To improve air conditioning performance, perform the following operations:

Adjust the fan speed

Turn off Eco drive mode

an extended period.

Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with the temperature setting and the inside temperature.

Window defogger feature
