Power Lumbar The driver's and passenger's seatback lumbar support switches are located on the outboard sides of the seats. Heated Seats Your vehicle may have heated front seats. The buttons are located on the climate control panel. Use the power seat controls first to get the proper position, then continue with the lumbar adjustment. Use the top lumbar switch to adjust support to the middle seatback and the bottom lumbar switch to adjust support to the lower seatback. Press the front of the switch to increase support and the rear of the switch to decrease support. 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. z(Heated Seat and Seatback): This button is for the heated seat and seatback. Press the up arrow once to turn on the heated seat at the highest setting.
