I have watched the bars that indicate the status of the Hybrid batteries change from the color green to the color blue for no apparent reason. Is this a glitch or is there a reason the bars change colors. They just change at random occasionally and the change is not triggered by the addition or disappearance of a bar, i.e. it may show 6 bars before the change and still show 6 bars after the change. I've tried to locate something in the owner's manual to explain but to no avail.
Thanks
