What is the main function of a car seat's instruction manual?

The main function of a car seat's instruction manual is to offer guidance on installation, safety measures, and weight/height limits. This is crucial for ensuring that the car seat is used correctly and safely. Proper installation is vital, as a car seat that is not installed according to the manufacturer's instructions may not perform as intended in the event of a crash.

Additionally, the manual typically outlines specific safety measures that must be followed to maximize the protection of the child. These often include how to properly secure the child in the seat, as well as reminders regarding appropriate clothing and position. Furthermore, the weight and height limits specified in the manual are essential for determining when a child should transition to a larger seat or different type of restraint. Ensuring that the car seat is used within these limits helps to protect the child from potential injury.

While care tips, warranty information, and guidance on compatible vehicle models are valuable, they do not encompass the primary purpose of ensuring the seat's installation and safety during use, which is why the answer focusing on installation and safety measures stands out as the correct one.
