equipped with a rear seat climate control system, the instrument
panel will also include a rear seat climate control knob. To turn
on the rear passenger compartment control system, select REAR
CTRL, Medium Low, Medium High, or High. With the knob set
to REAR CTRL, rear seat passengers will have control of rear
fan speed on the rear seat climate control panel. Positions

The climate controls — main and auxiliary system A/C — Heater System — if
equipped
The standard heating system and the heating portion of the
heating and air conditioning system are essentially identical.
There is one exception, however; the air conditioning
compressor will automatically engage when the P
(DEFROST/FLOOR) or V (DEFROST) position is selected to
aid in defogging and defrosting the inside glass when the
outside temperature is above approximately 45˚F (7˚C). Refer to
the heating system operating instructions covered previously for
a more detailed explanation of heating system operation.
