2014 Check engine and other lights

Hey all, got another quick question for ya. Was sitting somewhere in the truck for a while so I stopped running the engine and just turned the electronics on. I noticed that while doing this, the check engine light and a couple others come on. They don't, however, come on while the engine is running. Any clue as to what's up here? Thanks in advance!

 

Sounds normal to me?

If they aren’t on with the engine ON. I would not worry about it.

 

Alright, thanks. My first time owning a vehicle so I get a little nervous with stuff sometimes.

 

No problem.
Enjoy the truck.

 

It's normal for some or all warning lights to be on key on engine off depending on the vehicle, as long as they all go out when the vehicle is started your good.
