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 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 vehi cle maintenance schedule. See "Maintenance and Warranty Guide".
