to adjust the front portion of the cushion.
·Move the rear of the seat control up or down
to adjust the rear portion of the cushion.
·Lift up or push down on the center of the seat
control to move the entire seat up or down.

If your vehicle has this
feature, the control is
located on the outboard
sides of the front seats.
Use the power seat controls ®rst to get the proper
position, then continue with the lumbar adjustment.
Press the lumbar control forward to increase support
and rearward to decrease support. Press the control up
or down to raise or lower the support mechanism.
Keep in mind that as your seating position changes,
as it may during long trips, so should the position of your
lumbar support. Adjust the seat as needed.
1-2

Massaging Lumbar
If your vehicle has this
feature, the control is
located on the outboard
sides of the front seats.
With the ignition on, brie¯y
press the top of the control
where it is marked AUTO to
activate the massaging
lumbar feature.
The massage cycle will run continuously for up to
10 minutes and can be interrupted by brie¯y pressing the
bottom of the control. The lumbar support can be
adjusted during the massage cycle by moving the control
forward to increase support and rearward to decrease
support. The massage cycle will continue to run even if
the ignition is turned to OFF unless interrupted.
If your vehicle has this feature, it will not have the
adaptive seat feature.
Adaptive Seat Control
If your vehicle has this
feature, the control is
located on the outboard
side of each front seat.
It is marked AUTO.
With the ignition in ON, ®rst 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 in¯ate
the cushion and take a reading, then automatically
de¯ate the cushion to a suggested level of comfort by
distributing the pressure evenly. The seatback and
cushion will in¯ate to adjust to the driver's body position
in two to four-minute cycles.
1-3

You may still wish to further adjust the overall ®rmness
or softness of the seat cushion. To get to your
desired level of comfort, hold the control up to increase
the ®rmness, or down for less ®rmness. When you
let go of the control, the seat will automatically readjust
to your desired level of comfort.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support. The lumbar will then automatically
adjust to your body's positioning for the duration of the
trip in two to four-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 de¯ate. You will then
need to readjust the lumbar support upon returning to
your vehicle.
To turn off the adaptive seat feature, brie¯y press the
bottom of the control. The seat will de¯ate when
the adaptive seat control or the ignition is turned off.
If your vehicle has this feature, massaging lumbar is not
available for your vehicle.Heated Seats
Your vehicle may have heated front and rear seats.
The buttons are located on the armrests. Press the
buttons to turn the feature on. Press them again to turn
off the heated seats. The feature will also shut off
when the ignition is turned to OFF.
The HEAT/OFF button controls the temperature settings
HI, MED and LO. The other button is to choose BACK
ONLY heating. The LO setting warms the seatback and
cushion until the seat approximates body temperature.
The MED and HI settings heat the seatback and
seat cushion to a slightly higher temperature, and the
BACK ONLY heats only the seatback.
