to keep the rear seat secure.
8. Store the rear safety belts and buckles in the

CAUTION:

If the seatback isn't locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it is
locked.
CAUTION:
{
A safety belt that is improperly routed, not
properly attached, or twisted won't 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.
