Installation Tips

  • read the vehicle manual
  • find a certified child passenger safety instructor or technician to help you and check your installations
Right for Newborn?
  • whether you buy an infant only car seat or an all-in-one convertible car seat, both car seats have to meet the same standard
  • seats like the Diono all-in-one convertible car seats come with an infant cushion insert (radian® 3R not included) to properly fit your child in the harness
  • all-in-one convertibles are more economical - they have a lot of room for growth for your growing child


Folding & Unfolding

  • to fold: remove the red velcro strap from behind the fabric and loosen up the harness as much as possible so they are at the top of the car seat. release the lever at the bottom of the car seat and push seat inward - secure the top with the red velcro strap.
