Heating
On cold days, use FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.

Heater" in the Index.
