At the correct use of opportunities of systems of heating and ventilation in salon of the car comfortable conditions of stay are provided and fogging of glasses is excluded.

If the car upon purchase was not equipped with the air conditioning system, it can be mounted and established in any time, convenient for the owner, at any time install this system on the car, - address on car repair shop of the Subaru company.

 On equipped with system In models usually the saloon filter providing preliminary cleaning of the car of external air given inside is installed. The filtering element is established under the fairing lattice located ahead of a windshield, is made of viscose, to a clearing is not subject and in case of pollution owes replacement. In normal service conditions of the car replacement of the saloon filter has to be made annually, or through each 15 000 km of run.


Detailed information on use and service of systems of heating and air conditioning is stated below (see also Head of the Cooling system, heating).

Air supply in salon of the car

Air supply in salon of the car carries out on a network of the air ducts of system of ventilation terminating in the nozzles equipped with deflectors.

 

Output nozzles of air ducts settle down on the dashboard and in foot wells of salon.

Control of deflectors of the central and lateral air ducts of the dashboard

Deflectors of the central and lateral air ducts of the dashboard are equipped with the special rotary zhalyuziyny lattices allowing to regulate the direction of giving of an air stream both in horizontal and in vertical the planes. Control of deflectors is exercised by means of built in a lattice snuffled ring handles, intensity of air supply through lateral nozzles is regulated by the ring regulator which is built in facing of the deflector.

In the top forward part of the dashboard the central slot-hole nozzles of air supply are located on having blown in a windshield and two lateral in rotary deflectors of an obduv of door glasses. The direction of air supply through slot-hole nozzles is not subject to adjustment. Lateral deflectors can be in case of need deployed so that to provide additional air supply on a windshield for the purpose of acceleration of removal from it of condensate, - do not forget to return deflectors to a starting position (on having blown in lateral glasses) then.


Control panel functioning of systems of ventilation/heating/air conditioning

Hand-operated models functioning To/in

The control panel design is presented by functioning of systems of ventilation/heating/air conditioning on an illustration.

The rotary handle located in the left part of the control panel serves for a choice of temperature condition of functioning of a heater. Blue range of the handle of a scale put on perimeter corresponds to the mode of supply of cool air, red - to the heating mode.

In the central part of the panel the rotary handle of the switch of a choice of the high-speed mode of the fan of a heater is located. The fan functions only at the included ignition (a key in the situation ON). The switch allows to choose one of four possible high-speed modes (from "1" to "4"), and also absolutely to switch-off the fan (situation "0").

On the right the rotary handle of a choice of the directions of distribution of an air stream is located on the panel, having five fixed provisions:

Air supply on front level;
Air supply on front level and in foot wells;
Air supply in foot wells;
Air supply in foot wells and on having blown in a windshield;
Air supply on having blown in a windshield.

In the lower part of the control panel three push-button switches equipped with the built-in control lamps are located. Right from them serves for activation of functioning of the conditioner of air. For shutdown To/in it is necessary to press the switch repeatedly (the control lamp has to go out).

In the middle there is an air ventilation mode switch. Activation of this mode (the control lamp burns) brings to shutdown of giving into salon of fresh air. Repeated pressing the switch button (the lamp does not burn) allows to restore air supply.

 Long use of the closed circulation, especially at the idle conditioner of air, leads to fogging of glasses and increase of a spertost of air therefore it is recommended to include this mode only in case of need and for rather short time, for example, at the movement on the district with the filled with smoke or polluted atmosphere. As soon as need of isolation of salon disappears, supply of fresh air has to be resumed.

Instructions on use of systems of ventilation, heating and air conditioning

Detailed maintenance instructions of systems of heating, ventilation and air conditioning in various climatic conditions are given below. Information how to provide effective ventilation, heating and cooling of air in salon of the car, and also how quickly to remove condensate and hoarfrost from glasses is provided to attention of the reader.

All considered systems function only at the started engine. As a working body for a heater cooling liquid of the engine is used. If the engine is not heated-up up to the normal working temperature, some minutes before in salon warm air starts moving will be required. Operation of the air conditioning system does not depend on temperature of cooling liquid of the engine.

In absolute majority of cases the best efficiency of functioning of the systems providing a comfortable microclimate is reached in the giving mode in salon of external air. Long inclusion of the mode of circulation, especially at the idle conditioner of air, leads to fogging of glasses and increase of a spertost of air therefore it is recommended to include this mode only in case of need and for rather short time, for example, at the movement on the district with the filled with smoke or polluted atmosphere. As soon as need of isolation of salon disappears, giving in salon of fresh air has to be resumed.

External atmospheric air comes to systems of heating and conditioning through the reception lattice located before a windshield and equipped with a fairing. Periodically clean openings of a reception lattice from leaves and the other garbage complicating air passing.

Ventilation of salon of the car

The system of a supply and exhaust ventilation provides a constant exchange of air in salon of the car. The fresh external air arriving through a forward reception lattice circulates on salon and then is removed through the exhaust outlets located near back glass:

a) Turn the air temperature regulator handle counterclockwise against the stop. Check that the conditioner of air was switched off;
b) Install the handle of switching of the directions of air supply in situation. The mode of air circulation has to be switched off;
c) By means of the handle of a choice of the high-speed mode of the fan establish the demanded intensity of air supply in salon of the car.

Cooling of air in salon of the car

Cooling of salon is made as follows:

a) Turn on the air conditioner, having pressed the A/S button, - the control lamp which is built in the switch has to light up;
b) Check that the handle of the regulator of air temperature was turned in extreme left situation;
c) Install the handle of switching of the directions of air supply in situation;
d) At high humidity of external air include the circulation mode, at low humidity, - the mode of inflow of fresh air;
e) By means of the handle of a choice of the high-speed mode of the fan establish the demanded intensity of air supply in salon.

If the car staid a long time on the sun and air in salon strongly heated up, quickly to reduce temperature in salon as follows:

a) Start the engine;
b) Turn on the air conditioner. Check that the handle of the regulator of air temperature was turned in extreme left situation;
c) By means of the handle of a choice of the high-speed mode of the fan establish the maximum intensity of air supply in salon;
d) Partially slightly open windows and turn the handle of switching of the direction of distribution of air in situation. Include the mode of inflow of fresh air.

After air temperature in salon decreases to the acceptable level, close windows and set the normal mode of air conditioning.

Operation of the air conditioning system leads to increase of load of the car engine therefore it is necessary to watch closely an arrow of the index of temperature of cooling liquid, moving with frequent stops and at a small speed in the conditions of an intense city cycle, or overcoming long raising of the considerable steepness. At approach of an arrow of the index to the red range of a scale, temporarily switch off the air conditioner until temperature of the engine does not return to norm.

Heating of salon of the car

To lift air temperature in salon of the car, execute the following manipulations:

a) Start the engine;
b) Install the handle of switching of the directions of distribution of air in situation. The mode of air circulation has to be switched off;
c) By means of the handle of a choice of the high-speed mode of the fan establish the demanded intensity of air supply in salon;
d) Turning the air temperature regulator handle in this or that party, establish desirable degree of heating of air.

Heating of salon with simultaneous drainage of air by means of the conditioner

During the work of central air humidity of air in salon of the car decreases therefore simultaneous inclusion of systems of heating and conditioning allows to make air in salon of the car warm and dry:

a) Turn on the fan;
b) Turn on the air conditioner;
c) Install the handle of switching of the directions of distribution of air in situation. The mode of air circulation has to be switched off;
d) Turning the air temperature regulator handle in this or that party, establish desirable degree of heating of the air coming to salon. In this mode cold air from the conditioner mixes up with warm air from a heater.

Joint inclusion of systems of heating and air conditioning can be applied in any traffic conditions when temperature of air is above 0 °C.

Removal from glasses of condensate and hoarfrost

It is possible to clear internal surfaces of glasses of the condensed moisture as follows:

a) Turn on the fan;
b) At the corresponding complete set of the car turn on the air conditioner;
c) Install the handle of switching of the directions of distribution of air in situation. The mode of air circulation has to be switched off. Some options of execution of the car provide possibility of automatic inclusion of the mode of supply of fresh air and its conditioner by installation of the handle of switching of the directions of distribution of air in situation;
d) Turn the air temperature regulator handle in such situation that warm air moved through nozzles of an obduv of a windshield;
e) Include an electric heater of back glass for faster removal of the condensed moisture from its surface. On some options of execution of the car if the handle of switching of the directions of distribution of air is in any situation except, the conditioner of air remains included. For switching off of the conditioner press the А/С button.

To remove from an external surface wind and lateral glasses the hoarfrost or ice formed after the parking of the car on the street in frosty weather, execute the following manipulations:

a) Include ignition, having turned a key in the lock in situation "ON" (II);
b) Install the handle of switching of the directions of distribution of air in situation. The mode of air circulation has to be switched off. Some options of execution of the car provide possibility of automatic inclusion of the mode of supply of fresh air and the conditioner, by installation of the handle of switching of the modes of the direction of distribution in situation;
c) Turn the air temperature regulator handle in extreme right situation (the maximum heating of air) and turn on the fan on the maximum speed;
d) Start the car engine.

For acceleration of cleaning of a windshield of hoarfrost or ice it is recommended to include the air circulation mode in very cold weather at first. After the windshield is exempted from frost, resume supply of fresh air for the purpose of prevention of fogging of glasses.

In the mode of an obduv of glasses all given to salon of air arrives through the slot-hole nozzles located from above on the dashboard at the windshield basis and also via lateral ventilating deflectors of the dashboard. Air temperature, the blowing glass, and the speed of purification of glasses increase in process of warming up of the engine. For acceleration of process of removal from a windshield of condensate, hoarfrost or ice it is possible to direct on it the top lateral deflectors of the dashboard.

For reasons of safety it is not necessary to begin the movement until all windows of the car are not cleared of condensate, and the adequate review will not be provided to the driver.

Switching off of systems of heating and ventilation

Temporarily to disconnect systems of heating and ventilation, turn handles of regulators of the high-speed mode of the fan and air temperature in the extreme left provisions.

Need for shutdown of systems arises the first some minutes after start of the engine in cold weather as it provides faster warming up of the engine up to the temperature sufficient for effective functioning of a heater. Keep the fan in all other cases constantly included in order to avoid an air stagnation in salon.

The models equipped with system of automatic air conditioning (climate control)

The control panel design is presented by functioning of system of climate control on an illustration.

1 — the Switch of the mode of automatic functioning (AUTO)
2 — the Switch of system of climate control
3 — the Switch of a conclusion of indications of the external thermometer
4 — Vyklyuchetl of the mode of removal of condensate from glasses
5 — the Switch of heating of back glass
6 — the Switch of a choice of the high-speed mode of functioning of the fan

8 — the Switch of a choice of the directions of distribution of an air stream
9 — the air circulation Switch
10 — temperature Regulator
11 — the Built-in thermometer of measurement of air temperature in salon

Activation of the mode of automatic control (AUTO)

The AUTO mode is activated by the sector AUTO button located in the left part of the control panel. In the AUTO mode (on the control panel the indicator inscription of the corresponding contents is highlighted) the system of climate control starts regulating automatically air temperature in salon according to the installations entered by the user. The parameters traced by system are among: temperature of the air arriving from air ducts, speed of rotation of the fan, the direction of distribution of an air stream, the mode of circulation and activation K/V.

Activation of the mode of energy saving (ECON)

Repeated pressing the AUTO button at already activated AUTO mode leads to transition of system to the mode of energy saving (ECON), - on the control panel the indicator inscription of the corresponding contents is highlighted.

 In the ECON mode on glasses condensate therefore at the increased humidity of air are recommended to use the AUTO mode is easily besieged, - press the AUTO button once again.

Transition to manual control mode

For transfer of system from the AUTO mode in manual control mode (MANUAL) it is enough to press the button "", " ", "MODE", "А/С" or, - the AUTO indicator on the control panel has to go out. Pressing the listed above buttons leads to activation of possibility of autonomous regulation of the corresponding parameter (glass heating, inclusion/switching off of the mode of circulation, a choice of the direction of distribution of air, activation To/in and a choice of the high-speed mode of the fan respectively).

 Thus automatic control of other working parameters remains.

Switching off of system of climate control

Pressing the sector OFF button leads to shutdown of the K/V compressor and fan of forcing of air in salon), at the same time there is an automatic transition to the mode of supply of fresh air (""). Remark: On models with a right-hand steering shutdown the climate of control is followed by transition to the circulation mode ("").

 Activation of system of climate control at the movement with the lit running fires can lead to decrease in brightness of illumination of devices, - for restoration of intensity of illumination press the OFF button and hold it pressed within about 1 second.

Conclusion of indications of the external thermometer

Pressing the OUT.TEMP button at the included ignition (a key in the situation ON) allows to display for the period of about 5 seconds of the display the indication of the external thermometer. After the specified term the display will return to a conclusion of value of air temperature in salon. Keeping of the button pressed within more than 2 seconds transfers the display to the alternating mode when values of temperatures of external and internal air are alternately brought to it.

 In a bright sunny weather, at the long parking with the working engine, and also at the movement in an intense city cycle (the mode start feet) the overestimated indications of temperature can be issued.

Inclusion of heating of glasses

The button "" is used in need of fast warming up or drying wind and lateral glasses. When pressing the button in salon fresh air starts moving, the compressor of the conditioner is activated (if it was switched off), and the stream of air goes on having blown in glasses, - on the control panel the indicator "" is activated.

After condensate is completely removed from a surface of glasses system it is necessary to return to the AUTO mode by pressing of the button "AUTO", "OFF" or repeated pressing the button "".

Choice of the high-speed mode of functioning of the fan

The switch allows to make a choice of one of five fixed modes: AUTO and four high-speed.

At an AUTO mode choice the speed of rotation of the fan gets out system of climate control automatically, depending on air temperature in salon, ambient temperatures, intensity of sunlight, etc.

Further pressing the OUT.TEMP button lead to gradual increase in speed of rotation of the fan then, - to return to the AUTO mode.

Compulsory activation To/in

 At a temperature of external air below 0 of °C of shutdown of the K/V compressor does not occur.

If fogging of glasses happens in the AUTO mode of system of climate control, removal of condensate can be made by pressing the A/S button. thus there is an activation of the K/V compressor, and on the control panel the indicator of the corresponding contents ("A/S") is highlighted. return to the AUTO mode can be made by means of the AUTO button.

Choice of the directions of distribution of an air stream

The choice of the directions of distribution of an air stream is made by means of the MODE switch on the control panel of system. Possibility of a choice of one of four options of distribution of air is provided:

Air supply on front level;
Air supply on front level and in foot wells;
Air supply in foot wells;
Air supply in foot wells and on having blown in a windshield.

Air circulation mode choice

The push-button switch " " on the control panel of system of climate control allows to choose one of two possible modes: the giving mode in salon of fresh air and the mode of circulation, - on the control panel is highlighted the corresponding indicator ("" or "")

The mode of circulation allows to carry out fast warming up of salon in cold weather, and also prevents hit in the car badly of the smelling air.

 Inclusion of the mode of circulation for a long time can lead to fogging of glasses, besides, in view of limitation of volume the air closed in salon quickly becomes stuffy. Do not forget to turn off the mode of the closed circulation when need for it disappears!

Choice of temperature condition

 It is always recommended to establish regardless of a season temperature of +25 °C. The chosen value remains even after ignition switching off, however shutdown of the battery leads to dumping of adjusting parameters.


The rotary handle of a choice of temperature condition is located in the left part of the control panel.

Rotation of the handle in the direction clockwise leads to increase in adjusting value of temperature which then will be automatically maintained in salon by system of climate control. For reduction of adjusting value of temperature it is necessary to turn the handle counterclockwise. Range of change of entrance data lies ranging from +18 °C to +32 °C, the step of change of temperature makes 0.5 °C.

The system of climate control continues to function in the mode of the maximum return until the preset value of air temperature in salon is reached. Told means that attempts of acceleration of process of warming up/cooling of salon by change of adjusting value of temperature do not make sense.

Information sensors

In system of climate control some information sensors are used. Sensors possess high sensitivity and careless handling of them can lead to violation of serviceability of functioning of all system. Try not to subject sensors to shock loadings, avoid hit on them of moisture, do not put on the dashboard in the locations of sensors foreign subjects.

The sensor of intensity of sunlight is built in the dashboard close with the deflector of a slot-hole nozzle of an obduv of a windshield.

The air temperature sensor in salon is located in the left bottom corner of the control panel with functioning of system of climate control.

The sensor of temperature of external air is behind a decorative front grille.
