Yesterday afternoon, i turned the key with the intention of starting the car, but apparently it didnt start, like it didnt ignite. I didnt know that for some reason, i thought it was on, so i pressed the brake and changed the gear to Drive out of Park. The next thing i know, the A/T Oil light (red) was on. Ive switched out of park many times before without the car being started and ive never seen that light. In this situation, it didnt turn on and then turn off like usual. It just stayed lit. So then i turned the key to OFF after switching to back to park. I started the car regularly, and it took a little more time than usual, but it started and nothing was lit anymore.

Anyone know what happened?
