For 1990-2009 cars

If the seats have power lumbar, the controls used to operate this feature are located on the outboard side of the seats. See "Power Lumbar" under Power Seats for more information.

To increase or decrease lumbar support, press and hold the front or rear of the control (C).

Release the control when the seatback reaches the desired level of lumbar support.

The lumbar support may need to be adjusted when changing the seating position.
