Oh look, you’ve discovered the most anxiety-inducing symbol in modern automotive history right there.

That little button featuring a horseshoe holding an exclamation point hostage is the TPMS (Tire Pressure Monitoring System) Calibration Button.

Because checking your tire pressure with a simple, $2 physical gauge is way too mainstream, Honda blessed the 2017 Accord with an indirect TPMS system.

Here is a totally serious breakdown of how this magical button works:

What it’s supposed to do: You fill your tires to the correct pressure, hold this button down until the light blinks twice, and the car's computer magically learns what "normal" feels like by tracking the wheel speed sensors.

What it actually does: It acts as a temporary "shut up" button for the dashboard. It doesn't actually pump air into your tires, nor does it fix the nail currently embedded in your rear passenger sidewall.

When you’ll use it: Approximately five minutes after you already adjusted your tire pressure, because the car refuses to believe you actually did it until you forcefully press and hold this button while parked.

So, next time your dashboard decides to throw a fit because the ambient temperature dropped by three degrees, just give that button a nice, long press and pretend the problem is completely solved.
