Ventilation, Heating and Air Conditioning of the Passenger Compartment

GENERAL INFORMATION.

Ventilation and Heating.

A mixing system of cold and

hot air is used to control the air temperature. This system provides low-inertia control of

air temperature, which is practically independent of vehicle speed.

The air flow into the passenger compartment is determined by the fan speed. Therefore, the fan must be switched on as needed, even when the vehicle is moving. To heat the rear seat passenger footwell area, warm air is supplied through ducts located under the floor mat.

Center Air Vents

Air can enter the passenger compartment through both center air vents. The air

flow volume is controlled by the air flow control, located between the grilles.

The air flow direction from the center vents can be adjusted as desired in both horizontal and vertical planes using the levers that provide tilt and swivel of the

vents.

vents.

Side Air Vents.

Air can enter the passenger compartment through the left and right side

vents.

Front Door Window Defroster Nozzles

Cold or warm air is directed to defrost both the windshield and the front door

side windows (mainly the areas that provide visibility of the outside rear view mirrors).

Passenger Compartment Air Conditioning System.

The ventilation, heating and air conditioning systems are

A single functional system designed to provide maximum

comfortable conditions in the vehicle in any season, regardless of weather

and outside air temperature. The air conditioning cooling unit

reduces air temperature and humidity and also filters dust from the air. The heater unit of the heating system raises the temperature

of the air in all operating modes depending on the position of the control.

temperature. The amount of air entering the cabin depends on the blower fan speed.

Air Conditioning Switch

The button is used to turn the air conditioning on and off.

air.

Start the engine, use the blower switch to select the desired fan speed, and press the air conditioning button. The indicator lamp will illuminate when the air conditioning is on. To turn off the air conditioning, press the same button again.

Note that the air conditioning will not turn on if the blower switch is in the OFF position or if the outside air temperature is below 0° C.

Warning.

If the air conditioning system is operating while the vehicle is moving

on long uphill grades or in heavy city traffic, monitor the engine temperature. Operating the air conditioning under these conditions may cause the engine to overheat. If the coolant temperature exceeds the permissible value, turn off the air conditioning system.

Air Temperature Control

The control provides smooth adjustment of the air temperature entering the vehicle cabin over a wide range.

Outside air may be heated, cooled, or directed into the cabin without temperature change. Moving

the control lever to the left increases the flow of cooled air (blue zone).

Moving the control lever to the right increases the flow of heated air (red zone).

Blower Fan Speed Switch

The switch is used to control the blower fan speed. There are four fan speeds in total

Air Distribution Control

The control is used to select the desired air distribution mode for air entering the cabin.

Upper level mode: air enters the cabin through the center and side vents

.

Bi-level mode: air enters the cabin through the center, side and floor vents in the front footwell area

for the front passenger and driver.

Floor mode: air mainly enters the cabin through the vents

in the front footwell area for the front passenger and driver.

Defrost: air is directed to the windshield and front door windows.

Recirculation Switch

Press the switch when driving in heavily dusty areas or in dense traffic to prevent dust and polluted air from entering the cabin. This mode can also be useful for quickly reducing or increasing the cabin air temperature. When recirculation is on, the indicator lamp illuminates and outside air intake stops.

To turn off recirculation and resume fresh air ventilation of the cabin, press the same button again. The indicator lamp will go off.

Warning.

Do not use recirculation mode for extended periods. This may increase humidity in the cabin and cause the windows to fog.

Driving with fogged windows is dangerous, as visibility is reduced and the risk of a road traffic accident increases.

Maximum cooling mode

Recommended for hot weather and after the vehicle has been parked in the sun for a long time. Open the windows briefly to vent hot air from the cabin.

Air conditioning switch: ON.

Recirculation switch: ON.

Air distribution control:
Air temperature control: fully left position (blue zone).

Blower fan speed switch: position 4.

Normal cooling mode

Recommended for city and highway driving.

Air conditioning switch: ON.

Recirculation switch: OFF.

Air distribution control:or.

Air temperature control: in the blue zone.

Blower fan speed switch: as desired.

Bi-level ventilation mode

Recommended for intermediate seasons when outside air temperature is low and there is insufficient sunlight.

If the air temperature control is set to the middle position (between the blue and red zones), warmer air will be directed to the footwell area and cooler air to the upper part of the cabin.

Air conditioning switch: ON.

Recirculation switch: OFF.

Air temperature control: between the blue and red zones.

Blower fan speed switch: as desired.

Air temperature control: as desired.

Blower fan speed switch: as desired.

Warning.

To prevent windows from fogging in rainy weather, set the air distribution control to the defrost position when cold outside air enters the cabin (heater off). The difference between the outside air temperature and the windshield temperature may cause moisture to condense on the inside of the glass

and reduce visibility from the vehicle.

Air conditioner operating recommendations.

If the vehicle has been parked in direct sunlight, open the windows and ventilate the interior before switching on the air conditioner.

To remove condensation from fogged windows in rainy weather, reduce

the interior air temperature by switching on the air conditioner. This method is useful in the rainy

season, when air humidity is very high.

When driving in the city with heavy traffic, the efficiency of the air conditioning

system may decrease due to frequent stops and slow traffic movement.

of the vehicle at low speed.

If the air conditioner is not used for a long time (one month or more),

it is necessary to switch it on for several minutes once a week, even in winter. Before

switching on the air conditioner, start the engine. Periodic switching on

of the air conditioner helps maintain the lubricant film on the compressor parts and

seals, and also extends the service life of the air conditioning system.

The air conditioning compressor does not engage if the fan switch is in the OFF position or the ambient air temperature is below 0°
