Rear Blower Control
The primary control for the rear blower is on the front
climate control unit, located on the instrument panel.
Only when the front control for the rear blower is in the
REARposition do the second row seat occupants have
control of the rear blower speed.
The rear blower control, located in the rear overhead
console, has an off position and a range of blower speeds.
This allows the second row seat occupants to control the
volume of air circulated in the rear of the vehicle.CAUTION!
Interior air enters the Rear Manual Climate Control
system through an intake grille, located in the right
side trim panel behind the third row seats. The
heater outlets are located in the right side trim panel,
just behind the sliding door. Do not block or place
objects directly in front of the inlet grille or heater
outlets. The electrical system could overload, causing
damage to the blower motor.
Rear Temperature Control
The rear mode selection REAR,allows the settings to be
controlled by the rear mode control knob.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob counterclockwise for
cold air, and clockwise for heated air.

the temperature doors will continue to operate automati-
cally. There are seven fixed blower speeds.
Use the outer dial control to regulate
the amount of air forced through the
system in any mode you select. The
blower speed increases as you move
the control clockwise and decreases
when you move the control counter-
clockwise.
The blower fan speed can be set to any fixed speed by
adjusting the blower control outer dial. The fan will now
operate at a fixed speed until additional speeds are
selected. This allows the front occupants to control the
volume of air circulated in the vehicle and cancel the
Auto mode.
