Raise or lower the rear part of the seat cushion by
moving the rear of the control up or down.

control up or down.
On seats with power reclining seatbacks, the control is
located behind the power seat control on the outboard

Keep in mind that as your seating position changes,

your vehicle and the remote recall memory feature
is on, automatic seat, adjustable mirror, and adjustable

If something has blocked the driver’s seat and/or the
adjustable pedals while recalling a memory position,

and press the appropriate control for the area that
is not responding for two seconds. Try recalling
the memory position again by pressing the appropriate
memory button. If the memory position is still not
