Proper installation of a rear facing car seat is critical for its effectiveness. Here are some key steps: 1. Place the car seat in the back seat of the vehicle. 2. Use either the LATCH system or the vehicle's seat belt to secure the car seat. 3. Ensure the seat is at the correct recline angle to keep the child's airway open. 4. The harness should be snug and positioned at or below the child's shoulders.
