In the first, the extender clicks happily into the car's buckle, but the Model 3's own belt tongue then refuses to lock into the extender because it is too short to engage the mechanism. In the second, the car's tongue goes in far enough to press the extender's release button from the inside, so it will not stay latched at all.\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14.5px; line-height: 1.6; color: #4a2b2b;\"\u003eWorth knowing that parts sold as fitting the Model S rear seats have been reported as failing in the Model 3, so a Tesla-wide claim is not good enough.

The owner's manual does carry one explicit instruction, repeated across the Model S, Model 3, Model X and Model Y: never use a seat belt extender on a belt that is securing a child safety seat or booster seat. Use the ISOFIX and i-Size anchor points instead, noting Tesla's own limit on combined child and restraint weight.\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14.5px; line-height: 1.6; color: #5a4a2a;\"\u003eOne further detail from the manual is useful when you test your belt. Every passenger position has an automatic locking retractor, so pulling the webbing all the way out engages a ratchet that will not release until the belt is unbuckled and fully rewound.

The Model 3's rear belt tongue is shorter than the front one, so it slides into the extender without reaching the locking mechanism. A related version of the same fault has the tongue pressing the extender's release button from the inside, which means it refuses to stay latched even when it feels seated. Neither is safe to use. Stop using it, tell us which row it was intended for, and send a photograph so we can match the correct part.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #e5e7eb; border-radius: 10px; margin: 0 0 10px 0; overflow: hidden;\"\u003e\n\u003csummary style=\"display: block; list-style: none; padding: 16px 18px; cursor: pointer; font-size: 15.5px; font-weight: bold; color: #1a1f24; background: #ffffff;\"\u003e\u003cspan style=\"display: inline-block; width: 28px; height: 28px; border-radius: 50%; background: #7f1d1d; color: #ffffff; text-align: center; line-height: 28px; font-size: 14px; margin-right: 12px;\"\u003e3\u003c\/span\u003eCan I Use One With A Child Seat Or Booster?\u003cspan style=\"float: right; color: #7f1d1d; font-weight: bold;\"\u003e+\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 6px 18px 18px 58px; font-size: 14.5px; color: #555a60; line-height: 1.65;\"\u003eNo, and the instruction comes from Tesla rather than from us. The Model 3 owner's manual states plainly that a seat belt extender must not be used on a belt being used to install a child safety seat or booster seat, and the same warning appears across the Model S, Model X and Model Y manuals. Use the ISOFIX and i-Size anchor points fitted to the second row instead, observing Tesla's limit on the combined weight of child and restraint. Some booster manufacturers stay silent on extenders, which is not the same as permitting them.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border: 1px solid #e5e7eb; border-radius: 10px; margin: 0 0 10px 0; overflow: hidden;\"\u003e\n\u003csummary style=\"display: block; list-style: none; padding: 16px 18px; cursor: pointer; font-size: 15.5px; font-weight: bold; color: #1a1f24; background: #ffffff;\"\u003e\u003cspan style=\"display: inline-block; width: 28px; height: 28px; border-radius: 50%; background: #7f1d1d; color: #ffffff; text-align: center; line-height: 28px; font-size: 14px; margin-right: 12px;\"\u003e4\u003c\/span\u003eWill A Model Y Or Model S Part Fit?\u003cspan style=\"float: right; color: #7f1d1d; font-weight: bold;\"\u003e+\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 6px 18px 18px 58px; font-size: 14.5px; color: #555a60; line-height: 1.65;\"\u003eNot reliably, and a seller claiming to fit every Tesla is a warning sign rather than reassurance. Belt hardware in these cars varies by seat position and by build year, and owners have specifically reported parts that worked in Model S rear seats failing in the Model 3.

Read your owner's manual alongside the safety notes supplied before use. Extenders are only for people who cannot otherwise fasten the standard belt. Unclip yours when the seat is empty, since the Model 3 monitors occupancy and belt status. If it does not fit, return it within the guarantee window for a refund, though a photograph first usually saves the round trip.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Seat Belt Extenders UK","offers":[{"title":"25cm Black Rigid Extender","offer_id":59575565287756,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true},{"title":"25cm Grey Rigid Extender","offer_id":59575565320524,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true},{"title":"25cm Beige Rigid Extender","offer_id":59575565353292,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true},{"title":"12cm Black Rigid Extender","offer_id":59575565386060,"sku":null,"price":15.0,"currency_code":"GBP","in_stock":true},{"title":"12cm Beige Rigid Extender","offer_id":59575565418828,"sku":null,"price":15.0,"currency_code":"GBP","in_stock":true},{"title":"12cm Grey Rigid Extender","offer_id":59575565451596,"sku":null,"price":15.0,"currency_code":"GBP","in_stock":true},{"title":"23cm Regular Extender","offer_id":59575565484364,"sku":null,"price":20.0,"currency_code":"GBP","in_stock":true},{"title":"36cm Universal Extender","offer_id":59575565517132,"sku":null,"price":25.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1077\/0582\/7660\/files\/tesla-model-3-25cm-black-rigid-seat-belt-extender.webp?v=1793085492","url":"https:\/\/seatbeltsextender.co.uk\/products\/tesla-model-3-seat-belt-extender","provider":"Seat Belt Extenders UK | ECE R16 Certified","version":"1.0","type":"link"}
