■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions, etc. As a result, the following may occur.
●Immediately after is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
●Cool air may flow to the area around the upper body when the heater is
on.
■Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with under these condition, such as temperature setting and
inside temperature.
Also, outside air mode may be automatically switched to when the outside
temperature is low.
■When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on
●In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
●Recirculated air mode is selected as a default mode when the “POWER”
switch is turned to ON mode.
●It is possible to switch to outside air mode at any time by pressing
