I have a question about the energy flow meter on the 2008 Highlander Hybrid. I am talking about that square screen type display that you see on the Prius. In the pictures, I have seen it on the 2008 Highlander Hybrid. However, I am not sure if it comes standard on the base model and the limited or if it is an option you have to pay extra for on one or both. I have checked the Toyota web site and that did not answer my question. I would appreciate any help you could give me.
