System Operation: Floor-Defrost

When FLOOR/DEFROST is selected:

• the RECIRC request button is enabled. If the RECIRC request button is selected (indicator on), the air inlet door closes, preventing outside air from entering the passenger compartment. If the RECIRC request button is not selected (indicator off), the air inlet door opens, allowing only outside air into the passenger compartment.
• the mode doors direct airflow to the floor duct, the defroster duct and the side window demisters.
• blended air temperature is available.
• the A/C  request button toggles the indicator on and off. To reduce fogging, the A/C  compressor operates automatically, regardless of indicator status, if the outside temperature is above approximately 6 C (42.8 F).
• the blower motor is on.
