What's in a service?

I cobbled a spreadsheet of the Toyota USA schedule (as outlined in the Warranty and Maintenance Booklet, a pdf of which is available at Toyota Tech Info), then extrapolated it to 260K miles, which is well beyond your 350K kms (see attached). Note, the Toyota USA schedule only goes to 120K miles, and what I've done is to continue the patterns. All that said, you should to some extent rely on your mechanic's judgment. Also, Toyota (USA at least) make no mention of a few services that are likely worthwhile, specifically transaxle fluid change (same as the transmission fluid you mentioned) and brake fluid change.

 

Yeah do that list that you just put up transmission fluid brake pad so on and so forth you'll got the basics covered there's really not much else You got the cabin air filter there and there's nothing else you need to be doing air conditioner and heat work don't mess with that stuff most people don't use their friction brakes that much but it close to 300,000 mi or 250,000 mi it's time for a fresh set of pads all the way around If you do it right you don't even have to mess with the hydraulics maybe clean off the tone rings but if there's no evidence of anything going on leave them alone.

 

if you don't know the service history of the car, do everything and then follow mendels schedule.
new air filter and cabin filters. after that, inspect, clean/replace as needed at specified intervals or more frequently.
skip brake pads unless there's a problem, but change the fluid, and all other fluids.
if you do know the service history, just follow mendels schedule.

 

the gen2 doesn't require a lot of maintenance, change the spark plugs and/or ignition coils if you noticed misfires. If not then leave them alone, they last a long time (sometimes the ignition boot only fails, they crack). Ignition coils and spark plugs are very easy DIY, you can do it even blindfolded. As for the fluids if you don't know when they got replaced it's better to have them replaced.. coolant inverter and engine, transmission and engine oil and filter. You're just waiting money on some unwanted maintenance, save that for future replacements like your inverter pump and 3-way coolant valve to fail.

 

They won't have that in Sweden so that is one less thing to worry about.

 

that is for a standard automatic transmission. prius has an eCVT which cannot slip:

exactly, simple drain and fill. remove the fill plug first in case it is stuck. that way, if you drain it, you won't be left with an unfillable transmission.
