overdrive off on 1995 Ford Explorer

my truck is flashing overdrive off, thats a problem? i thought i should just push the button to turn it on. do i need to fix it or can i just ignore it?
Also, my truck just started leaking power steering fluid could this just be the lines or does the whole pump need replacing?
