Warning Symbol on dashboard on 2007 Chevrolet Trailblazer

I have a picture of an oil can and a wrench, what does this mean?

As stated in your owners manual, that is the "change oil" reminder indicator. The change oil reminder should be reset each time the oil is changed. Again, the instructions on how to do so are included in your owners manual.
