Use of residual engine heat/air conditioner cold
The heating/cooling of the passenger compartment can continue for some time after the engine has been stopped by using the accumulated residual heat/cold. The mode is activated when the ignition is off by pressing the button «AUTO» on the control panel (see illustration 18.9), the control LED integrated in the button should light up, the display briefly shows Residual air conditioning on.
When the mode is activated, the intensity and directions of the air supply are adjusted automatically (usually the minimum fan speed is selected). The duration of the operation of the system depends on the selected temperature settings and the initial temperature of the engine coolant. The mode is turned off by pressing the button again «AUTO» or automatically by a timer signal, as well as a noticeable decrease in the battery charge level.
Windshield blower
If necessary, for example, to quickly clean the windshield from snow, ice and condensate before driving the car, you can quickly activate the windscreen blowing mode by pressing the button on the HVAC control panel - the LED built into the button should light up. At the same time, the system automatically ensures that the heater and fan are switched to maximum performance, and the entire flow of air supplied to the passenger compartment is redirected to blowing the windshield and side windows.
Note: The airflow rate can be increased or decreased using the right control.
To return to automatic mode, you must press the same button or button again «AUTO».
Rear window heating
The rear window heating element is activated using the corresponding button on the system control panel - the control LED built into the button should light up. For more details, see Section 17.
More information on the HVAC system
During the operation of the air conditioner or heater, the passenger compartment windows must be closed. In order for the air temperature in the passenger compartment to quickly reach the set temperature, it is recommended to use the air circulation mode at the initial stage of the system operation, when it is turned on.
Attention: As soon as the temperature reaches the set parameters, do not forget to turn off the circulation mode!
In hot sunny weather, after the car has been parked in the sun for a long time, it is recommended to drive with the windows open for the first two or three minutes of driving and ventilate the interior for faster cooling of the air with the air conditioner. Operation of the A/C system in hot weather can cause condensation to form, the removal of which can lead to moisture dripping under a parked vehicle, which should not be a cause for concern. Before driving, clean the air intake grille of snow, dirt and fallen leaves. To quickly clean the glass from ice and misting, turn on the heater fan at full power.
To keep the components of the A/C refrigeration circuit in working order, run the compressor for a few minutes at least once a month, even if there is no need for air conditioning.
Note: On models equipped with climate control, this procedure is performed automatically while driving, however, at low outside temperatures, when the air conditioner is not activated, the preventive activation of the system must be performed by the driver.
