That light IS for your power step, although I found it useless when I had one. Having it OFF means your power steps don't come out and in automatically. Having it ON, means that your power steps will automatically retract when you start the engine. However, I found it didn't seem to matter.
Also, electric steps falter when it gets below freezing.
