儿童安全座椅别只看“能不能装上”：孩子尺寸、座椅说明和车辆手册要一起看

Select and use a child restraint for the child's size, the seat's limits and the specific vehicle. Read both manuals together to confirm seating position, orientation, anchorage and any support-leg or tether conditions. Do not invent anchor points or combine methods unless permitted. Record the exact seat model and check product notices and recall information. Recheck after the child grows or the vehicle or seating position changes. Avoid unapproved accessories, and verify the history and serviceability of a used seat. Online photographs cannot certify a correct installation; seek qualified help when unsure. US recommendations do not replace local rules or product instructions.
