You fasten your seat belt every day without thinking about it.
Click. Go.
But have you ever looked at that little round button just above your seat belt buckle—the one nestled in the plastic housing by your shoulder?
This is not a design flaw.
This is not decoration.
And it's definitely not just for show.
This tiny button is one of the most underrated features in your car—and once you find out what it does, you'll wonder how you ever lived without it.
🔍 What is this button called?
The official name for this button is the seat belt height adjuster release button – but most people just call it the seat belt advance button or shoulder buckle release button.
And what is his task?
👉 Allows you to temporarily loosen the shoulder section of the seat belt - without having to unfasten it.
✅ What it does (and why it's brilliant)
When you press this small button, the seat belt retractor releases the tension, allowing the shoulder belt to move freely up or down – usually by about 15-30 cm.
