AIR CONDITIONING
This system automatically adjusts the temperature, the fl o w o f a i r a n d t h e d i s t r i b u t i o n o f a i r i n s i d e t h e c a b i n , 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 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 a d j u s t t h e fl o w o f a i r , a n d g r i l l e s t o o r i e n t t h e d i r e c t i o n .
T h e r e a r e a i r v e n t s o n t h e fl o o r u n d e r n e a t h t h e f r o n t 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.

Remarks:When starting from cold, in order to prevent u n w a n t e d c o l d a i r , t h e a i r fl o w w i l l i n c r e a s e o n l y gradually to its optimum level.
If you enter the vehicle after a fairly prolonged stop and the temperature inside the vehicle is uncomfortable, 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 and Warranty 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.
