Hello all, I had a chance to disconnect the battery, but for only like 5 minutes, maybe less. The only changes I noticed after reconnecting were:
- average mpg/mpg after refueling display reset to zero
- clock being a different time
- the mirror buttons turning off (auto fold/auto tilt down)
But oddly enough my radio presets were intact!
Isn't that supposed to be the telltale sign of a full reset?
My main concern is I would prefer if the car forget what it learned about previous driving habits. Is 5 minutes enough for the computer to fully erase its memory and relearn?

If you want to erase the CPU memory of prior driving habits, then leave your battery disconnected for about 15 minutes.

You don't even need to remove the battery cable. Just pull both the EFI1 & ETCS fuses from the fuse box in the engine compartment for 3~5 mins. This should do the trick without losing any settings.
