2020 Toyota Prius Prime maintenance schedule
Schedule type: fixed
Toyota sets a service visit every 5,000 miles or 6 months, whichever comes first. The 2020 Prius Prime guide lists an engine oil and filter change every 10,000 miles or 12 months; at the in-between 5,000-mile visits Toyota says to change the oil and filter too if 0W-16 oil was not used at the last change. Every visit also covers a tire rotation, a visual brake check, wiper and fluid-level checks and a floor-mat check. The 'MAINT REQD' / 'OIL MAINTENANCE REQUIRED' message is a reminder to reset after each 5,000-mile service, not an oil-life sensor. Summarized in our own words from the source listed. Always follow the owner's manual or your dealer for your specific vehicle (VIN, engine, and options).
Checked against the official document for model year 2020; other years in this range are assumed to follow it. Confirm in your owner's manual.
