Hi, I am looking for the owner and service manuals for Toyota IST 2002

SOURCE: Maintenance Toyota Solara 2000

I have kept my cars running for a long time (250k+) by changing fluids as u are doing, and fixing things right away, not letting them develop into bigger problems, so u are destined to have your car for a long time! Many of the maintenance items u list are typically NEVER done by anyone, but they should be. Here's what I recommend from many years of maintaining my cars:
ps flush-50k or 5 yrs
brake fluid flush- every time u have brakes replaced.
Rad.drain, flush, fill -new coolant is said to be good for life of car, I would flush and refill 50/50 coolant water mix every 4 years.
Fuel Injection- I'll get flak over this, but I never do anything to the system, just change your fuel filter every 2 years, or 20k
Trans Flush-don't have it done if they '**** out' the fluid from the dipstick tube. I consider that method a waste. Have the pan removed to drain it, and replace the trans filter if equipped w/ one (u can't change the filter if u **** the fluid out of the dipstick.) Also, some vehicles have a magnet on the bottom of the trans. pan, which collects fine shavings from normal wear and tear (and pieces of metal from a trans. about to go bad). U need to drop the pan to clean this crud off the magnet.
oil and filter (good quality filter-cheap junky ones are much lighter than a quality one) every 3k or twice a year whichever comes 1st
I'll add: air filter- every 20k or once a year
check tire air pressure once a month, rotate tires for even wear (every 5k miles) Can I buy your well maintained car when u r ready to sell it?

Drive it regularly and keep up with the maintenance as you have. I have an '88 Toyota P/U with 70,000 mi. on it and though it did sit up for a good while, regular maintenance has kept it running.
Power? Check the timing and if it is off replace the timing chain. That is all you can do, honestly.
Please remember to rate this solution.

SOURCE: TOYOTA COROLLA 2006 - BRAKE PROBLEMS

30% of a brake pad is still quiet a fair bit, unless you drive and use performance pads.

dealerships do say alot to make money from there customers,

if you stick to speed limits or a little bit over with no harsh braking and down gearing for cornering you will be fine with the 30% left on the pads, get them sorted when you come back though or after a week or so of being back :)

SOURCE: Toyota 4Runner/maintenance schedule at 140K miles

The maintenance schedule is an outline and should be followed if you want to keep your vehicle in good condition. the maintenance items listed in the schedule are performed at their set intervals for a reason. Manufacturers have found the wear limits on certain parts and those parts may need to be serviced or replaced at those intervals or catastrophic failures may result.

I have the 1990 model and just so happened to stumble on its unusual location today as I was replacing the door hinges. On the passenger side open the door and look above the step, there should be a little plastic cap with the wiper icon on it. hope this helps!
