The 1992 Dodge Dakota 3.9L doesn't have a traditional "maintenance light" in the same way many newer vehicles do. There's no single light that illuminates for scheduled maintenance. Instead, you'll rely on the owner's manual's recommended service intervals for things like oil changes, tune-ups, etc.
There's no button or procedure to "reset" a maintenance light because one doesn't exist. You're responsible for tracking maintenance yourself based on mileage and time. Keep good records of your service intervals.
