HOW TO INSTALL USING ISOFLEX CONNECTORS
If the car's upper anchorage fitting is behind the vehicle seat back you may need to use an extension strap
as part of the top tether installation.
IMPORTANT: If using an Extension Strap, positioning the attachment clip above the child may lead to
injury in an accident therefore make sure that the attachment clip is not positioned in front of the vehicle
seat. Use a shorter extension strap or no extension strap.
Attachment clip should not be in
front of the vehicle seat front.
It is normal to have some sideways movement if the headrest end is pushed sideways. A firmer fit can be
achieved by applying more force to the ISOFLEX straps. If the tether strap is over tightened then the angle
of the seat may be affected.
IMPORTANT :
The Top tether strap must be fitted at all times when the baby is in the car when using either the
seatbelt or the ISOFLEX connectors.
Always secure the loose end of the top tether strap to prevent it hanging out of the car or being
accessible by the child.
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.
ALWAYS ATTACH TOP TETHER HOOK AND REMOVE SLACK IN THE TOP TETHER STRAP.
