Rear Facing Convertible Car Seat Installation- CPST

Evenflo Sonus installed rear facing in a 2015 Subaru Forester. This video is meant to demonstrate general rear facing installation rules and techniques. Always follow the instructions for your specific car seat and vehicle using both manuals during installation!
Corrections/clarifications:
I said that that a seat belt is always able to be used instead of LATCH as long as it is in working order. There are a few exceptions for certain types of seatbelts. Check your car seat and vehicle manual to be sure.
I also said that there is only one US car seat that allows both seatbelt and LATCH installation together. This was a little confusing to even include. I was referring to the Clek Foonf, but this only applies to the forward facing position.There is also one rear facing only infant seat (Nuna Pipa), so neither actually applies to a rear facing convertible.

I see you removed the strap from the white plastic tie to keep it in place when changing to rear facing position. is that allowed?
