If i'm not mistaken, that's just what it does. The "Maint. Req'd" light is, as Dr0lds said, activated by mileage, and nothing else, so you don't really have to worry about it. It blinks 10 times after you turn the car on just to let you know to take it in for regular maintenance.

just to expand on what Dr0lds said, to reset this light, if you look in the driver's side footwell, and look up on to the back of the panel right below the steering column (parallel to your lower legs when you're driving), you'll see a little blue button...when your car's on, wait for the light to go out, then press this button until the light lights up then dies again, and poof, it's reset.

here's a pic of what you're looking for:
