4-Way Power Lumbar Control (Option) If you have this option, the driver's and passenger's seatback lumbar support can be adjusted four ways by moving the single switch located on the outboard side of the seat. Memory Seat and Mirrors (If Equipped) If your vehicle has this feature, the controls on the driver's door panel are used to program and recall previous settings. To increase or decrease support, hold the switch forward or rearward. To move the lumbar up or down, hold the switch upward or downward. You can use this function to save your seat cushion positions (including the shoulder belt height adjuster), recliner, lumbar, mirror adjustment, personal choice settings, comfort controls and radio settings. 1-3
