Quick answer
Before using your Metro 3 car seat adapter for the first time, complete a visual and audible check to confirm the adapter is securely attached to the stroller frame and that the car seat clicks into place without any wobble.
Why a pre-use check matters
A loose or misaligned car seat adapter can create an unstable ride for your baby. Even though the Metro 3 adapter is designed for quick, color-coded attachment, a quick inspection before each use—especially the first—helps you catch any installation errors or manufacturing defects before they become a safety issue.
What to look for (and what is normal)
The adapter should slide onto the stroller frame and produce a firm click when fully seated. The color-coded indicators help you confirm alignment, but they do not replace a manual check. A slight wiggle of the adapter itself is normal, but the car seat must not move independently once locked into the adapter.
Safety check diagnosis
- Symptom: The car seat adapter does not click into place, or the car seat wobbles after attachment.
- Likely cause: The adapter is not fully seated on the stroller frame, or the car seat is not correctly aligned with the adapter's locking mechanism.
- Corrective action: Remove the adapter and reattach it, pressing firmly until you hear a distinct click. Then attach the car seat, ensuring it locks into both sides of the adapter. Gently tug the car seat upward to confirm it does not release. If the adapter still does not click or the car seat remains loose, stop using the adapter and contact Ergobaby support.
- Stop or choose another option: Do not use the adapter if the car seat can be detached without pressing the release button, or if any part of the adapter appears cracked or deformed. Consider a different car seat model that is listed as compatible with the Metro 3 adapter.
