Hummer 2005 H2 - Manual (Page 15)

{ 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 seat(s) to the upright position, do the
following:
1. Lift the seatback up and push it rearward all the way.
2. Lower the seat cushion until it latches into position.
3. Pull forward on the seatback and up on the seat
cushion to make sure the seat is securely in place.
4. Return the head restraints (SUV only) to the
upright position.
