My Toyota dealer has computerized rthe maintenance schedule for every model and year. They will gladly print off the pages with the applicable activities required.
Having said that, in 1998 Toyota probably had a separate little book with those tasks. My 2007 has such a booklet. It's called the "Owner's Manual Supplement" and covers "Warranty, Maintenance, & Roadside Assistance Information".
When you get down to driving only 3000 miles per year, You have to go by the TIME schedules rather than mileage maintenance. I would change oil twice a year, spring and fall, and flush the cooling system every 6 years or so. Transmision fluid & filter changes every 6 years.
My 92 year old mother in law maintains her Pontiac Sunbird exactly the same way. If the car has ABS, I would change the brake fluid every 5-6 years as well. The best "tune up" for your car is a brisk drive of 40 miles on the freeway or Interstate at the legal speed limit.
In other words, manufacturers don't count on anyone driveing this little and as a result you will likely "over maintain" if you follow the manual to the letter.
