Attach the Car Seat Adapter to the Stroller

  1. Locate the designated attachment points on your stroller frame, usually near the seat area.
  2. Align the adapter’s connectors with the mounting points, ensuring the color-coded dots or guides are matched correctly.
  3. Push the adapter until it clicks into place, confirming it is securely attached on both sides.

Install the Car Seat onto the Adapter

  1. Position the car seat over the adapter, ensuring the seat’s rear is aligned with the attachment points.
  2. Firmly press down until you hear a click or feel the seat lock into place.
  3. Check the connection by gently tugging the seat to ensure it’s securely attached.

Troubleshooting Common Issues

  • If the seat wobbles or feels loose, remove and reattach, ensuring the adapters are fully engaged.
  • If the adapter doesn’t click into place, check for debris or misalignment, and clean or realign as needed.
  • Ensure the car seat is compatible with your adapter, and that all parts are installed according to manufacturer instructions.

Final Safety Check and Tips

Once installed, give the car seat a firm tug to confirm it’s locked in securely. Always follow your stroller and car seat manufacturer’s instructions for safety. Regularly check the connection during use, especially after folding or adjusting the stroller.
