Check this out, your maintenance required light as you say is actually just a switch that flips through 3 colors, green to yellow then to red.. All it means is that you need to change your oil and check all your other fluids.. Your check engine light however means you have a fuel or an emissions problem, usually just a sensor.. As far as the 75k thing, yea you should change your belts, but heres a better way to go about it then going somewhere and having them rob your pocket..Go to your nearest Honda dealers service department and ask for a list of all the maintenance requirements for the life of the vehicle.. It breaks it down from the time you buy the car, until about 175,000 or so.. I.E. 3000, 7500, 15000, 30000, 45,000, 60000 and so on, this little chart will tell you what is recommended at each level of milage.. Hope this helps ya and saves ya some money in the long run.. Some will tell all kinds of crap needs to be done when in actuallity it does not... Email if you got any more questions, I'd be glad to help...
