Using the system in recirculated air mode

The windows will fog up more easily if recirculated air mode is used for 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.

When the outside temperature exceeds 75 F (24 C) and the air conditioning system is on

In order to reduce the air conditioning power consumption, the air conditioning system may switch to recirculated air mode automatically. This may also reduce fuel consumption.
