Final answer:
Before installing a child safety seat, it is important to read both the child seat instructions and the vehicle owner's manual.
Step-by-step explanation:
True. Before installing a child safety seat, it is important to read both the child seat instructions and the vehicle owner's manual. This is necessary to ensure the seat is installed correctly and securely.
Child seat instructions provide specific guidelines on how to properly install and use the seat. They include information on how to position the seat, how to secure it with the seatbelt or anchor system, and how to adjust the straps and harnesses.
The vehicle owner's manual, on the other hand, provides information on how to use the seatbelt or anchor system in the vehicle, as well as any specific requirements or recommendations for installing a child safety seat in that particular vehicle.
