General information
The vehicles in question are equipped with an HVAC system with the possibility of automatic control.
Air is taken in through the windshield fairing grille and enters the passenger compartment, passing through the filter and, if the heater is on, through its radiator. Keep the windshield fairing grille free of leaves and other debris, and replace the cabin air filter periodically to get the most out of your ventilation system.
Deflectors are designed to adjust the direction of air flow in the cabin (two side, two center front and two center back). Between the central deflectors, an additional regulator of the temperature of the air coming from them is installed. When the rear vents are closed, air is supplied only through the front vents. When the front deflectors are closed, air is supplied to the windshield.
К/В works only at the working engine and at temperature of air above 5°C. On some models

Independent ventilation system
This system uses the HVAC fan to ventilate the passenger compartment and lower the temperature in the passenger compartment when the vehicle is parked. The independent ventilation system is controlled via the multifunctional display (see Section Comfort devices).
Avoid turning on the independent ventilation system twice while the car is parked to avoid draining the battery.
Heated rear window switch
The switch is equipped with a built-in light indicator for turning on the heating. Turn on the heating to remove condensation and frost from the rear window. The heating switches off automatically after a certain time after it is turned on, however, if the desired result is achieved before this time, turn off the heating manually. While the indicator in the switch is lit, the heating operates at maximum power, and after the indicator is turned off, it operates at a reduced power for some time before the automatic shutdown of the heating.
Turn on the heated rear window with the engine running to prevent battery discharge.
Optimal system settings
It is recommended to use automatic HVAC system control mode. To do this, press the AUTO button (General view of the HVAC system control unit), select the desired temperature (recommended 22°C) and direct the air flow from the center vents so that it blows over the occupants, but does not hit them directly. The following describes how to use the manual adjustments of the HVAC system.
To select one of the defined air supply modes (to the face, to the feet or to the windshield) press the appropriate switch (General view of the HVAC system control unit). In this case, the automatic mode is switched off.
For a quick removing frost and condensation from windows press the defrost switch (General view of the HVAC system control unit).
For on/off K/V press the appropriate switch (General view of the HVAC system control unit). When the A/C is running, the air entering the passenger compartment is cooled and dehumidified. This speeds up the removal of condensate from the windows at high humidity.
The moisture taken from the air during A/C operation condenses and descends from under the car, so the presence of a puddle under the car after it has been parked with the A/C turned on is a normal phenomenon. To get the most out of the A/C system, close the windows and sunroof when using it.
For maximum cooling air supplied to the passenger compartment, press the corresponding switch (General view of the HVAC system control unit), when the ignition key is in the position starting from «1». If this switch is pressed when the key is in the «0», turns on residual heat mode engine. This mode is only available when the engine is off and the engine is warm, when the battery has sufficient charge and the outside temperature is less than 15°C.
By successive pressing automatic air circulation switch you can switch between automatic mode (the circulation mode switches on and off automatically, depending on the quality of the outside air, while the indicator on the left side of the switch lights up), supply ventilation mode (outside air constantly enters the cabin, while the indicators do not light up) and recirculation mode (outside air is not supplied to the passenger compartment, while the indicator on the right side of the switch is on).
When equipped with a multifunction steering wheel, switch between automatic mode and fresh air mode using the switch located on it.
Circulation mode should be used when driving on dusty roads or in heavy traffic to prevent dust, odors and exhaust gases from entering the passenger compartment. In addition, the circulation mode allows you to significantly accelerate the decrease in the temperature in the cabin when using A/C.
Do not turn on the air circulation mode for a long time, because. at the same time, the air in the passenger compartment becomes stale, and condensation appears on the windows.
With help temperature and air supply switches separately for the left and right parts of the passenger compartment, they can be set to different temperatures and air supply intensity. These parameters are shown on the display (General view of the HVAC system control unit). When you press the button to reduce the intensity of the air flow at its minimum value, the fan, heater and A/C are turned off and the circulation mode is selected. To return to normal operation of the HVAC system, press any button on the HVAC control unit.
A/C system in the rear
With the corresponding equipment, a control unit for the K / V system in the rear of the passenger compartment is installed in the rear of the center console.
