Using the Lower Universal Anchorage System (LUAS)
The Lower Universal Anchorage System or LUAS, is a system
available on this child seat that offers an alternative to vehicle
seat belt installation methods. See pages 14 and 15 for LUAS
components on this child seat.
The figure above shows typical locations for lower anchors and
tether anchors in a vehicle. Check your vehicle owner's manual to
learn if it is equipped with the LUAS, the maximum weight rating for
the lower anchors, and for information on the lower anchor locations
and seating positions available for use with this child seat.
Standard vehicle seat spacing between LUAS anchors is 27.9 cm
(11 inches). This child seat can be used in a seating position with up
to 50.8 cm (20 inches) of space between LUAS anchors if the vehicle
manufacturer allows.
