- 1 – engine cooling system fluid temperature indicator;
- 2 – rotary deflectors;
- 3 - air intake hatch (on the engine hood;
- 4 – air intake hatch cover;
- 5 – coolant drain pipe;
- 6 – pipeline for supplying hot liquid to the heater radiator;
- 7 – heater tap;
- 8 – air distribution cover of the heater casing;
- 9 – heater tap control lever;
- 10 – air intake hatch control lever;
- 11 – three-position switch for the heater electric fan.
- Blue arrows - cold air;
- pink arrows – heated air;
- red arrows - coolant
The figure shows:
- location of controls for ventilation and heating of the passenger compartment;
- movement of cold and heated air;
- coolant circulation.
Ventilation and heating of the passenger compartment are regulated depending on the outside air temperature.
Interior ventilation
Outside air can enter the vehicle interior:
- with the front door windows open;
- with the door windows down;
- through deflectors 2, if you move the upper lever 10 for controlling the air intake hatch cover to the right;
- with the air distribution cover 8 open, if you move the upper lever 10 to the right.
When turning the deflectors, the direction of the air flow changes. If necessary, you can increase the amount of incoming air by turning on the electric fan with switch 11 to the appropriate mode.
Preventing windshield fogging
To prevent the windshield from fogging up, it is enough to direct cold air at it, for which it is necessary to move the upper lever 10 to the right, close the cover 8 and turn the deflectors so that the air flow is distributed over a larger area of the windshield. To heat the incoming air, move the lever 9, which regulates the flow of coolant into the heater radiator, partially to the right.
Interior heating
To heat the car interior and protect the windshield from freezing:
- move levers 9 and 10 to the right;
- turn on the heater electric fan;
- open the air distribution cover 8.
Warm air will be directed both to the driver's and passengers' footwell and to the windshield. For faster windshield heating, close cover 8. If the ambient temperature is very low, move lever 10 to the right for part of its travel to limit the flow of cold air.
