HOW TO INSTALL CHILD HARNESS
D. Hook the SecureGuard™ Device over the lap belt
and engage the vehicle seat belt tongue to the
buckle. Check and adjust the seat belt to sit firmly but
comfortably around the child's pelvis. The seat belt
buckle should be located as low as possible below the
child's hip.
E. If the child harness extension strap is used, adjust this
before removing slack from the child harness. Ensure
to keep it as short as possible while allowing the child
harness to be adjusted to suit the child.
F. With the lap belt (or converted lap/sash) and
SecureGuard™ adjusted to be a firm fit on the child's
thighs, adjust the Child Harness to remove all slack
in the shoulder straps. Lap belt must be adjusted
first so the lap belt is not lifted off the child's lap
when the harness is adjusted. Once adjusted, further
adjustments are necessary only to accommodate the
growth of the child.
G. Finally, roll up the free end of the harness adjuster
strap, place it on the top of the adjuster and secure
using the storage strap. Close the cover pad.
Always secure the loose end of the top tether strap to
prevent it hanging out of the car or being accessible
by the child.
H. Lengthen the harness at any time by fully pressing the
Adjuster Button (1) whilst pulling the shoulder strap (2)
upwards.
