Function Setting
P I Normal setting
The system automatically cools or heats depending
on the outside temperature and the selected inte­
rior temperature.
• In the cooling mode, air is directed only to the
adjustable air outlets (6) and (8).
• In the heating mode, warm air is primarily di­
rected to the foot area.
In the heating mode, air will be emitted inter­
mittently from the adjustable air outlets (6).
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.
P i EC (ECONOMY) = Economical setting
The function of this setting corresponds to the
'' Normal" setting, however, because the air con­
ditioning compressor will not engage (fuel savings),
it is not possible to air condition in this setting.
