Go to Honda.com, click on owners link, and register your Prelude. I've done that, and it's very easy to do (just need your vin and basic personal info). Once you're in, you can not only check the maintainance schedule, you can actually keep your own log and it will keep it on file. If you properly update it when you have the service done, each time you log in, it will tell you when your next interval is due. VERY cool! It will also give you any warranty or recall notifications the second they are released from the mfg., even before they send out the notices.
