2.1 General Safety Guidelines
- Always ensure the car seat is correctly installed and secured before placing your child in it.

- Ensure the child's harness is snug and correctly positioned, with no twists.
2.2 i-Size Compliance and Usage

5. Operating Instructions
5.1 360° Rotation

5.2 Harness Adjustment (40-105 cm)
For children using the 5-point harness:
- Loosen Harness: Press the harness release button (often located under a flap at the front of the seat) and pull the shoulder straps forward to loosen.
- Place Child: Position your child in the seat.
- Buckle Up: Bring the two buckle tongues together and insert them into the central buckle until you hear a "click."
- Tighten Harness: Pull the harness adjustment strap (located at the front of the seat) until the harness is snug against your child's body. You should not be able to pinch any slack in the shoulder straps.
- Adjust Headrest: The headrest and shoulder straps adjust simultaneously. Pull the headrest adjustment lever (usually at the top of the seat back) and slide the headrest up or down so the shoulder straps are at or just below your child's shoulders when rear-facing, or at or just above their shoulders when forward-facing.

5.4 Recline Positions
The car seat offers multiple recline positions. To adjust, locate the recline lever (usually at the front or side of the base), pull it, and tilt the seat to the desired angle. Ensure it locks securely in place.
