Thank you for choosing the Maxi-Cosi Spinel 360 Car Seat. This car seat is designed to provide maximum safety and comfort for your child from birth up to approximately 12 years (0-36 kg). Featuring a 360-degree rotation function, multiple recline positions, and ISOFIX installation, it offers convenience and adaptability as your child grows. Please read this manual carefully before installation and use to ensure proper operation and the safety of your child.
2. Safety Information
Always prioritize your child's safety. Failure to follow these instructions can result in serious injury or death.
- Weight and Age Limits: This car seat is suitable for children from 0 to 36 kg. Always ensure your child is within the specified weight and height limits for the current configuration (rear-facing or forward-facing).
- Rear-Facing Position: For optimal safety, keep your child in the rear-facing position for as long as possible, up to the maximum weight/height limit allowed by the seat (typically up to 18 kg or specified by local regulations).
- Forward-Facing Position: Only use the forward-facing position when your child has outgrown the rear-facing limits.
- Harness System: Always secure your child with the car seat's internal 5-point harness system until they reach the weight limit for the harness (typically 18 kg). After this, the car seat transitions to a booster seat using the vehicle's 3-point seat belt.
- Installation: Always install the car seat using the ISOFIX system and the support leg. Ensure all indicators show correct installation before every journey.
- Airbags: Never install a rear-facing car seat on a front passenger seat equipped with an active airbag.
- Damaged Seat: Do not use the car seat if it has been involved in an accident, even if there is no visible damage. Replace it immediately.
- Supervision: Never leave your child unattended in the car seat.

6. Maintenance
6.1 Cleaning the Fabric Covers
The fabric covers are removable and washable. Refer to the care label on the fabric for specific washing instructions (e.g., machine wash cold, delicate cycle).
- Removal: Carefully unfasten all clips, elastic loops, and Velcro attachments to remove the fabric covers.
- Washing: Wash according to the care label. Do not tumble dry.
- Reattachment: Ensure covers are completely dry before reattaching them to the car seat. Make sure all harness slots are correctly aligned.
6.2 Cleaning Hard Parts
The plastic and metal parts of the car seat can be cleaned with a damp cloth and mild soap.
- Do not use abrasive cleaners or solvents.
- Ensure all parts are dry before reassembly or use.
7. Troubleshooting
If you encounter any issues with your Maxi-Cosi Spinel 360 Car Seat, refer to the following common problems and solutions:
- Car seat feels loose after installation:
Solution: Recheck that the ISOFIX connectors are fully engaged (green indicators visible) and pushed firmly against the vehicle seat. Ensure the support leg is extended correctly and its indicator is green. - Harness is difficult to tighten or loosen:
Solution: Ensure the harness adjustment button is fully pressed when attempting to loosen. Check for any twists in the harness straps behind the seat. - Seat does not rotate:
Solution: Ensure the seat is not in a reclined position that obstructs rotation. Check that the rotation handle/button is fully engaged. The seat may need to be in a specific upright position to rotate. - Headrest/Harness adjustment is stiff:
Solution: Ensure no fabric or debris is obstructing the mechanism. Apply gentle, even pressure when adjusting.
If the problem persists, contact Maxi-Cosi customer support.
