BOOSTER (For children approx. 4 years to 6 - 8 years of age)
MINIMUM HEIGHT
Your child can use the Hi-Liner SG once their shoulder's are in line with the Lower Shoulder Height Marker with the headrest in the lowest position. If below the Lower Shoulder Height Marker your child is too small for the Hi-Liner SG and should remain in a restraint with an in-built harness.
MAXIMUM HEIGHT
Your child can continue to use the Hi-Liner SG until their shoulder's reach the Upper Shoulder Height Marker with the headrest fully raised. When they reach this stage they then need to move to the next form of restraint.
