent the formation of condensation. The indicator lamp in the button goes off.
