Vehicle is a 2021 C3 Aircross Shine Plus Automatic

Is it ok (or good/ bad practice) to use stop/start button whilst the gear lever is in the drive position?

Why the question?
When I stop the vehicle with the intention to park it:-

1.
a) Stop/start function will stop the engine
b) Putting the gearbox to park position restarts the engine
c) I then press the stop/start button to stop the engine

or to avoid this double restart I can
2.
. a) Stop/start function stops the engine
b) I then press the stop/start button (whilst gearbox is still in drive)
. c) Move gearbox lever to park position

Thanks,
Dave G

If you intend to stop and park, why not just move leaver to park position, then press stop/start? Have I missed something?

For an automatic gearbox, the Stop and Start with starter function authorises the automatic stopping of the internal combustion engine when:

First case:
  • The brake pedal is pressed when the gear selector is in position "D"
  • The speed of the vehicle is less than or equal to 3 km/h
Second case:
  • The neutral position is activated for 0,5 seconds
  • The vehicle speed is equal to 0 km/h
N.B.: The Stop and Start function authorises the automatic stopping of the internal combustion engine if the vehicle is on a gradient of between -12 and +8%.

The Stop and Start with starter function requests the automatic restart of the internal combustion engine when:

First case:
  • The brake pedal is released
  • The gear lever is in the "D" or "R" position
Second case:
  • The gear lever is in the "D", "R" or "M" position (Coming out of the neutral position).
N.B.: The Stop and Start with starter function deactivates the automatic stopping of the internal combustion engine 10 seconds after reverse gear is engaged, unless the neutral position is maintained (0,5 seconds) or if the vehicle speed reaches 10 km/h.

Ok I've just tried this.
Pulled up and engine stopped via Stop/Start still in D. Brake pedal pressed (releasing will start engine), seat belt ON (undoing will start engine), door SHUT (opening will start engine. Then pressed engine Start/Stop button. Car shut down. Then moved the gear selector to P. I then applied hand brake and released foot brake.
I also checked by releasing the handbrake that the gearbox was locked by the park pin. It was. I exited the car and shut the door and locked. Then unlocked entered and started engine. System normal.
As you say using this prevents an extra start occurring. Whether it's worth the effort remains unknown.

I thank everyone for their responses.
Unfortunately I don't think that my question has been answered. Perhaps I did not describe it well.
The question is:-
Is it good/ bad practise or will it cause any long term damage if when the selection stick is in the drive position and the car has automatically stopped the engine, for me to then press the stop/ start button thus preventing the engine from re-starting when I move the stick to the park position.

It won't do any damage at all.

I’m interested to know the reason why you want to do this?

Its to avoid the unnecessary re-start - please refer to my first posting.
As I do short journeys which involve a lot of stops I want to preserve the battery.

It sounds to me that you need to DE-ACTIVATE the stop/start in vehicle settings.
