1.11. Interior ventilation and heating controls
The controls for ventilation and heating of the passenger compartment are shown in Fig. 1.11.
Outside air can enter the passenger compartment through the door windows when the windows are down and through the gap between the hood and the windshield.
Air flows in the passenger compartment are distributed through air ducts located inside the instrument panel. By moving lever 2, the air flow is directed both to the driver's and passenger's foot area and through the central 8 and side 7 nozzles into the passenger compartment. By turning the guide blades of the central and side nozzles with levers 9 and 11, the air flow direction is changed.
To warm up the incoming air, move the heater control lever 3 to the right. If necessary, the electric fan switch 1 can be used to increase the amount of air entering the vehicle interior. By moving the lever 4, the intensity of the windshield blowing through the upper slits on the instrument panel and the front door windows through the nozzles 5 is regulated. To achieve maximum air flow, close the flaps of the side and central nozzles with levers 10 and 12 and move lever 2 to the right and lever 4 to the left.
