The oil light came on while driving the 2012 XV at high speed. I went to the repair shop, and they said it's burning oil. What should I do?

I have a 2014 used XV, and the USB port in the armrest doesn't recognize P3 and P4 USB drives. The DVD also can't play videos. I don't have the manual, so I'm not sure if this navigation unit doesn't have these functions or if there's a malfunction.
