The climate in the vehicle is controlled by means of the duct/distributor and heater unit.

The air conditioning system integrates the heater with the function of producing cold and dehumidified air, achieved by switching on the compressor and the cooling system.

The climate control system is controlled by operating two knobs with their associated wheels located on the central part of the dashboard:

• the ring nut on the left-hand knob mechanically controls the blend of hot and cold air;

• the left knob allows the adjustment, through an electric control, of the air ventilation at four different speeds;

• via a cable, the ring nut on the right-hand knob mechanically controls the opening of the flaps that govern air flow distribution;

• the right knob makes it possible to select whether or not to set the "recirculation" function which prevents the intake of new air into the passenger compartment.

There is a button, in between the two knobs, for switching the climate control system compressor on. The function is activated by pressing the passenger compartment air intake speed selector knob and turning it to a position other than the rest position.

The activation of the air conditioning compressor is signalled by the LED in the button coming on.

To deactivate the function simply press the same button again.
