Devices of ensuring comfort

System of automatic heating and air conditioning

Governing bodies and control of systems of heating and To/in

1 — the Index of temperature
2 — the Indicator of speed of rotation of the fan
3 — the Indicator of distribution of air streams
4 — the Switch of automatic control
5 — temperature Regulator
6 — the switching off Button

7 — the Button of an obduv of a windshield
8 — the air circulation mode Switch
9 — the K/V Switch
10 — the Regulator of speed of rotation of the fan
11 — the Button of the choice of the mode of distribution of air
12 — the Switch of heating of glass of a door of a back and external rear-view mirrors

On the multipurpose display information on the current parameters of systems is displayed. Brightness of the display can be regulated by means of the buttons designated by the inscription "BRIGHTNESS", located on the control panel of the audio system (see an illustration Governing bodies and control of the audio system). The system of automatic heating and To/in independently selects the working parameters for maintenance in interior of the car of the established temperature. At modification manually of one of parameters by means of the corresponding switch or the regulator, this parameter is not regulated any more by automatic equipment while other parameters continue to be selected automatically. For work of system the ignition key has to be in the provision of "ON" or "ACC".

For inclusion of system of automatic heating and To/in press the switch of automatic control and by means of the corresponding handle (5) expose necessary temperature. For switching off of system press the button of switching off ("OFF").

For receiving the maximum return from systems of heating and To/in it is regularly necessary to change the saloon filter (see the Section Check and replacement of the saloon filter of a heater and To/in).

The description of the modes set manually by means of the corresponding regulators and switches is given below.

Button of the choice of the mode of distribution of air

The direction of air streams from deflectors

By each pressing this button occurs switchings between the modes which are listed below (the corresponding pictogram is displayed on the multipurpose display).

At the level of the person. The air stream is directed generally to the person via dashboard deflectors.
At the level of a face and legs. The air stream goes to legs and to the person via deflectors to dashboards and in a floor.
At the level of legs. The most part of air arrives to legs via deflectors in a floor.
At the level of legs and heating of a windshield. The most part of an air stream arrives to legs and a windshield via deflectors in a floor and before a windshield.

Distribution of air streams can be regulated also by means of deflectors, turning and closing them.

Regulation of an air stream from the side deflector.
Regulation of an air stream from the central deflectors.

Air circulation mode switch

This switch opens and closes access of external air to interior of the car. Inclusion of the mode of circulation is made by single pressing the switch. At the same time has to light up To/L, located over the switch. For switching off of the mode of air circulation press the switch once again, To/L has to go out. The switched-off mode of circulation is the usual mode and is recommended for constant use.

The mode of circulation is intended for a cut-off of intake of external air in interior of the car for the purpose of temporary intensive heating or cooling of salon. In addition the mode of air circulation can be used for prevention of hit in salon of dirty air (for example, at the movement on the smoke-filled section of the road).

Long use of the mode of circulation leads to increase in humidity and a spyortost of air in interior of the car and, therefore, to fogging of glasses and deterioration in visibility.

Inclusion of the mode of circulation can automatically happen at excessive increase in temperature of the cooling liquid (CL), is a normal phenomenon. After cooling of OZh earlier chosen mode is set.

K/V switch

Compulsory inclusion To/in is made by single pressing this switch. At the same time has to light up To/L, located over the switch. For switching off To/in press the switch once again, To/L has to go out. The blinking To/L testifies to malfunction of the К/В compressor.

To/in will not join if temperature of external air no more than 0th hail. For economy of fuel do not use To/in needlessly.

Switch of an obduv of a windshield

For removal of fogging of a windshield it is necessary to include from within having blown in a windshield, having pressed this button. At the same time has to light up To/L, located over the switch. For removal of fogging of a windshield outside, and also for removal of hoarfrost from a windshield, establish the maximum temperature and speed of rotation of the fan and include having blown in a windshield.

At inclusion of an obduv of a windshield automatically joins To/in and the mode of an intake of external air is set. By repeated pressing the switch of an obduv of a windshield earlier set mode is chosen.

Temperature regulator

For bystry cooling / heating of salon turn temperature regulator so that on the display the inscription according to "MAX appeared. HOT" or "MAX. COLD". In the second case the air circulation mode automatically is chosen.
