The windows are simple: Press and hold the window down button until the window is all the way down AND you hear a faint "Click" inside the door. Then hold the switch up and do the exact same thing, let it close and hold it until you hear a click. This is to relearn the auto up/down features. It may require you to do it a few times if it does not take the first time. Do that for each door.

The parking brake is not too much different. With the car running, in park, hold down the foot brake pedal and apply the electronic brake (you will feel the pedal go further down under your foot). Then release the electric brake. Repeat that process for 3 or 4 times and it should be good.


That's it.


I have never actually replaced my battery but have disconnected it several times for brake service and terminal cleaning.
