What does it mean when a car says maintenance required?

The Toyota maintenance light may appear on the dashboard as “MAINT REQD”. It's a light that stays on permanently, letting you know you need to change the oil at a certified auto shop. Changing the oil in your Toyota can improve fuel efficiency and make your vehicle run as smooth as silk. The light illuminates for about 3 seconds and then flashes for about 15 seconds every 4,500 miles after maintenance has been restored.

In most cases, this just means that your vehicle may need to change the oil. The light will turn on and stay on if the distance traveled exceeds 5000 miles after resetting maintenance data. Consult a qualified automotive maintenance professional to determine the maintenance and repair needs of your vehicle.
