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. There are diagrams of the various methods of installation for this mode on the labels, but they are labeled with icons and it is not clear that these are installation modes to select from. There is no indication of how to fit the harness to the child for this mode of use 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 text only (not illustrated) in the manual. No complete illustration of a child in the CRS is shown next to height/weight information. There is not an overview of the acceptable methods of installation for this mode. The warning that the rear seat is the safest place in a vehicle for children is located amongst other warnings. The belt routing section does not give routing instructions for lap-only seat belts.
Securing the Child 3 stars
After using the car seat in booster mode for an older child, to convert the seat back to this mode of use, the harness must be reinstalled. The harness must be rethreaded to adjust for the child's growth as well as for reassembly after cleaning. Loose parts may be generated when disassembling for cleaning. When converting to forward-facing mode, the LATCH belt must be rerouted through the belt path.
Installation Features 5 stars
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.
