System of automatic heating and air conditioning (ACC)
The general information
The block of management (К/В) is presented by heating and air conditioning systems on an illustration. On the display located over the block, the information on current parametres of these systems is displayed.
The block of management and the display of systems of heating and К/В
For achievement of the best result from system ACC it is necessary to close all windows and the roof hatch. Air gets through a lattice обтекателя 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 a back shelf, and then through lattices on the right and at the left before a back bumper.
System ACC 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 system work following gauges are used:
Arrangement of gauges of system of automatic heating and К/В
For air giving in salon are used дефлекторы with which help it is possible to regulate a direction and intensity of an air stream. Peak efficiency of system is reached at completely opened дефлекторах.
The handle of adjustment of a direction and regulator of intensity of an air stream
The car salon is divided into 2 temperature zones: a place of the driver and a place of passengers. The system of automatic heating and К/В supposes temperature regulation in a range from 15 to 27 hailstones. Besides, there are following modes:
In a mode HI:
In a mode LO it is provided:
On the party of the passenger it is possible to choose a mode HI or LO only if the same choice is made on the party of the driver.
The description of buttons of management of system ACC
The 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 necessity.
The switch of a mode of air circulation
Giving of external air is regulated automatically, providing optimum cooling, but can vkljuchatsja/be switched off also manually. The mode of circulation does not change qualitatively air structure, and it can be included not to admit 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 запотевание leaves from all glasses (air stream to back lateral windows is blocked) because:
Having blown in glasses it is included till that time, the new choice, however heating function is not made yet 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 button "AUTO".
By pressing of buttons for inclusion of the combined modes of distribution of air on the display there are corresponding pictogrammes. The direction of streams of air in various modes is specified on illustrations.

Start in cold weather
System ACC at first chooses a mode of heating of glasses, the maximum heating and low speed of the fan. With rise in temperature of the engine 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
System ACC chooses air giving to дефлекторам on the panel of devices with high speed of the fan and includes compressor K/V if button "ECON" is not pressed.
If the air temperature exceeds 30 hailstones., approximately through 45 with the circulation mode if the system requires 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.
It is possible to program system ACC so that it joined with the installations chosen manually.
Programming II is carried out at deduction of button "ECON", the button of a mode of circulation, or the button of heating of back glass until the corresponding symbol on the display will not blink 4 times and the sound signal will not be distributed.
The description of the functions joining at activation of the program II, is resulted in the description of corresponding buttons.
Residual heating of salon
On some models with engines V6 the heating system of salon from residual heat of the engine can be established.
The system works at temperature ОЖ above 40 hailstones and at the switched off ignition.
