I started my engine day on my 2005 crossfire, and it popped up down by the mileage. It showed looks like a little man running with a 4 digit.
where can I find a list of codes?

 

Are you sure it's not a wrench and the number 4?
That may be how many days you're passed your oil change.

 

Do you have an owner's manual? If not, you can download a free copy on this site.

 

Our cars do not display the ECU codes in that window - they SHOULD, but they don't.
You are probably seeing the FSS (Flexible Service System) warning of being past due on oil change/periodic service. If the garage that last changed the oil did not reset the FSS, you will get that alert long before the alert is legitimate.

The owner's manual talks about it, here is a bit on it from "Benzshops", a site sponsored by independent Benz garages:

But frankly, the owner's manual does a GOOD job of describing it.
