Has anyone else with the hybrid noticed the blue band around the speedometer and how it lights up brighter while your driving.

I don't know for sure but wounder if it is to show the condition of the battery or something.
It took me awhile but I kept noticing the band not being there at all after I just started the car and then after some time the blue band appears then later it would get yet brighter.
If anyone knows for sure what this indicates, please share.
Bob
