When I put my seatbelt on, the seatbelt indicator on the driver display doesn't go off until I've driven for around 15 seconds. I assumed it should extinguish as soon as the belt is engaged. The display overhead indicates right away. Not a big issue but does anyone else experience this? 2024 Astra L...

Thanks Kzaruz.

I can adjust the brightness for interior lighting but "cockpit brightness" is grayed out.
Anyone know what's meant by cockpit brightness?
