30,000 mile service checklist
Here's exactly what your factory maintenance schedule calls for at this mileage — and what each item typically costs.
30,000 mile service
- Engine oil and filter change (0W-16 full synthetic)
- Tire rotation
- Replace engine air filter
- Replace cabin air filter
- Inspect spark plugs — iridium, Toyota factory long-life interval ~120,000 mi; do not replace at 30k
- Replace brake fluid — Toyota Super DOT 3 (Toyota calls for change based on time/contamination; many shops use 30k as a practical checkpoint)
- Inspect engine coolant and hybrid inverter coolant levels and condition
- Inspect accessory drive belt for cracking or glazing
- Inspect suspension, steering components, and CV boots
