CHEVROLET CORVETTE 2005 - Manual (Page 9)

Power Lumbar and Side Bolsters
Your vehicle may have power lumbar and side bolsters.
The switches are located on the outboard side of the
seat cushion.
Use the power seat control to move the seat to the
proper position. See Six-Way Power Seats on page 1-2.
Use the vertical lumbar switch (A) to adjust support in
the seatback. Press the switch forward to increase
support. Press the switch rearward to decrease support.
Use the horizontal switch (B) to adjust the side
bolsters. Pull up the switch to move the wings of the
seatback in closer to your body. Push down the switch
to move the wings away from your body.
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.
