Adjusting for Fit:
- QuikFit Headrest: Use the one-handed adjustment mechanism to raise or lower the headrest and harness system to the correct height for your child's shoulders. No rethreading is needed.
- ReclineFit: Select one of the 3 recline positions to ensure your child is comfortable and the car seat is properly angled for their age and the vehicle's seat.

Troubleshooting
If you encounter any issues with your Maxi-Cosi Pria All-in-One Convertible Car Seat, please refer to the following common troubleshooting tips:
- Loose Installation: Re-read the installation instructions carefully. Ensure the LATCH connectors or vehicle seat belt are routed correctly and tightened securely. The car seat should not move more than one inch at the belt path.
- Harness Too Tight/Loose: Adjust the harness straps using the front adjustment strap. Ensure the harness is snug against your child's body, with no slack, and the chest clip is at armpit level.
- Headrest Adjustment Issues: Ensure no fabric or debris is obstructing the QuikFit mechanism. Apply firm, even pressure when adjusting.
- Buckle Difficulty: Check for any food crumbs or debris in the buckle mechanism. Clean as per maintenance instructions.
- Child Discomfort: Verify that the car seat is in the appropriate mode and recline position for your child's age and size. Ensure infant inserts are used or removed as needed.
