If you own a Toyota Matrix you need to know how to reset the MAINT REQD (maintenance required) light. If you call the dealer, they will have you bring it in and charge you for stuff you don't need! This light comes on after 5000 miles. Mileage is what triggers it. It is NOT triggered by the car detecting that something is wrong or in need of attention, like the check engine light. Save yourself some money and reset it yourself.
