    Hi all,
    I just bought a 2001 Prius Model III and want to make sure it stays reliable for years. Are there any maintenance tips or common issues specific to this model that I should be aware of? Any advice from experienced owners would be awesome!

    Change coolant (engine and inverter), transmission oil (use only Toyota T-IV), spark plugs (Denso SK1611 Iridium), serpentine belt, for starters. Maybe gas tank filler cap. Change engine oil (5W-30) and oil filter. Engine air intake filter. Cabin air filter. These are some of the items I've attended to on my '02 w/173K miles. YMMV.
