Yeah, I haven't read the handbook. Can anyone else comment to confirm what's the "correct" way to do it and confirm the below happens to them too.
When you pull up and; leave it in gear 1 then switch off.
It's all good then when you start the car it says gear 1 but immediately turns to N when it's ignites
When you pull up and; put it in N then switch off.
The car beeps at you and flashes "N" on the screen.
Maybe you should,

, here is the relevant bit direct from the 500 Dualogic supplement.
ENGINE STARTING
The system permits engine start-up with a
gear engaged and also with the gearbox in
neutral (N); the brake pedal must always
be pressed first.
It is advisable to place the gear lever in
neutral (N) before starting the engine.
After start-up:
❒the gearbox automatically engages neutral (N)
❒the lever remains in the same position
as the last time the engine was turned
off
❒the display shows the letter (N) and,
when the brake pedal is released, an
acoustic signal indicates any inconsistency between the lever position and
the gear engaged
❒the gears that can be engaged are 1st,
2nd or reverse (R).
IMPORTANT If start-up is requested with
the gearbox is a position other than Nand
without the brake pedal pressed, the display shows a dedicated message see
(“Warning lights and messages” paragraph). In this case, repeat the start-up manoeuvre, pressing the brake pedal.
