The electronics on ALL the semi-auto Smarts is quite novel.....it learns your driving style.
Firstly, the factory default is always start in A from N.
If you always start in A (which is the default) then that will be your default.
If on the other hand you have always started in 1 from N, then after a while it will remember
to always select 1 when you move the lever from N into forward ('drive').
In addition, it also learns and remembers how you drive, and at what speed/revs to change up.
So if you drive hard and fast, it will after a time, remember to change up through the gears
at high engine speeds, but if you are a more gentle driver it will remember, after a while,
to change through the gears earlier.
So...on the basis that most of us are not the original owners, all the semi-auto's will be
working on settings 'learned' from the original 1st owner !
If you want to 'reset' this, you have to disconnect the battery for about 15 minutes to 1/2 an hour
so that the 'memory' is 'dropped', then reconnect the battery and it should have reset back to
the factory default (of A) and be ready to be 're-taught' your particular driving style.
As a final point, any software upgrades will flash the 'memory' to the original factory defaults.
