Yes, The ECU has to re-learn your driving habits. ;) Thanks for the answer. boy boy I had to reset the seats settings, service warnings, tire pressure warning and radio settings. I wish that the dealer had warned me about all of those things and not to have to find something new every day.

After dealer changed defective battery (under waranty) the mileage of my 08 ES350 changed. I used to get 29-30 on highway and 25-27 city highway combined, now I get 25 highway and 22-23 city highway combined. Can the change of battery made any changes to the computer settings ?.

I also hated the outside antena and was not very happy with the idea of moving it to the inside of the rear glass so I tried something else. Take it out from the top of the trunk and reverse it to the inside of the trunk. Be sure that you move it to the metal and not to the insulation. My reception is the same that I had before the move, it looks that the trunk metal acts like a dish. I did it over a week ago and I get good reception everywhere that I go. Macho

I have my ES350 08 since November 2007 and I am very please with the car. The transmission sometimes downshifst hard. My only complain is that when the car is cold you can hear the valves making a ping noise which stop after it gets warm.
