6. Maintenance

  • Seat Pad: The seat pad is machine washable. Refer to the care label on the fabric for specific washing instructions.
  • Harness Straps: Wipe harness straps with a damp cloth. Do not machine wash or submerge in water, as this may weaken the straps.
  • Plastic and Metal Parts: Clean plastic and metal parts with a soft, damp cloth and mild soap. Do not use abrasive cleaners or solvents.
  • Buckle: Periodically check the buckle for debris. Clean with a damp cloth if necessary.

7. Troubleshooting

If you encounter issues with your Chicco KeyFit 35 ClearTex Infant Car Seat, please refer to the following common solutions:

  • Difficulty Tightening Harness: Ensure the harness straps are not twisted and are routed correctly through the slots. Check for any obstructions under the seat pad.
  • Car Seat Base Feels Loose: Re-check the installation steps for both LATCH and vehicle belt methods. Ensure the SuperCinch tightener is fully engaged or the vehicle belt is pulled taut, and the bubble level-indicators are correct.
  • Carrier Not Clicking into Base/Stroller: Ensure the base or stroller attachment points are clear of debris. Verify the carrier is correctly aligned before lowering it.
  • Stuck Buckle: Check for food or debris inside the buckle. Clean with a damp cloth.
