Reclining Seatbacks - Chevrolet 2002 Corvette Owner's Manual

Sport Seat (Option)
If your vehicle is equipped with a sport seat, there are
three other controls that help you change the shape of the
seat in addition to the power seat control. There are two
lumbar supports for the middle (A) and lower (B) back.
There's also a side bolster control (C) that adjusts the sides
of the seat around you to give you more lateral support.
For lumbar support, move each control (A and B)
forward to inflate or rearward to deflate.
Move the side bolster control (C) up for more side
support and down for less support.

Reclining Seatbacks

The lever for the reclining seatback is located on the
outboard side of each seat, near the base.
To adjust the seatback, lean slightly forward to lift your
weight off the seatback. Pull completely up on the lever
until it stops, and lean back to position the seatback to
where you want it. Release the lever to lock the seatback
into place.
