I was backing up today into my driveway, nothing behind me. Camera beeped and there were orange triangles with exclamation points on the screen. Any idea what this means? Can't find anything in manual.

 

For starters, you need to give more information like year and model. That said, infotainment systems can by finicky and there have been some upgrades in software over the years. Best thing is to take it back to the dealer and have them sort it out.

 

2016.5 CX5 GT. I think it was warning me of something but I don't know what.

 

Clearly it was either your cross traffic sensor or proximity sensors in your bumper (if you have them, they are circles on your bumper) going off. Weather you saw anything or not, they went off. Either you didnt see something or something caused interference.

 

It's the first I've seen them come on. There was a snow bank to my left so maybe it thought I was too close.
