PERFORMANCE ORDER

Establish temperature of 22 °C (71 °F), Press the <AUTO> key.

Such control provides the fastest creation in salon of a comfortable microclimate. Therefore to recede from it there is a sense only if it is dictated by own health.

The conditioner represents a combination of a heater, the fan and refrigerator working in the automatic mode. The conditioner provides decrease of humidity and cooling of air in salon.

The conditioner completely automatically supports the set temperature condition in salon of the car. For this purpose automatically temperature and amount of the air arriving on stitched channels change, and also air streams are distributed. The conditioner reacts also to sunlight and therefore manual adjustment is not required. For this reason the automatic mode almost in all cases represents optimum option of good health in the car at all seasons of the year.

In the cooling mode humidity of air in salon goes down. Thanks to it fogging of glasses is prevented.

At the high external temperature and humidity from the evaporator the condensed water can drip, forming under the car a pool. It normally and is not a depressurization sign!

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

At sharp start-off with completely squeezed out accelerator pedal the compressor of the conditioner is switched-off for some time for realization of full capacity of the engine.

The compressor is switched-off at too high temperature of cooling liquid for ensuring normal cooling of the engine in the conditions of extreme loading.

Filter of thin cleaning

The filter (consisting of the filter of microparticles and absorbent carbon) substantially reduces amount of the dust containing in external air, pollen, gases, etc.

Change an element of the filter according to the Schedule of maintenance.

If you had suspicions that the conditioner is faulty, it is necessary to include at once the ECON mode and to check the conditioner.

In order to avoid falling warm and refrigerating capacities, and also foggings of glasses important that the air inlet before a windshield was not hammered with snow, ice or foliage.

Arriving via stitched channels and distributed then on all salon air is removed through exhaust cracks under back glass. Therefore do not close them articles of clothing, etc. things.

The conditioner works most effectively at the movable panel of a roof closed podjyomno * and the lifted glasses. If, however, air in salon heated up as a result of the long parking of the car on the sun, lowering of glasses for a short time before turning on of the conditioner can accelerate cooling process.
