Interior ventilation
Outside air can enter the vehicle interior:
- with the door windows down;
- through the upper nozzles on the instrument panel, if you move the distribution lever 5 to the right (fig. 31, 32) and lever 6 for controlling the air intake hatch cover;
- through the side nozzles 1 on the instrument panel, if you move lever 6 to the right and lever 5 to the left;
- through the holes in the heater casing, if you open the air distribution cover with lever 3 and move lever 6 to the right;
- through the central nozzles 10 directly from the air intake box when the car is moving, if the nozzle flaps are opened with the regulators 8 (summer blowing).
By moving the lever 9 in horizontal and vertical directions the direction of the air flow changes.
In the middle position of lever 5 and in the right extreme position of lever 6, air will flow through both the upper and side nozzles.
By turning the guide blades of the side nozzles, the direction of the air flow changes.
If the vehicle is moving at low speed, the amount of incoming air can be increased by turning on the heater electric fan using switch 2.
Protection against fogging of the windshield, front door windows and rear window
To prevent the windshield and front door windows from fogging up, simply direct cold air at them, for which:
- close the heater air distribution cover with lever 3;
- move lever 6 to the right and set lever 5 to the middle position;
- turn the side vent guide vanes so that the air flow is directed towards the front door windows.
If you need to slightly warm up the incoming air, move the heater valve control lever 7 partially to the right. If necessary, turn on the heater electric fan.
To prevent the rear window from fogging up, turn on its electric heating using switch 4.
Interior heating
To heat the car interior and protect the windshield, front door windows, and rear window from fogging and freezing:
- move levers 6 and 7 to the right;
- set lever 5 to the middle position;
- open the heater air distribution cover with lever 3;
- turn on the rear window heating;
- turn on the heater electric fan if necessary;
- turn the side vent guide vanes so that the air flow is directed towards the front door windows.
Warm air will be directed both to the driver's and passengers' footwells and to the windshield and front door windows. To heat only the windshield more quickly, close the heater cover and move lever 5 to the right.
