May be dealing with a dead battery - not sure yet. Bigger concern is if the '06 Avalon XL - no smart key in this car - is a vehicle that requires a lot of special reinitializing after changing the battery?
I have located info about resetting power window system and have seen info on the power seat in an '06 service manual.
Other than these 2 items and losing the clook/radio settings, are there any snafu's an individual is likely to run into?
Thanks for your time.
