Ok, without the info I asked, what BOTh means is this. After about 5000 miles the message and warning triangle come on. This only means the required maintenance needs to be performed like oil change etc, Then? the system is reset. Its nothing to worry about. Its all about the vehicle maintenance like oil change reminder, You are safe to drive it, just be sure to have oil change if it has been awhile then? to reset? here are 2 links to directions on how to do the reset and the warnings will go off
