If your vehicle has this feature, the controls are located on the outboard sides of the front seats.

Use the power seat controls first 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.
