Power Lumbar

Your vehicle may have power lumbar on the

To increase or decrease support, hold the control

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