AIR CONDITIONING
This system automatically adjusts the temperature, the fl ow of air and the distribution of air inside the cabin, depending on your desired comfort level.
Provided you retain automatic mode (by pressing button "AUTO") and all the air vents are open, you will main-tain an optimum comfort level, also removing humidity and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than the temperature outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the windows closed. If after a lengthy stop in bright sunlight the interior temperature is excessive, air the passenger compartment by opening the windows for a few moments, then close them again.
To keep the air conditioning compressor well sealed, it is essential to operate the air conditioning at least once in every month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
Sensors
The automatic regulation of the air conditioning inside the cabin makes use of a number of sensors, relieving you of the need to make adjustments, other than the desired cabin temperature.
Take care not to obstruct sensor A.
Air inlet
Check that the exterior grille for the air inlet, at the bot-tom of the windscreen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
The air vents to the face have thumbwheels so that you can adjust the fl ow of air, and grilles to orient the direction.
There are air vents on the fl oor underneath the front seats and on the rear control panel, for enhanced heat-ing of the rear seat positions.
Do not obstruct the air outlets located in the boot area.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This fi lter has to be changed according to the vehicle maintenance schedule. See "Maintenance Guide".

The system has a differentiated adjustment for the driver's side and passenger's side, in terms of temperature and air distribution. The air fl ow is common to both sides.
Symbols and messages relating to the automatic air conditioning controls will display on the multifunction screen.
2. TEMPERATURE ADJUSTMENT
To adjust the temperature, press button 2a for the driv-er's side and button 2b for the passenger's side.
An adjustment around 21 will give you the optimum comfort level. However, depending on your preferences anywhere between 18 and 24 is quite usual.
Operating the air conditioning system on "AUTO" guar-antees good ventilation inside the cabin.Note: there may be a difference between the actual cabin temperature and the fi gure displayed.
This is the normal operating mode for the system. Depending on the temperature chosen, a press on this button, confi rmed by the lighting of the warning lamp, will automatically and simultaneously bring all the fol-lowing functions into play:Air fl ow.
Cabin temperature.
Air distribution.
Exterior air intake/Air recirculation.
It is recommended to keep all the air vents open. Just by pressing any of the buttons, except for temperature 2a and 2b, you can change to manual mode. the warn-ing lamp goes out. The warning lamp goes off, and the automatic air intake function is deactivated.

Remarks:When starting from cold, in order to prevent unwanted cold air, the air fl ow will increase only gradually to its optimum level.
If you enter the vehicle after a fairly prolonged stop and the temperature inside the vehicle is far from comfortable, it serves no purpose to modify the temperature that is displayed as an attempt to go immediately to the desired comfort level. The system automatically uses all of its power to compensate the temperature gap as quickly as possible.
Remarks:Water arising from the condensation in the air conditioning drains out through a hole provided for this purpose ; a pool of water may thus form underneath the vehicle when stationary.
Whatever the time of year, even in cool weather the air conditioning is useful in removing humidity and misting.You are advised to have the air conditioning system checked on a regular basis. See "Maintenance Guide".
If you are towing a heavy trailer and outside temperatures are high, the air conditioning may be temporarily paused if the engine cooling requires this.

5. FRONT DEMISTING - DEICING
Press button 5 for rapid clear windows. The warning lamp comes on. This system controls the air condi-tioning, the air fl ow and the entry of air from outside. It sends the ventilation towards the windscreen and side windows.
A press on the 1 button returns you to "AUTO" mode.
6. REAR DEMISTING - DEICING
Press button 6, with the engine running, to start a rapid deicing or demisting of the rear screen and rear view mirrors. The warning lamp comes on.
This mode stops automatically as a function of the out-side temperature. It can be paused by pressing again on button 6 or by stopping the engine.
In the latter case, demisting will resume when the engine is switched on again.Note: The heated rear screen operates independently of the automatic air conditioning.
7. AIR RECIRCULATION – ENTRY OF AIR FROM OUTSIDE
Press repeatedly on button 7 to select the air entry mode. The corresponding warning lamp lights up:Air intake in automatic pollution control mode (on by default, with automatic comfort regulation).
The automatic mode makes use of an air quality sen-sor. It analyses the air and isolates the cabin from the exterior if the presence of pollutants is detected. In this case it automatically activates recirculation of the cabin air.
Please note: this function does not detect and there-fore protect the cabin from unpleasant odours. It is not active when the ambient temperature is below + 5 °C so as to avoid the risk of misting the vehicle’s windows.
Closing the exterior air intake
Press button 7 to close the intake of air from the exte-rior.
While maintaining the other settings, this position allows the driver to avoid unpleasant odours and smoke out-side the vehicle at any time.
