New to forum! What's with this car?
 

Hello mini enthusiasts!
I write to you as an ambassador from a jeep and BMW background. I've recently been bestowed a 2013 Mini Cooper base and i have so many questions. I've not owned a car newer than 2001 so bare with me.

THe car is an automatic but there is a delay when letting off the brake. I am assuming this is hill assist but why on an automatic?
Sometimes it is active and sometimes it isn't so I don't know what to diagnose.
There is a triangle with an excalamation point next to my odometer. I've searched and it could be anything. The car is also low on gas at the moment so maybe it will go away after a fill up.

That's what I've got so far. Any and all help is appreciated. Thank you!
