Ventilation and heating (Chevrolet Aveo T200)

To regulate the air temperature, a system of mixing cold and hot air is used. This system provides low-inertia regulation of the air temperature in the cabin. The temperature in the cabin is maintained almost constant throughout the entire range of vehicle speeds.

The amount of air supplied to the passenger compartment is determined by the rotation speed of the fan. Therefore, for the heating and ventilation system to work effectively, the fan must be turned on even when the car is moving.

Central ventilation grilles

Air can enter the passenger compartment through both central ventilation grilles. The direction of air flow from the central grilles can be adjusted to the driver and passengers' wishes, both horizontally and vertically, using levers that tilt the grilles and turn the deflectors.

Side ventilation grilles

Air can also enter the vehicle interior through the left and right side ventilation grilles.

Windshield and front door glass defroster grilles

Cold or warm air can be supplied to blow air onto both the windshield and the side windows of the front doors (mainly in areas that provide the driver with a view through the outside rear-view mirrors).

Floor ventilation grilles

Directs air towards the foot area of the front seat passengers.

Blowing air to the rear seat footwell (optional)

Cool or warm air enters this area through the air vents located under the front seats.

Air temperature regulator

The regulator provides smooth changes in the temperature of the air entering the car through the ventilation grilles within a wide range. At the same time, the outside air can be heated, cooled or directed into the car without changing the temperature.

• Blue Zone (A): Cold air
• Red zone (B): warm air

Fan mode switch

The switch is designed to regulate the fan speed. There are four operating positions of the switch, which correspond to four stages of fan speed. The amount of air entering the passenger compartment can be increased by switching the fan to a higher speed. To ensure comfortable conditions in the passenger compartment, the fan must be turned on while the car is moving.

Air distribution regulator

The regulator allows you to set the desired mode of distribution of air entering the cabin. The air distribution regulator handle can be in any of five positions, indicated by the corresponding symbols:

• upper zone ventilation;
• two-level ventilation;
• lower zone ventilation;
• ventilation of the lower zone and blowing of glass;
• glass blowing.

Direction of air flow depending on the position of the regulator

Position (upper zone ventilation)



Position (two-level ventilation)

Air enters the cabin simultaneously through the central and side ventilation grilles, and is also directed through the lower ventilation openings to the foot area of the front passenger and driver.





Position (lower zone ventilation)

Air mainly flows through the lower vents into the footwell of the front passenger and driver. A small amount of air is used to blow air onto the windshield and side windows.



Position (ventilation of the lower zone and blowing of glass)

Air flows through the lower vents into the footwells of the front passenger and driver. At the same time, air is directed through the upper vents and grilles to blow air onto the windshield and the side windows of the front doors.





Position (glass blowing)

The air is directed to the windshield defroster nozzles and the ventilation grilles for the side windows of the front doors.

Air recirculation mode regulator

The ventilation, heating and air conditioning system can operate in two modes: normal (with the flow of fresh, outside air into the cabin) and in recirculation mode - when air access to the cabin from outside is stopped. The modes are switched using the air intake regulator.

Your vehicle may have either a push-button or lever-type mode switch.

Regulator options (switch) air recirculation mode

When you press the button, the indicator light will come on and air will begin to circulate in a closed circuit without exchanging with the atmosphere. When you press the button again, the recirculation mode will turn off, the indicator will go out and outside air will begin to flow into the car.

If the switch is designed as a lever control, to select the mode of outside air intake into the passenger compartment, move the control lever to the left, and to turn on the recirculation mode (with the cessation of outside air supply) - to the right,

Use the recirculation mode when driving in very dusty areas or in heavy traffic to avoid dust and polluted air entering the car. This mode can also be useful for quickly lowering or raising the air temperature in the car.

Note: turn on this mode for a short time, as the interior becomes stuffy, and the increase in air humidity leads to fogging of the windows, which, in turn, impairs visibility.
