Power Lumbar

Your vehicle has power lumbar on the driver’s and front passenger’s seats.

The seatback lumbar

The seatback lumbar support can be adjusted by moving the control located on the outboard side of the seat cushions.

To increase or decrease support, hold the control forward or rearward.

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.
