Evaluation of Labels 1 stars
There is not a full picture of a child properly restrained in the child seat directly next to sizing information on the labeling. Supplemental sizing information is missing from the labels. The tether is not labeled in the illustrations depicting acceptable modes of installation. No indication of correct harness height relative to the child is given on the labels. The labels do not explain how to use LATCH or the top tether in detail.
Evaluation of Instructions 3 stars
The instruction manual storage location cannot be accessed while the child is seated in the seat. Supplemental sizing information is given in short, simple text. No complete illustration of a child in the CRS is shown next to height/weight information. There is no overview of installation methods for this mode of use. The warning that the rear seat is the safest place in a vehicle for children is located amongst other warnings and is not illustrated. No step-by-step instructions are given specifically for installation with lap-only seat belts.
Securing the Child 3 stars
There are fewer than three harness slots to use in this mode of use. The harness must be rethreaded to adjust for the child's growth. When converting to forward-facing mode from other modes of use, the LATCH belt must be rerouted. Loose parts may be generated when disassembling for cleaning.
Installation Features 3 stars
It may be uncomfortable for those with larger hands to route the seatbelt or LATCH belt through the belt path. The LATCH attachments have buttons to depress for removal from the vehicle's LATCH anchors. The storage system for the LATCH attachments is labeled with a latchplate icon which users may find confusing.
