Toyota Vellfire maintenance is generally very simple, and most repairs can be carried out by a trained mechanic. However, there are a few things that you should do to keep your vehicle in top condition: regularly check the oil level, change the air filter every 6 months or 12000 miles (whichever comes first), and inspect brake pads and rotors at least once per year. In addition, make sure to perform periodic drive tests to ensure all gears are working smoothly and that no underlying issues with your transmission or engine have arisen. If anything seems amiss, don't hesitate to bring your Vellfire in for service!
