6. Care and Maintenance
Regular cleaning and maintenance will help prolong the life of your car seat.
- Fabric Covers: The fabric covers can be removed for cleaning. Refer to the care label on the fabric for specific washing instructions (typically machine wash cold, delicate cycle, and hang to dry).
- Harness Straps: Wipe harness straps with a damp cloth. Do not machine wash or submerge harness straps in water, as this can weaken the webbing.
- Plastic and Metal Parts: Wipe plastic and metal parts with a soft, damp cloth and mild soap. Do not use abrasive cleaners or solvents.
- CupFolders: The CupFolders are dishwasher-safe for easy cleaning.
7. Troubleshooting
If you encounter issues with your car seat, refer to the following common solutions:
- Difficulty Tightening Harness/Belt: Ensure there are no twists in the webbing and that the harness/belt path is clear of obstructions. Re-read installation instructions carefully.
- Car Seat Feels Loose: Re-install the car seat, ensuring the LATCH connectors or vehicle seat belt are pulled as tightly as possible. Check the RideRight bubble levels. The car seat should not move more than 1 inch side-to-side or front-to-back at the belt path.
- Headrest Adjustment Issues: Ensure the orange handle is fully squeezed when attempting to adjust the headrest height. Check for any debris obstructing the mechanism.
