Q: Malfunction Indicator Light on 2006 Hyundai Tucson

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When driving to work this morning, my malfunction indciator light illuminated. At first I thought I was down on oil because I was a little overdue for an oil change. The car seems fine, so what would cause that light to come on?
