0 EC (ECONOMY) = Economical setting; the air
conditioning compressor remains off.
In the remaining three settings, the air conditioning com­
pressor comes on with ambient temperatures above
+ 5° C (41° F).
As a fuel saving measure, we recommend this setting be
used with cool outside temperatures, so that the air con­
ditioning compressor remains off.
In the ventilation mode, air is emitted from outlets (7), (8)
and (9).
In the heating mode, warm air is supplied primarily to the
foot area. In addition, warm air is also supplied to the
ducts in the front doors. Only enough warm air is sup­
plied to the windshield and air outlets (8) and (9), to keep
the glass defogged in normal weather conditions. In the
heating mode, air may be emitted periodically from out­
lets (7), depending on the interior temperature.
With low outside temperatures, fan operation is can­
celled until the engine coolant starts to warm up.
0 Normal setting
This setting is recommended when you wish to cool the
interior of your car. It is also recommended for use in
humid weather.
The setting 0 corresponds with setting 0 but, in
addition, the air can be also cooled as necessary.
