Air Select Knob

The air select knob allows you to direct heated air into the passenger compartment through different outlets.
1. Vent - In this position, air is discharged from the upper air outlet. Air quantity is controlled by the fan control knob.
2. Bi-Level - In this position, air flow is divided between the upper air outlets and the floor air outlets, with warmer air delivered to the floor outlets than the air delivered to the upper air outlets.
3. Foot - In this position, air flow is delivered to the foot while sending approx 30% of total amount air to the wind shield.
4. Def/Foot - In this position, air flow is delivered to the foot, while sending approx. 40% of total amount of air to the windshield. Selecting this mode allows air conditioning system to work when the fan switch is turned to ON position, even if the A/C switch is off.
5. Defrost - In this position, most of the air is delivered to the windshield and a small amount is delivered to the side windows.

Moving the air source select lever to the "CIRC" position provides quickest heat delivery by closing the blower assembly mode door. In this position, outside air is not delivered to the passenger compartment.
Selecting this mode allows air conditioning system to work when the fan switch is turned to ON position, even if the A/C switch is OFF.
