Adaptive Seat Control (Option)
The adaptive seat control is located on the outboard side
of each front seat. With the ignition in ON, first use the
power seat control to get the proper position.
Then press the top of the control where it is marked
AUTO. The system will inflate the cushion and take a
reading, then automatically deflate the cushion to a
suggested level of comfort, by distributing the
pressure evenly.
You may still wish to further adjust the overall firmness
or softness of the seat cushion. To get to your desired
level of comfort, hold the control up to increase the
firmness, or down for less firmness. When you let go of
the control, the seat will then automatically readjust to
your desired level of comfort.

You will also need to adjust the lumbar support. To
increase the lumbar support, push forward on the control
and to decrease support, push rearward on the control.
(The lumbar will then automatically adjust to your
body's positioning for the duration of the trip in
-
two minute cycles.)
If you exit the vehicle after the system has been
activated and the seat is left unoccupied for more than
two minutes, the system will deflate. You will then need
to readjust the lumbar support upon returning to
your vehicle.
To turn off the adaptive seat feature while still in your
vehicle, press the control down briefly. The seat will
also deflate when the ignition is turned to OFF.
