Power Lumbar The vehicle may have additional features to adjust your vehicle's power seat: • 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 1-8 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. On seats with 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. 1-7
