The upper shoulder height markers indicate the maximum shoulder height for a child in the restraint. When the child’s shoulder is at the top marker they are ready to move to the next type of restraint.
The lower shoulder height marker indicates the minimum shoulder height for a child before they can be turned around to a forward facing position. If the child’s shoulder is below the marker they should remain rear facing.
For an A2 convertible child restraint this marker is a minimum of 35 cm
A4 Height Markers

Th A4 child restraint was introduced in 2013 Australian Standard, which was finally approved on 17 September 2014.

The convertible seat height markers provide guidance that ensures your child’s safety.
The highest Rear Facing Shoulder height markers should be at 39 cm. However there are some car seat manufacturers which do not have the second should height marker for rear facing at 39 cm, these being the Maxi Cosi Euro and Maxi Cosi Hera which have the second marker at only 37 cm.
