Pontiac 2006 G6 Owner's Manual page 17

Notice: Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
2. Fold the seatback down from inside the vehicle.
CAUTION:
{
If either seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
push and pull on the seatbacks to be sure they
are locked.
CAUTION:
{
A safety belt that is improperly routed, not properly
attached, or twisted will not provide the protection
needed in a crash. The person wearing the belt
could be seriously injured. After raising the rear
seatback, always check to be sure that the safety
belts are properly routed and attached, and are
not twisted.
To return the seatback to the upright position, push up
the seatback. Then pull on the seatback to make
sure it is secure.
