Alles anzeigenJmr44300 - Please note, not all functions can be use in every bus. As you can see in the manual, these options you can change at your bus:
"Wagennummer" means the number of the vehicle.
"Abbiegeassistent" can be a display for the death triangle or a little triangle beside the front door.
"alte Decke / neue Decke" means the ceiling in the bus
"Aussenspiegel" means the mirror outside of the bus on your right side
Thank you for your answer, I thought I had read that the bus in question was hybrid but I must have changed the page inadvertently because indeed it is not, sorry (tiredness doesn't help I will wait and hope that the option will be available in the long term).
On the other hand for the 4 translated setvars, I can press on them but it does not change in game, I have to restart OMSI each time by changing the setvar at the same time to have these options, I don't think it's normal (except maybe the ceiling with the modification of the intensity of the lighting, yet I can still click on the button without OMSI changing anything, unlike the ATRON, klima, LED signs... which them, are changed in the second in game)
