the rear seats to control the flow of air
to the rear area of the vehicle. When the
heater
is on, warmed air is directed to
the third row seats and to the rear side
windows to defog them. When the air
conditioner is on, cooled air
is directed
to the second and third row seats
through upper vents. (See the
Index
under Climate Control System. )
