Note: Air conditioning system is installed on some vehicles.
The system provides low-inertia regulation of air temperature, practically independent of the vehicle speed. The amount of air entering the cabin is mainly determined by the fan operating mode, so it should be turned on even when driving at high speed.
Outside air can enter the passenger compartment through the door windows when the windows are lowered and the air blower located in front of the windshield. Air from the air blower can enter the passenger compartment of the car through the windshield blower nozzles, side and central nozzles, as well as through the lower nozzles of the heater housing.
The quantity, temperature, direction and intensity of air flows are regulated by switches installed in the control unit of the heating, ventilation and air conditioning systems.
To change the temperature of the air entering the cabin, turn the temperature control knob. The blue part of the scale corresponds to the supply of the coolest air, the red part corresponds to the supply of the warmest air. When the knob is in the middle position, air is supplied to the cabin at the ambient temperature.
To increase the intensity of air supply to the passenger compartment while driving and to ensure air supply to a stationary vehicle, use the switch handle to turn on one of the four operating modes of the air blower fan.
To change the direction of air flow, use the air flow distribution control knob to select one of four options (clockwise):
- air supply to the upper part of the cabin (through the side and central nozzles of the instrument panel);
- air supply to the upper and lower parts of the passenger compartment (through the side and central nozzles of the instrument panel, as well as through the lower nozzles of the heater housing);
- air supply to the lower part of the passenger compartment (through the lower nozzles of the heater housing);
- supplying air to the windshield (through the windshield blower nozzles).
To cool the air entering the car, press the air conditioner button (if installed on the car) - a green indicator light will light up. To turn off the air conditioner, press the button again.
Note: The air conditioner will not turn on if the air blower fan mode switch is set to position "0" (fan off) or the ambient temperature is below 0°C. This is not a malfunction, but is provided for by the design.
Caution! Turning on the air conditioner while the engine is running in difficult conditions (long climbs, heavy city traffic, etc.) may cause the engine to overheat. Monitor the coolant temperature gauge: if the temperature exceeds the permissible value, turn off the air conditioner. During long trips in city traffic, the efficiency of the air conditioner may decrease due to the intense thermal conditions of the engine. This is not a sign of a malfunction; when driving in normal road conditions, the air conditioner will work effectively.
To turn on the recirculation mode, press the recirculation mode switch (the indicator lamp in the switch will light). When the recirculation mode is on, outside air does not enter the passenger compartment, and the air blower fan ensures air circulation inside the passenger compartment. This mode is used to quickly warm up the passenger compartment in cold weather, as well as in cases of increased dustiness and gas pollution of the surrounding air.
Attention! It is not recommended to keep the recirculation mode on for a long time while the car is moving, as this usually leads to fogging of the windows.
Depending on the various combinations of the control unit switches, the heating and ventilation system operates in the following main modes:
– maximum cooling mode. Used in hot weather and after prolonged parking in the sun to quickly cool the air in the cabin. In this case, before turning on the air conditioner, it is recommended to briefly open the windows to remove heated air from the cabin. The air conditioner and air recirculation switches must be turned on;
- normal cooling mode. Used when driving around town and outside the city in moderately warm weather. The air conditioner switch should be on, the recirculation switch should be off;
- ventilation mode. It is used in the off-season, which is characterized by low temperatures;
– maximum heating mode. Used at very low ambient temperatures and to quickly warm up the air in the cabin after a long period of parking. The air conditioner switch must be off, the recirculation switch must be on;
- normal heating mode. Used in the cold season to maintain the optimum air temperature in the cabin after its intensive heating in the maximum heating mode. The air conditioner and air recirculation switches must be turned off;
– windshield and front door glass blowing mode. Used to quickly eliminate fogging of glass in high humidity. The air conditioner switch can be in any position depending on the ambient temperature, and the recirculation switch must be off.
Note: To prevent the glass from fogging up in rainy weather, turn on the blowing mode with the heater turned off, since the difference in temperature between the glass surface and the supplied air can cause condensation.
Note: For more efficient ventilation and heating at vehicle speeds below 50 km/h and when driving on particularly dusty road sections with closed windows (to create excess air pressure in the cabin, preventing dust suction), we recommend switching the heater fan to low or maximum speed using the switch.
Note: To quickly eliminate fogging of the rear window and free it from ice and snow, turn on the heated glass switch.
Note: If you do not use the air conditioner for a long time, it is necessary to turn it on briefly once a week with the engine running to restore the lubricant layer on the compressor parts and seals.
