To adjust the power seats: Horizontal Control: Raise or lower the front of the seat by pressing the forward edge of the control up or down. Raise or lower the rear of the seat by holding the rear edge of the control up or down. Move the seat higher or lower by holding the whole control up or down. Vertical Control (Option): Move the seatback into a recline position by pressing the top of the control back. Move the seatback forward by pressing the top of the control forward. Power Lumbar Control (Option) The lumbar control is located on the outboard side of each front seat. Use the power seat control first to get the proper position. Then proceed with the lumbar adjustment. To reshape the lower seatback, 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. 1-3
