Devices of ensuring comfort

System of automatic heating and air conditioning

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

1 — the temperature Index
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 — a temperature Regulator
6 — the switching off Button

7 — the Button обдува a windscreen
8 — the Switch of a mode of air circulation
9 — the To/in Switch
10 — the Regulator of speed of rotation of the fan
11 — the Button of a choice of a 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 an inscription of "BRIGHTNESS", located on the control panel an audiosystem (see an illustration Governing bodies and audiosystem control). The system of automatic heating and To/in independently selects the working parameters for maintenance in salon of the car of the established temperature. At modification manually in one of parameters by means of the corresponding switch or a regulator, this parameter is not regulated any more by automatic equipment while other parameters continue to steal up automatically. For system work the ignition key should be in the situation "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 necessary to change regularly the salonny filter (see. The section Check and replacement of the salonny filter of a heater and To/in).

Below the description of the modes established manually by means of the corresponding regulators and switches is provided.

Button of a choice of a mode of distribution of air

The direction of air streams from deflectors

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

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

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

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

Switch of a mode of air circulation

This switch opens and closes access of external air to car salon. Inclusion of a mode of circulation is made by single pressing the switch. Thus should light up To/l, located over the switch. For switching off of a mode of air circulation press the switch once again, To/l should go out. The switched-off mode of circulation is a usual mode and it is recommended for continuous use.

The mode of circulation is intended for an otsechka of intake of external air in car salon for the purpose of temporary intensive heating or salon cooling. In addition the mode of air circulation can be used for hit prevention in salon of dirty air (for example, at movement on the filled with smoke site of the road).

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

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

To/in switch

Compulsory inclusion To/in is made by single pressing this switch. Thus should light up To/l, located over the switch. For switching off To/in press the switch once again, To/l should 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 обдува windscreen

For removal of a zapotevaniye of a windscreen from within it is necessary to include having blown in a windscreen, having pressed this button. Thus should light up To/l, located over the switch. For removal of a zapotevaniye of a windscreen outside, and also for hoarfrost removal from a windscreen, establish the maximum temperature and speed of rotation of the fan and include having blown in a windscreen.

At inclusion обдува a windscreen automatically joins To/in and the mode of a fence of external air is established. By repeated pressing the switch обдува a windscreen earlier established mode gets out.

Temperature regulator

For fast cooling/heating of salon turn a temperature regulator so that on the display there was an inscription according to «MAX. HOT» or «MAX. COLD». In the second case the air circulation mode automatically gets out.
