[ (Floor): This mode directs most of the air to the floor outlets with some air directed to the outboard outlets (for the side windows), and a little air directed to the windshield. The mode switch can also be used to select the defog mode. Information on defogging and defrosting can be found later in this section. Recirculation is not available in the defrost mode and will automatically turn off after 10 minutes when defog is selected.
