Chevrolet 2004 Tahoe Owner's Manual page 64

Tahoe/Suburban models with rear seats: A child
restraint with a top strap should only be used in
the second or third row. Don't use a child restraint with
a top strap in the front seat because there's no place
to anchor the top strap.
An anchor loop bracket for a top strap is located at
the bottom rear of the seat cushion for each seating
position in the second row, and for the center seating
position in the third row.
