I just got a Cl and the maintanance required light is on. I don't know if it was on before but I jus noticed it. My dad said he changed the oil yesterday. What else could it be?

The "Maintenance Required" function (it's not really a light, nor is it hooked up to any engine funtion) is just a reminder that a 7500 mile service period is due. You can reset it by inserting your ignition key (pressing it into the reset area next to the red light). This will reset the button to green.

I'm so dumb. The light wasn't even lit. It just looked like it. I noticed my mistake when I pulled into my garage (cuz it's dark and if it was really lit you'd be able to tell.
