Longer 5 point harness usage

How to install your Radian 5 forward facing

The Diono Radian 5 multi-stage car seat allows for longer 5 point harness use when forward facing. Radian 5 can be used forward facing from 9kg – 25kg. Keeping children in a 5 point harness beyond standard milestones and capacity limits helps ensure maximum containment and comfort while providing complete head to hip protection.

Before you head out to the car

  1. Adjust the 5 point harness to the right height for your child
  2. Undo the straps from the yoke and pull the shoulder harness through
  3. Re-slot the straps in the appropriate hole for proper fit, then reconnect the straps to the yoke
  4. Radian 5 has five shoulder harness and two crotch strap positions for flexibility
  5. Set the head rest to the right height. The expandable sides and extendable headrest of the Radian 5 are designed to grow with your child

  3. Feed the seat belt through the tunnel and secure the buckle

  5. Feed excess belt into the retractor and attach the lock-off clip on the door side to both parts of the belt

  7. Feed the shoulder belt through the top belt guide nearest the door
  8. Find the tether anchorage point in the boot. Refer to your vehicle manual for additional details.
  9. Clip the tether onto the anchorage point and pull the tether tight until the indicator turns green
  10. Check again for movement. Hold the car seat at the base and attempt to shift its position. The seat should move less than an inch side to side

  4. Re-attach harness straps to the yoke
  5. Feed the metal end of the supergrip harness through the same slot as the strap
