Air enters the passenger compartment through the air intake grille located outside under the windshield of the car. If necessary, it is possible to turn off the outside air intake. Air is released through special openings in the rear wall of the luggage compartment - to maintain comfortable microclimate conditions in the cabin, do not block them with luggage.
Heating of the air flow in the ventilation and heating system is achieved by passing air through the heater heat exchanger, which is connected to the engine cooling system parallel to the main radiator.
Note: Diesel models can be equipped with an additional Ouickneat electric heating system for faster heating of the air in the cabin (until the engine warms up).
In the air conditioning (A/C) system, cooling and dehumidification of air occurs by means of a special refrigerant charged into this system, which circulates in a separate closed circuit when the compressor is activated. (see Chapter 3)

Depending on the configuration, the system is equipped with a carbon or regular air filter for the intake tract, which protects the interior from dirt, dust and pollen. For maximum efficiency of the system and maximum comfort in the interior, the filter should be replaced regularly during the next scheduled maintenance of the car (see Chapter 1 Section 19).
Note: The filter must be replaced without waiting for the next service if the intensity of the air flow supplied to the passenger compartment noticeably decreases or the windows begin to fog up slightly while the heater or air conditioner is operating.
