Ventilation, heater and the conditioner of air of salon


Vozduhovypusknye channels

Air giving through the channels intended for it is regulated depending on the chosen control mode - automatically or manually.

On an illustration places of giving of air, placed on the panel of devices are shown.

On any of channels can arrive нагретый, not нагретый or cooled fresh air.

Management of air distribution is carried out by the multiitem switch About (heater) or conditioner keys.

Приточные deflectors 3 and 4 can be closed or open the corrugated handles separately located on each side.
The direction of giving of air through приточные deflectors can be regulated both in vertical, and in horizontal planes.
The conditioner automatically supports a uniform microclimate in all space of salon.

For this purpose the temperature arriving on приточным to air channels, and also its mass expense (quantity) and distribution of air streams automatically changes. In need of given automatic process it is possible to introduce manual corrective amendments.

On the display of the control panel the conditioner established on the average console, deduces indication of the programmed temperature and fan turns. On the left side of the display there is a key of regulation of temperature, and with right - a key of regulation of turns of the fan. Regulation of temperature and fan turns is carried out by pressing of keys “+” or “-”.

Open приточные deflectors 3 and 4.

If necessary establish воздухораспределитель With in other position.

General provisions

For normal work of system of heating and ventilation the air inlet located before a windscreen should not be hammered by snow, ice and foliage.

The fan should be constantly included in avoidance запотевания glasses on small speed on low power.

For the termination of hit of polluted external air in salon press key D. In avoidance запотевания glasses movement in this mode should not be long-term.

The antidust filter catches the weighed microparticles of external air (for example, a dust, pollen etc.). Establish the switch in position 0 only in case of pollution наружно air gases.

Element of the antidust filter replace according to the plan THAT for the purpose of prevention of falling of capacity of a heater.

Controls air conditioner

All modes of the conditioner will join and will be switched off by pressing of keys. At the included mode in соответсвующей to a key the diode burns.

Typical adjustment

After ignition inclusion:

Establish temperature 22С (71F) and press key AUTO.
Such adjustment provides as much as possible fast creation in salon of a comfortable microclimate.

Therefore to recede from it there is a sense only in the event that it is dictated by own state of health.

AUTO automatics (a regular mode)

The temperature, quantity and air distribution are regulated automatically, by criterion of the quickest achievement and the subsequent maintenance of the necessary temperature in salon. Automatic reaction to fluctuations of temperature of external air, and also to sun influence is thus provided.

TEMP temperature regulation

The temperature in salon can be set in limits from 18С (64F) to 29С (84F). At regulator installation in one of extreme positions “LO” and “HI”, temperature regulations do not occur. The system constantly works in a mode maximum hlado - or теплопроизводительности.

Temperature indication can be switched from Celsius scale to the Fahrenheit scale and back in a following order:

Press and keep a key

Then press плюсовую a key of regulation of temperature.

Heating (defrosting of glasses)

As much as possible fast defrosting/clearing from запотевания wind and lateral glasses.

The temperature is regulated automatically. The maximum giving of air is carried out mainly on channels 1 and 2.

Pressing of the given key switches off a mode of circulation and an economic mode.

Circulation mode

In a mode of circulation air access from the outside прекрывается, and its volume is distributed in salon on a circle. Thereby hit in salon of the car of air polluted by exhaust gases is prevented. Movement in the given mode should not be too long-term.

At запотевании glasses at once include a mode

In need of short-term switching-off of the compressor of the conditioner, for example, owing to excessive loading of the engine, again press an air circulation key.

ECON an economic mode

For economy of fuel it is possible to switch off the compressor. However at the disconnected compressor possibilities поддерживания a comfortable microclimate in salon are limited. If in salon becomes too hot or glasses it is possible to include again the compressor pressing of key ECON or AUTO will mist over.

OFF conditioner deenergizing

By pressing of the given key the conditioner is switched off. Access of external air is blocked.

For conditioner inclusion press key AUTO or one of keys of the fan/regulation of temperature, воздухораспределителя, or клавшу OFF.

Correction of turns of the fan

Pressing of keys “+” or “-” the turns of the fan set by automatics change. Actual turns are displayed in the form of segment indication of the display.

Heating сиденья*

Heating of back glass

Keys воздухораспределения


It is possible to change the programmed mode воздухораспределителя. Probably both separate, and the combined manipulation these keys.

If necessary to return to an automatic mode, disconnect corresponding functions by pressing of the given keys separately or pressing of key AUTO.

Air giving to glasses

All expense of air is realised on channels 1 and 2. Unlike a mode the quantity of air does not increase.

Air giving from outside panels of devices

All expense of air is realised with giving through deflectors 3 and 4 panels of devices.

Air giving in space for feet

All expense of air is realised through приточные channels 5 and exits of air channels under forward seats.

Key recognition

The basic manual parametres of adjustment of the conditioner are programmed for convenience of using automatically.

At change of parametres of adjustment of the conditioner by other user of your car, after ignition inclusion automatically there is their installation in a starting position according to the parametres programmed on your key.

Necessary condition for this purpose is use by the previous user not yours, and other key of the car. Otherwise there will be a programming of the parametres established by the given user on your key.

Therefore at using the car several drivers everyone should use the key for automatic installation of the set parametres of the conditioner.

General provisions

The fan joins in cold weather only after warming up of a cooling liquid to the necessary temperature. The exception makes a mode.

In order to avoid falling warmly - and хладопроизводительности, and also запотевания glasses important that the air inlet before a windscreen was not hammered by snow, ice or foliage.

On cars with automatic transmission, at sharp трогании with completely squeezed out pedal of an accelerator, or at anticipatory switching on a hill-climbing gear (Kick-Down) the conditioner compressor is disconnected for some time for realisation of a total power of the engine.

The compressor is disconnected at too heat of a cooling liquid for maintenance of normal cooling of the engine in the conditions of extreme loading.

In cold weather the compressor is automatically switched off. In this case it will not manage to be included and key AUTO intended for it.

At the included compressor the temperature and humidity of air in salon go down. Thanks to it it is prevented запотевание glasses.

The conditioner works most effectively at closed podemno-sdvizhnoj panels крыши* and the lifted glasses.
If, however, air in salon has heated up as a result of long parking of the car on the sun lowering of glasses for short time before conditioner inclusion can accelerate cooling process.

At high external temperature and humidity from the evaporator the condensed water, forming a pool under the car can drip. This normal phenomenon which is not a sign of depressurization.

The antidust filter catches the weighed microparticles of external air (for example, a dust, pollen etc.). Include a circulation mode at impurity of air exhaust gases.

Element of the antidust filter replace according to the plan THAT for prevention of loss of capacity of the conditioner.

At premature pollution of the filter as a result of car operation in zones with strong air pollution more frequent can be demanded, than THAT is provided by the plan, replacement of a filtering element.

Arriving through приточные channels and distributed then on all salon air leaves through exhaust cracks under back glass. Therefore do not close their subjects of clothes, etc. things.

At the slightest suspicion on conditioner damage at once switch off it and check up on HUNDRED Audi.
Only after that it is possible to maintain the conditioner again.

For repair of conditioners Audi highly skilled masters and the special tool are necessary.
Therefore at malfunctions of the conditioner address on HUNDRED Audi.
