Comfort



Incoming standard on some models, automated air conditioning system operates only when the engine is running. When Economy Mode (ASoff), the cooling system is not working.

Go to the selected temperature mode is always done with the maximum possible speed.

Slight variations in temperature around the set point explains the influence of solar radiation and temperature fluctuations outside air.

Built-in air inlet tract systems are connected filter protects the interior from the penetration of dust and pollen.

General comments on the functioning of the system K / V

Operation of the system K / V can lead to the formation of condensation under the vehicle - a car parked under the formation of a small puddle in hot weather should not cause concern.

In hot sunny weather before driving ventilate the vehicle interior heated by the sun.

Make sure that the ventilation holes in the space between the back of the shelf and the rear window of the car were open.

In winter, before moving clean the snow from the air intake grille to the windscreen of the car.

In the event of refrigerant leakage operation of K / V is automatically suspended and the system switches to economy mode.

Controls

Air supply to the interior of the vehicle carries the network of air ducts of the ventilation system, equipped with deflectors ending nozzles.

2 - Rotary selection temperature
3 - Rotary direction when air distribution
4 - Button for activating the condensate from glasses
5 - Button groove air circulation

6 - Buttons activate the AUTO mode
7 - Power button Eco Mode
8 - button activation electrical heating rear window
9 - button off the air supply in the rear
10 - air temperature sensor in the cabin

The automatic operation

The automatic operation of the system is the base. To activate, press the AUTO switch the central control panel - will light up the LED built into the button. Selecting the desired temperature is accomplished by rotation of the central rotary control switch (built-in regulator glowing ring segment serves for indicating the selected value).

Turning the knob to the extreme position, marked with blue and red dots on the assembly function of the temperature control switch is turned off.

By assigning a comfortable temperature, press the AUTO button and hold it for at least 3 seconds - the system automatically switches to maintain the selected setting.

Activation of electrical heating rear window can optionally be made manually.

The design of the control system provides for programming base temperature. Turn the rotary knob of the central switch to the selected position to your discretion (eg, 21 ?� C), and then press the AUTO button and hold it down for about 10 seconds.

Adjustment of the set temperature should be made in small steps.

Manual adjustment of intensity and direction of air distribution

The intensity and direction of air distribution can be set manually with the rotary knobs side switches (AUTO mode control LED goes out), - the selected temperature mode is not changed.

The feed rate of air may vary within 5 degrees of speed modes of functioning of the fan.

When installing the air flow rate to zero, the system shutdown is done! The choice of the installation must be carried out only a short time.

Selecting direction of air distribution provides the following options:

The air supply to blow the windshield
The air supply to blow the glass on the front foot level in wells
Air supply to the foot wells and front side air layer through the dashboard
The air supply to the front level

Return to the automatic mode can be performed by pressing AUTO (glowing segments, embedded in a ring of regulators should go out) - make sure of serviceability of activation control LED automatic mode.

Mode condensate from glasses

To quickly remove condensation from the windows, press - Should light mounted in the button controlling the LED. The system will automatically provide maximum heating and fan performance, the air supply to blow the windscreen and side windows (from the side of the nozzle dash, - do not forget to fully open them communicating the nozzle and expand as required rotary deflectors) on and off the air supply to the rear of the cabin.

Adjust all the other plants, except for electrical heating rear window, at the time of activation is blocked.

To disable re enough to click on the same button or the button AUTO.

To remove the condensate from the outer surface of the windshield should select the air supply used to blow glass ( ) And activate the wipers.

Mode closed air circulation

Activation of the closed air circulation is carried out using the bottom left button switch front panel control K / V - should come built-in button control LED. In this mode, disable supply of fresh air into the cabin. This function allows you to prevent the vehicle by a contaminated or unpleasant-smelling air.

Prolonged use of closed circulation, resulting in fogging and increasing closeness air, so it is recommended to include this mode only when necessary and in a relatively short time, for example, when driving on the area with smoke or air pollution. As soon as there is no need to isolate the passenger compartment, fresh air supply should be resumed.

Pressing the switch button allows you to restore the air supply.

There are also automatic shutdown mode closed circulation alarm timer: approximately 30 minutes while the K / B, or after 5 minutes at off K / V.

At high ambient temperatures the activation mode of the closed circulation is done automatically and is not accompanied by the LED on the control button switch.

Economy mode

When Economy mode is carried off the compressor K / V.

To activate the ECO mode, press ACoff central switch - should light mounted in the button controlling the LED.
