I first noticed it yesterday when my car warned me my tires had low pressure. I don't think it's related to my tires though. It looks like an envelope so I thought maybe it's telling me I have unread text messages, but I don't. Anyone know what it is?
Its probably the notification that your service is due - everyone got the same notification at the exact same time on the exact same day (there's a thread somewhere about it) - it was a glitch that somehow cleared itself.
Swipe from the top (it works like an Android phone/tablet) and you can touch and read the notification.
Make sure you're stopped before you try and swipe down to read it, otherwise it probably won't swipe down. You can also read it from the Hondalink app on the infotainment system.
