2.4.1. System of automatic heating and air conditioning (ACC)
The control unit of systems of heating and air conditioning (To/in) is presented 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 it is necessary to close all windows and the hatch of a roof from the ACC system. Air gets through a lattice of a fairing of a windshield and gets to salon, passing through the filter and if the heater, through a heater radiator is included. Air comes out salon through apertures in the back shelf, and then through lattices before a rear bumper on the right and at the left.
The ACC system 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 following sensors are used:
- Sensor of temperature of external air;
- Temperature sensor in salon;
- Sunlight sensor;
- Two sensors of temperature of air mix (in the lower forward deflectors).

Do not cover the sunlight sensor since at the same time the system of automatic heating and air conditioning can work not correctly. |
For air supply 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.

Adjustment of temperature
The interior of the car is divided into 2 temperature zones: driver's seat and places of passengers. The system of automatic heating and To/in allows regulation of temperature in the range from 15 to 27 a hail. Besides, there are following modes:
In the HI mode:
- The maximum heating is provided;
- Air is directed to a windshield and to legs;
- If the circulation mode was chosen, it is disconnected;
- The fan works at the maximum speed.
In the LO mode it is provided:
- The maximum cooling (at inclusion of the ECON mode joins To/in) is provided;
- Air is directed to the dashboard;
- The mode joins;
- The fan works at the maximum speed.
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 the ACC system
AUTO
- Temperature, air distribution, turns of the fan and air supply are regulated automatically;
- The K/V compressor is switched off at temperature drop a lower than 0th hail. also joins at excess the 5th hail.;
- At start of the engine at an external temperature from 0 to 5 hail. To/in it is included;
- By pressing the AUTO button all manual adjustments are cancelled;
- By repeated pressing the AUTO button on the display automatically set installations are displayed;
- At start of the engine the ACC system works in the AUTO mode, irrespective of the installed program.
ECON
- The compressor is switched off, the arriving air is not cooled;
- Temperature, distribution of air and turns of the fan are regulated automatically.
|
|
At deduction of this button (programming of II) To/in joins at achievement of external temperature more 13th hail. |
OFF
- The ASS system (the fan, To/in and a heater) is switched off;
- Distribution of air is fixed in urgent situation;
- The mode of circulation can be chosen manually;
- By repeated pressing the AUTO button the ACC system passes into the automatic mode;
- By repeated pressing the OFF button the system comes back to control mode manually.
Switch of heating of back glass and external mirrors
Heating of back glass and external rear-view mirrors copes manually. Turn off heating at once as soon as in it there is no need.
|
|
Heating is turned off automatically in 2-10 minutes depending on temperature of external air or if tension of the battery falls lower than 10 Century. The ASS system can be programmed so that heating will automatically join if at the same time temperature of external air is lower the 5th hail., and temperature in salon is lower the 10th hail (see programming of II). |
Air circulation mode switch
Supply of external air is regulated automatically, providing optimum cooling, but can also join/be switched off 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.
|
|
At deduction of this button (programming of II) circulation joins at a speed of car lower than 10 km/h and is switched off at a speed below 30 km/h, except for that case when the ECON function is programmed according to the program II. |
Buttons of adjustment of speed of rotation of the fan
- By pressing these buttons the speed of rotation of the fan gradually changes;
- At inclusion of ignition the fan works at small speed until the engine is not started;
- If the speed of the 0 fan is chosen, the K/V compressor is switched off and on the display the inscription "ECON" appears.
Buttons of management of air distribution
Single pressing of the button
Mode of an obduv of glasses
|
|
At inclusion manually of the mode of an obduv of glasses fogging is removed from all glasses (the air stream to back side windows is blocked) because:
- The fan works at high turns;
- Air goes to deflectors;
- Temperature is regulated in the normal mode;
- The mode of circulation is turned off;
- Heating of back glass and external mirrors joins.
Having blown in glasses it is included till that time, a new choice is not made yet, however function of heating is turned off automatically in 5-10 minutes.
Double pressing of the button
Air goes to a windshield without increase in speed of rotation of the fan and without heating inclusion. For return to earlier made installation press the AUTO button.
Other buttons
By pressing buttons for inclusion of the combined modes of distribution of air on the display the corresponding pictograms appear. The direction of streams of air in various modes is specified on illustrations.

Start in cold weather
The ACC system at first chooses the mode of heating of glasses, the maximum heating and low speed of the fan. With temperature increase of the engine air goes to legs and the speed of the fan increases.
When temperature in salon reaches the programmed value, the speed of the fan decreases and occurs having heated to automatically certain levels.
Start of system in hot weather
The ACC system chooses air supply to deflectors on the dashboard with a high speed of the fan and turns on the K/V compressor if the ECON button is not pressed.
If temperature of air exceeds the 30th hail., approximately through 45 with the circulation mode can join if the system needs it for achievement of the chosen temperature. When temperature in salon comes nearer to programmed, the speed of the fan decreases to automatically certain level.
Programming of I
It is possible to program the ACC system so that it joined with the installations chosen manually.
|
|
For entering ignition has to be included in memory of the chosen installations, at least, 10 minutes. |

Programming of II
Programming of II is carried out at deduction of the ECON button, circulation mode button, or button of heating of back glass until the corresponding symbol on the display does not blink 4 times and the sound signal will not be distributed.
|
|
Ignition has to be included. |
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 heating system of salon from residual heat of the engine can be installed.
The system works at OZh temperature above the 40th hail and at the switched-off ignition.
