Function Setting
Normal setting
The system automatically cools or heats depending on
the outside temperature and the selected interior tem­
perature.
• In the cooling mode, air is directed only to the
adjustable air outlets (7), (8) and (9).
• In the heating mode, warm air is primarily directed to
the foot area and additionally to the ducts in the front
1480
doors.
In the heating mode, air will also be periodically
emitted from the adjustable air outlets (7).
Enough air is supplied to the windshield and to the
side windows to keep the glass free of fog in normal
weather conditions.
At low outside temperatures, fan operation does not
start until the engine coolant has warmed up.
^ EC (ECONOMY) = Economical setting
The function of this setting corresponds to the "Normal"
setting, however, because the air conditioning compres­
sor will not engage (fuel savings), it is not possible to air
condition in this setting.
