2.4.1. Systems of heating, ventilation and air conditioning

At the correct use of opportunities of systems of heating, ventilation and air conditioning in interior of the car comfortable conditions of stay are provided and fogging of glasses is excluded.


Control of deflectors of ventilating grates


Adjustment by a deviation of the air stream given to salon through the central and side air ducts of the dashboard

Adjustment of the direction and intensity of air supply through nozzles of the central and side air ducts of the dashboard is carried out by means of special wheel regulators, and also by deployment actually of assemblies of deflectors (see an illustration above). At the same time to situation there corresponds the closed condition of a nozzle, and to situation — open.

Control panel of functioning of systems of heating, ventilation and air conditioning

Air conditioning system can be activated only at the working engine.


In hot weather do not leave in the locked interior of the car of pets, children and sick adults!
In order to avoid a stagnation of air do not include for a long time the mode of the closed circulation!


The automatic mode of functioning To/in (climate control)


Coolings / drainages of the air (AUTO) given to salon

In this mode the air conditioning system will maintain constant temperature in interior of the car, at the same time exercising speed control of functioning of the fan and the direction of distribution of an air stream.

Press the AUTO button on the control panel (see the illustration Control Panel of Functioning of Systems of Heating, ventilation and air conditioning) — on the screen of the display the inscription of the corresponding content has to be highlighted.

By means of the switch of the choice of temperature condition choose temperature which the system will have to support.

The most comfortable temperature around 24 °C is considered.

Further air conditioning system will begin to maintain automatically temperature in interior of the car at the set level, carrying out at the same time necessary corrections of intensity and the direction of air supply.


Mode of economic heating of salon (ECON)

The ECON mode is not intended for removal from condensate glasses.

This mode is used only for warming up of the air given to salon.

 PERFORMANCE ORDER

  1. Press the ECON button on the system control panel (see the illustration Control Panel of Functioning of Systems of Heating, ventilation and air conditioning) — on the screen of the display the inscription of the corresponding content has to be highlighted.
  2. By means of the switch of the choice of temperature condition (see in the same place) choose temperature which the system will have to support. In case of need also intensity and the direction of air supply will be automatically corrected.

Do not expose temperature lower than temperature of external air, otherwise serviceability of functioning of system will be broken.


The removal mode from condensate glasses

 PERFORMANCE ORDER

  1. Press the DEF button on the control panel (see the illustration Control Panel of Functioning of Systems of Heating, ventilation and air conditioning) — on the screen of the display the inscription of the corresponding content has to be highlighted.
  2. By means of the switch of the choice of temperature condition choose the required temperature.
  3. For removal of hoarfrost or condensate from the outer side of glasses choose the maximum high-speed mode of functioning of the fan of a heater by means of the switch.

The choice of the DEF mode at a temperature of external air — 2 °C gives to automatic activation of air conditioning system and shutdown of the mode of the closed circulation above, - for the purpose of acceleration of process of removal of condensate external air will begin to move in salon.

  1. As soon as glasses are purified, press the AUTO button for return of system to the automatic mode of functioning.


Manual control mode


Choice of the high-speed mode of the fan

Switching of the high-speed modes of the fan is made by means of the switch located in the right top corner of the control panel.

For return to the automatic mode of functioning of system press the AUTO button.


Choice of the mode of air circulation

The choice of the mode of air circulation in salon is carried out by means of the button — activation of the mode of the closed ventilation leads to highlighting on the screen of the display of the corresponding pictogram. Repeated pressing of the same button allows to resume giving in salon of fresh external air.

The mode of the closed circulation usually is chosen at the movement in strongly dusty or gas-polluted area, and also in case of need a bystry ostuzheniye of air in salon the conditioner.

At long use of the mode of the closed circulation there is an air stagnation in interior of the car.


Choice of the direction of distribution of air

The choice of the direction of distribution of air is carried out by means of the push-button MODE switch (see the illustration Control Panel of Functioning of Systems of Heating, ventilation and air conditioning) on the control panel of functioning of system — on the screen of the display the corresponding symbols will be serially highlighted.

Air supply is carried out only on front level via deflectors of the central and side air ducts of the dashboard.

Air supply goes on front level and to foot wells.

Air supply is carried out only in foot wells.

Air moves on front level, in foot wells and on having blown in a windshield.


Shutdown of system

For shutdown of system press the OFF button (see the illustration Control Panel of Functioning of Systems of Heating, ventilation and air conditioning).


Councils for use of systems of ventilation, heating and air conditioning

At the cold engine and low temperature of external air air supply in foot wells can be blocked for the period from 0 to 126 seconds — as soon as cooling liquid gets warm, blocking has to be removed automatically.

Maintenance of temperature in salon at the set level is carried out due to its monitoring by means of the sensor which is built in the dashboard — do not put on the panel in a sensor installation site any objects.


Saloon filter

The saloon filter is intended for cleaning of the car of external air given to salon of dust, pollen, dirt, etc. Replacement of the filtering element of the saloon filter has to be made according to the Schedule of routine maintenance of the car (see the Head Routine maintenance).

Sign of pollution of the filtering element of the saloon filter is noticeable decrease in intensity of air supply, and also a legkozapotevayemost of glasses at the working heater or the air conditioning system.
