Power Seats If your vehicle has power reclining seats, you can use the vertical control to adjust the angle of the seatback. Move the reclining front seatback rearward or forward by moving the control toward the rear or the front of the vehicle. See Reclining Seatbacks on page 1-6. Power Lumbar Your vehicle's seats may be equipped with power lumbar. You can increase or decrease lumbar support in an area of the lower seatback with this control, located on the outboard sides of the front seat(s). If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats. • Raise or lower the front of the seat cushion by raising or lowering the forward edge of the horizontal control. • Move the seat forward or rearward by moving the whole horizontal control forward or rearward. • Raise or lower the rear of the seat cushion by raising or lowering the rear edge of the horizontal control. To increase support, press and hold the front of the control. To decrease support, press and hold the rear of the control. Let go of the control when the lower seatback reaches the desired level of support. You can also reshape the side wing area of the lower seatback for more lateral support. • Moving the whole horizontal control up or down raises or lowers the entire seat cushion. 1-4
