■ Operation of the air conditioning system in Eco drive mode

To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
The air conditioning control of Eco drive mode can be changed to the same setting
as that used in normal drive mode. (Customizable featuresP. 874)
■ Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur:
● Immediately after the “AUTO” button 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.
