Install the Child Harness to the booster seat and anchorages as detailed previously (page 45- 46). Install
the booster seat into the vehicle. Ensure the top tether strap is attached to the vehicle upper anchorage
and adjusted correctly. With the vehicle seatbelt converted (if necessary) ready for use, thread the lap
seatbelt through the Child Harness strap loops as shown.
NOTE: Seatbelt extenders should not be used if the
seatbelt is not long enough to fit around the child. If
a seatbelt extender is used then the seatbelt buckle
must not be in contact with the child.
Use the child harness as detailed on page 55-57.
