Rear Automatic Temperature Control (ATC) — If
Equipped
The Rear ATC System has floor air outlets at the rear of
the right side sliding door, and overhead outlets at each

heated air through the floor outlets or cool, dehumidified
air through the headliner outlets.

on the front lower ATC panel located on the instrument
panel.
Pressing the REAR LOCK button for the Rear ATC
System from the front lower ATC panel, illuminates a
LOCK symbol in the rear display. The rear temperature
and air source are controlled from the front lower ATC
panel.
Rear second row occupants can only adjust the rear ATC
control when the REAR LOCK button is turned off.
