2 — the Indicator of speed of rotation of the fan
3 — the Indicator of distribution of air streams
4 — the automatic control Switch
5 — a temperature Regulator
6 — the deenergizing Button

7 — the Button обдува a windscreen
8 — the Switch of a mode of air circulation

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 the information on current parametres of systems is displayed. Brightness of the display can be regulated by means of the buttons designated by an inscription «BRIGHTNESS», located on the control panel an audiosystem (Controls and the audiosystem control see an illustration). The system of automatic heating and К/В independently selects the working parametres for maintenance in salon of the car of the established temperature. At modification manually in one of parametres by means of the corresponding switch or a regulator, this parametre is not regulated any more by automatics while other parametres continue to steal up automatically. For work of system the ignition key should be in position «ON» or «ACC».

For inclusion of system of automatic heating and К/В press the switch of automatic control and by means of the corresponding handle (5) expose necessary temperature. For system deenergizing press the deenergizing button («OFF»).

For reception of the maximum return from systems of heating and К/В it is necessary to change regularly салонный the filter (the Section Check and replacement салонного the filter of a heater and К/В see).

The description of the modes established manually by means of corresponding regulators and switches is more low resulted.

The button of a choice of a mode of distribution of air

Direction of air streams from дефлекторов

By each pressing the given button occurs switchings between the modes listed more low (the corresponding pictogramme is displayed on the multipurpose display).

At level of the person. The air stream is directed basically to the person through дефлекторы to the panel of devices.
At level of the person and feet. The air stream goes to feet and to the person through дефлекторы to panels of devices and in a floor.
At level of feet. Air most part arrives to feet through дефлекторы in a floor.
At level of feet and windscreen heating. The most part of an air stream arrives to feet and a windscreen through дефлекторы in a floor and before a windscreen.

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

Regulation of an air stream from lateral дефлектора.
Regulation of an air stream from central дефлекторов.

The switch of a mode of air circulation

The given switch opens and closes access of external air to car salon. Inclusion of a mode of circulation is made by unitary pressing the switch. Thus should light up К/Л, located over the switch. For deenergizing of a mode of air circulation press the switch once again, К/Л should go out. The switched off mode of circulation is a usual mode and it is recommended for constant use.

The circulation mode is intended for отсечки receipts of external air in salon of the car for the purpose of time intensive heating or salon cooling. Besides it the air circulation mode can be used for hit prevention in salon of dirty air (for example, at movement on the filled with smoke site of road).

Long use of a mode of circulation leads to increase of humidity and спёртости air in salon of the car and, hence, to запотеванию glasses and to visibility deterioration.

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

Switch K/V

Compulsory inclusion К/В is made by unitary pressing the given switch. Thus should light up К/Л, located over the switch. For deenergizing К/В press the switch once again, К/Л should go out. Blinking К/Л testifies to malfunction of compressor K/V.

К/В will not join, if temperature of external air no more than 0 hailstones. For economy of fuel do not use К/В needlessly.

The switch обдува a windscreen

For removal запотевания a windscreen from within it is necessary to include having blown in a windscreen, having pressed on the given button. Thus should light up К/Л, located over the switch. For removal запотевания a windscreen outside, and also for removal of hoarfrost 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 К/В 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 accordingly «MAX. HOT» or «MAX. COLD». In the second case the air circulation mode automatically gets out.
