1.5.1. Heating and ventilation system

The description
The heating and ventilation system maintains necessary temperature in car salon.
The left display serves for indication of the set temperature on the party of the driver, and right for indication of the set temperature on the party of the forward passenger.
All modes of the conditioner join and switched off by pressing of keys. At the included mode in a corresponding key the diode burns.

The filter of catching of harmful substances
The filter of catching of harmful substances (the filter of catching of the weighed microparticles) substantially reduces quantity of a dust containing in external air, pollen, gases etc.
Filtering element of the filter of catching of harmful substances change according to the service book for the purpose of prevention of loss of capacity of system of ventilation and heating.
At premature deterioration of the filter as a result of car operation in zones with strong air pollution more frequent can be demanded, than предусмотренно by the service book, replacement of a filtering element.

ATTENTION
For traffic safety it is important, that all windows were free from snow, ice and a moisture. Only in this case good visibility conditions are guaranteed. Familiarise with instructions for use system отпопления and ventilation, and also otpotevanija/heating of glasses.

THE NOTE
For normal work of system of heating and ventilation it is important, that the air inlet before a windscreen was not hammered by snow, ice or foliage.
Arriving through приточные channels and distributed then on all salon air leaves through exhaust cracks under back glass. Therefore do not close their subjects of clothes, etc. things.

Temperature regulation
The temperature in salon can be set independently for the party of the driver and the forward passenger.

The party of the driver

Fig. 1.134. Controls heating and ventilation system: And – keys of regulation of temperature on the party of the driver; In – in heating (having blown) in glasses; With – fan keys; D – keys of distribution of air; E – keys of regulation of temperature on the party of the forward passenger; F – a key рециркуляции air; G – deenergizing of system of heating


Pressing of keys «+» or «–» establish the necessary temperature (fig. 1.134).

The party of the forward passenger
Pressing of keys «+» or «–» establish the necessary temperature (fig. 1.134).
Actual value of temperature is displayed in the form of segment indication of the display located over keys.
In a mode maximum теплопроизводительности on the display indication "MOVE" is deduced. At is minimum established temperature on the display indication «MIN» is deduced.
Switching of value of temperature for the driver on the party of the forward passenger and on the contrary occurs more long simultaneous pressing of keys «+» or «–» on the party of the driver or the forward passenger. The new established temperature is deduced on corresponding the display. There is a return possibility to earlier established temperature. For this purpose the driver or переднеий the passenger should establish anew temperature on the display.

Having warmed (thawing) of glasses
As fast as possible thaws and moistens wind and lateral glasses.
For inclusion press a key.
For deenergizing again press the same key.
The temperature is regulated automatically. The maximum giving of air is carried out mainly on channels 1 and 2.
The mode рециркуляции air is switched off by pressing of a key.

Correction of frequency of rotation of the fan
For installation of actual frequency of rotation of the fan (quantity of air) press keys «+» or «–».
The quantity of air can be regulated at will. Actual frequency of rotation of the fan is displayed in the form of segment indication of the display located over keys.
It is recommended at movement with small speed always to include on low power the fan.
For hit prevention in salon of polluted external air (unpleasant smells) include pressing of a key a mode рециркуляции.

Air distribution
Probably both separate, and the combined manipulation keys. Three keys have following appointment. Numbers correspond воздуховыпускным to devices.

Air giving to glasses
All expense of air is realised on channels 1 and 2. Unlike a mode of heating the quantity of air does not change.

Air giving from outside panels of devices
All expense of air is realised with giving through lattices of 3 and 4 panels of devices, and also the central console behind.

Air giving in space for feet
All expense of air is realised through приточные channels 5 and vozduhovy-pusknye devices under forward seats.

THE NOTE
In the resulted positions воздухораспределителя some leak of air through other lattices always takes place.

Mode рециркуляции
In a mode рециркуляции hit in salon of the car of polluted external air is substantially prevented.
For mode inclusion press a key.
For mode deenergizing again press a key the same key or press a key.
In a mode рециркуляции air access is from the outside blocked, and its volume is distributed in salon on a circle. The mode рециркуляции is recommended to be included at movement through a tunnel or in a transport stopper for prevention of hit of external air in salon.

ATTENTION
Movement in a mode рециркуляции should not be too long-term since in salon fresh air does not arrive and glasses can mist over.

THE NOTE
For the safety reasons, at the pressed key the mode рецикуляции air is impossible.

Deenergizing of the fan of a heater «OFF»
Press a key «OFF». The fan is switched off and access of external air is blocked.
Besides, the fan again joins repeated pressing of a key «OFF», and also pressing of keys of the fan or temperature regulation.
