@ EC (ECONOMY) = Economical setting; the air
conditioning com pressor stays off.
In any other settings, the air conditioning com pressor
com es on with ambient tem peratures above + 2 ° C/
+ 36° F.
We recom mend this setting to be used with cool outside
tem peratures so that the air conditioning com pressor
stays off in order to save fuel.
In the ventilation mode, air is emitted from nozzles (1)
and (2).
In the heating mode, warm air is primarily supplied to the
fo o t area. Only an am ount of air sufficient to prevent fog
build-up under normal clim atic conditions will be
channeled to the windshield and the movable (2). At
times, air will be em itted from the movable (1).
W ith cold outside tem peratures, the fresh air supply and
the fan remain turned off until the engine coolant has
wamred up slightly.
^ Normal setting
We recom m end this setting with humid and warm
outside tem peratures.
The setting ^ corresponds with setting @ but, in
addition, the air can be cooled or heated as necessary.
