Power Lumbar
If the seats have power lumbar, the controls used to
operate this feature are located on the outboard
side of the seats.
•
To increase lumbar support, press and hold the
front of the control.
•
To decrease lumbar support, press and hold
the rear of the control.
•
To raise the height of the lumbar support, press
and hold the top of the control.
•
To lower the height of the lumbar support,
press and hold the bottom of the control.
Release the control when the lower seatback
reaches the desired level of lumbar support.
Your vehicle may have a memory function which
allows seat settings to be saved and recalled.
See Memory Seat, Mirrors, and Pedals on page 13
for more information.
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.
