Devices of ensuring comfort
System of automatic heating and air conditioning (ACC)
The control unit (To/in) is presented by heating and air conditioning systems on an illustration. On the display located over the block, information on the current parameters of these systems is displayed.
The control unit and the display of systems of heating and To/in
For achievement of the best result from ACC system it is necessary to close all windows and the roof hatch. Air gets through a lattice of a fairing of a windscreen and gets to salon, passing through the filter and if the heater, through a heater radiator is included. Air leaves salon through apertures in the back shelf, and then through lattices on the right and at the left before a rear bumper.
The ACC system 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 work of system the following sensors are used:
Arrangement of sensors of system of automatic heating and To/in
For supply of air in salon deflectors by means of which it is possible to regulate the direction and intensity of an air stream are used. Maximum efficiency of system is reached at completely open deflectors.
Handle of adjustment of the direction and regulator of intensity of an air stream
The salon of the car is divided into 2 temperature zones: place of the driver and place of passengers. The system of automatic heating and To/in allows temperature regulation in a range from 15 to the 27th hail. Besides, there are following modes:
In the HI mode:
In the LO mode it is provided:
On the party of the passenger it is possible to choose the HI or LO mode only if the same choice is made on the party of the driver.
Description of buttons of management of ACC system
Switch of heating of back glass and external mirrors
Heating of back glass and external rear-view mirrors copes manually. Disconnect heating at once as soon as in it there is no need.
Switch of a mode of air circulation
Supply of external air is regulated automatically, providing optimum cooling, but can join/be switched off also manually. The mode of circulation does not change qualitatively composition of air, and it can be included not to allow penetration into salon of unpleasant smells.
Buttons of adjustment of speed of rotation of the fan
Buttons of management of air distribution
Single pressing of the button
Mode обдува glasses
At inclusion manually a mode обдува glasses the zapotevaniye is removed from all glasses (the air stream to back lateral windows is blocked) because:
Having blown in glasses it is included till that time, the new choice, however function of heating is not made yet is disconnected automatically in 5-10 minutes.
Double pressing of the button
Air goes to a windscreen without increase in speed of rotation of the fan and without heating inclusion. For return to earlier made installation press the AUTO button.
By pressing of buttons for inclusion of the combined modes of distribution of air on the display there are corresponding pictograms. The direction of streams of air in various modes is specified on illustrations.

Start in cold weather
The ACC system at first chooses a mode of heating of glasses, the maximum heating and low speed of the fan. With engine temperature increase air goes to feet and speed of the fan increases.
When the temperature in salon reaches the programmed value, speed of the fan decreases and occurs having heated up to automatically certain levels.
System start in hot weather
The ACC system chooses supply of air to deflectors on the dashboard with high speed of the fan and turns on the To/in compressor if the ECON button is not pressed.
If the temperature of air exceeds the 30th hail., approximately through 45 with the circulation mode if the system needs it for achievement of the chosen temperature can join. When the temperature in salon comes nearer to programmed, speed of the fan decreases to automatically certain level.
Programming of I
It is possible to program ACC system so that it joined with the installations chosen manually.
Programming of II
Programming of II is carried out at deduction of the ECON button, the button of a mode of circulation, or the button of heating of back glass until the corresponding symbol on the display not мигнёт 4 times and will not be distributed a sound signal.
The description of the functions joining at activation of the program II, is provided in the description of the corresponding buttons.
Residual heating of salon
On some models with V6 engines the salon heating system from residual heat of the engine can be established.
The system works at OZh temperature above the 40th hail and at the switched-off ignition.
