fg EC (ECONOMY) = Economical setting; the air
conditioning compressor stays off.
In any other settings, the air conditioning compressor
comes on with ambient temperatures above + 2 ° C/
+ 36° F.
We recommend this setting to be used with cool outside
temperatures so that the air conditioning compressor
stays off in order to save fuel.
In the ventilation mode, only air will be channeled to the
movable nozzles (1) and (2).
In the heating mode, warm air will mainly be channeled to
the leg room. Only an amount of air sufficient to prevent
fog build-up under normal climatic conditions will be
channeled to the windshield and the movable nozzles 2.
At times, air will be emitted from the movable nozzles 1.
With cold outside temperatures, the fresh air supply and
the blower remain turned off until the engine coolant has
warmed up slightly.
fg Normal Setting
We recommend this setting with humid and warm
outside temperatures.
