It's all in the bentley.
First thing you do after reconnecting the battery is make sure it starts and everything seems ok, shut the engine off and remove the key.
1. Get in car, close door, insert key and turn to the "run" position, but do not start engine. Hold accelerator to floor for at least 5 seconds, release pedal and turn off ignition switch.
2. From outside the car, close all doors, insert key in driver's door, turn to right to roll down all the windows. Remove key. Insert key into driver's door lock, Turn to the left to roll up all the windows, remove key.
3. Recode radio if necessary (it will often come on after a couple of starts by itself in the newer cars).
4. Drive the car on a hard run a few times with the pedal to the floor in 3rd for at least 5 seconds to set the readiness code. (there's an exact procedure in the manual, but just driving it will set the code eventually in a short time too).
That's about it.
There's some kind of adaptation setup for the auto-transmission, but I don't have one so I don't know for sure the process
