• DO NOT USE WITH JUST A LAP BELT. You must use with lap-sash seat belt, or with a
seat belt and child harness.
• The lap part of the seatbelt must be firmly across the thighs and the sash belt fitted
diagonally across the chest and on the shoulder.
• If used with a child harness, the lap belt must be adjusted firmly first, and then the harness,
so that the lap belt is not lifted off the child’s lap when the harness is adjusted.
• Use the restraint exactly as shown in the instructions.
• Supervision of children is needed because they may be able to undo the buckles and/or
special features.
• DO NOT LEAVE CHILDREN UNATTENDED IN THE CAR
• Do not alter or modify this restraint.
• Repairs must only be done by the manufacturers or agent.
• Do not allow the restraint to come into contact with polishes, oils, bleach and other
chemicals.
• Destroy the restraint if it has been in a severe crash, even if no damage is visible.
• DO NOT USE THIS RESTRAINT WITHOUT THE COVER.
• IF AN AIRBAG IS FITTED IN THE SEATING POSITION WHERE THE CHILD RESTRAINT
IS TO BE FITTED, FOLLOW THE VEHICLE MANUFACTURER’S WARNINGS AND
INSTRUCTIONS.
• The child in the seat must not slump or slouch such that the lap belt is on the abdomen.
The lap belt on the abdomen is dangerous. The lap belt positioning SecureGuard™ Anti
Submarining Device must always be used.
• Always secure the loose end of the top tether strap. Do not use the child restraint where this
strap may fall into a split in the seat back or off the side of the seat.
• ALWAYS ATTACH HOOK AND REMOVE SLACK.
• VERSATETHER - ONLY USE FOR ATTACHMENT OF CHILD HARNESS.
• DO NOT ATTACH THIS CHILD RESTRAINT TO ANY ISOFIX LOW ANCHORAGE. ISOFIX
low anchorage is cars are designed to withstand only those loads imposed by children aged

child restraint.
• This child restraint is not approved for use with any connectors that connect to the car's
ISOFIX low anchorages.

Instructions for Installation & Use 11
IMPORTANT :
• Protect all webbing from abrasion and cutting by sharp corners and edges.
• This restraint must be used facing forward and in conjunction with a lap-sash seat belt or
converted seatbelt and approved child harness.
• THIS RESTRAINT IS NOT SUITABLE FOR USE WHERE THE TOP TETHER STRAP MAY
FALL INTO A SPLIT IN THE SEAT BACK OR OFF THE SIDE OF THE SEAT.
• Seatbelt extenders are not recommended to be used if the seatbelt is not long enough to
secure the child restraint. If seatbelts are too short then seek advice from a child restraint
fitter and consider their recommendations before using a seatbelt extender. If you use a
seatbelt extender then ensure that the seatbelt buckle does not contact the child.
• This child restraint is not approved for use with any connectors that connect to the car’s
ISOFIX low anchorages
• Do not use in a front seat, unless your child is over 4 years of age or in accordance with the
applicable Road Rules in your region. Research shows that children under 12 years old are
at a greater risk of serious injury when travelling in the front seat.
• Do not use on any vehicle seat which faces sideways or rearwards.
• Use of aftermarket accessories (i.e. items not provided in the box with the child restraint),
can reduce the safety provided by the child restraint and may cause injury or death.
• Use a towel or seat protector (messy mat) to protect the vehicle seat. Protection of both
underneath and behind the booster seat may be required.
• Do not store in hot places or underneath heavy objects. The plastic may distort.
• The restraint should not be purchased or sold as a second hand item. It is recommended
not to use child restraints older than 10 years as the protection in an accident may be
reduced.
• Regularly check the restraint components, straps and other fitments for correct function,
cracking & condition. Seek immediate repair.
• Do not lift the seat by the headrest or the Side Wings.

HOW TO SETUP
ADJUSTING BASE EXTENSION
ADJUSTING THE SIDE WINGS
This booster seat has a base extension which can
be easily adjusted by rotating the knob. This is to
accommodate the leg length of larger children.
When should the base be extended?
Extend the base so that the front edge of the base
is close to the back of your child’s knees. The
upper thigh section of their legs will be supported
and the seating position is made more comfortable
by reducing pressure points.
The Adjustable Side Wings can be adjusted to
provide more width for a larger child or can be
kept narrow to reduce the width of the Booster
seat.
To adjust, hold seat or headrest with one hand
and use the other hand to lift up side wing and
rotate, let it click down into place, then do the
same for the other side wing.
When should the wings be adjusted?
When your child's arms and shoulders require
more room within the seat, adjust the expandable
side wings to the widest position to create more
space for your child. Alternatively keep narrow if
there are width restrictions in the car.
