The climate in the vehicle is controlled by means of the duct/distributor and heater unit and is controlled via the two control knobs and ring nuts in 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.

The fan is controlled by a dedicated relay switch and is protected by a dedicated fuse located in the engine compartment junction unit.
