This mode is used to direct heated air to the foot outlets. Some air also flows from the defrost outlets and the side vent outlets.
Ventilation
This mode directs outside air to the side and center vents.
Defrosting or defogging
This mode directs the air to the defrost outlets to defrost/defog the windows.
Bi-level heating
The bi-level mode directs warmed air to the side and center vents and to the front and rear floor outlets.
Heating and defogging
This mode heats the interior and defogs the windshield.
The indicator light on the A/C button will
remain in Off. This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing outside
air to be drawn into the passenger
compartment to further improve the defogging
performance.
Operating tips
Clear snow and ice from the wiper blades and air inlet in front of the windshield. This improves heater operation.
