What to know
The rotating Sirona S is certified for 10 years from the date of manufacture. The US version is not FAA certified for aircraft use.
The date of manufacture is on the seat itself. The date of manufacture and expiration information are on a sticker on the seat; on infant seats it is on the bottom of the carrier. The period of use is also stated in the instruction manual.
Safety note: SeatCheck summarizes manufacturer and NHTSA guidance, but the label on your own seat and its manual are the final word. When in doubt, contact the manufacturer with your model and serial number.

Frequently asked questions
How long is the Cybex Sirona S good for?
The Cybex Sirona S has a useful life of 10 years from its date of manufacture. The exact date is printed on the seat's own label, so check the sticker on the shell or base rather than counting from the purchase date.
Where is the expiration date on the Cybex Sirona S?
The date of manufacture and expiration information are on a sticker on the seat; on infant seats it is on the bottom of the carrier. The period of use is also stated in the instruction manual.
Should I replace the Sirona S after a crash?
Cybex advises replacing a car seat that has been involved in an accident, because hairline cracks in the plastic can be invisible while still compromising protection. US manuals instruct owners to stop using a seat after a crash; contact Cybex or the retailer with the crash details before reusing any Cybex seat, and lean on your auto insurance for the replacement.
