Top Strap - GMC C series 2002 Owner's Manual

Top Strap

Some child restraints have a top strap, or "top tether."
It can help restrain the child restraint during a collision.
For it to work, a top strap must be properly anchored to
-
the vehicle. Some top strap equipped child restraints are
designed for use with or without the top strap being
anchored. Others require the top strap always to be
anchored. Be sure to read and follow the instructions
for your child restraint. If yours requires that the top
strap be anchored, don't use the restraint unless it is
anchored properly.
Don't use a child restraint that requires a top strap in
your vehicle because the top strap anchor cannot be
installed properly.
