maintanence required

You guys kno when you start your car up..the stuff in your gauge panel lights up like the check engine, maintence, oil and all that stuff? its suppose to go away for like 3 seconds after u start the car but my maintenance require light stays on and starts blinking but disappears after 10 second.

does that mean something is wrong is does that mean it just goes on every certain miles on the odometer? do I need to take it in or something?
