Manual - OMSI - Omnibus simulator

You can use this menu dialogue to change the date and time as you
see fit, but only if there’s no active route. If there’s an active route,
you’ll still be able to set the time ahead, but not back.
Confirm the changes by clicking “OK”. It may take a little while for all
the AI vehicles to be moved to their new locations.
2.8. Driving the Bus
Now it’s time to flip the switch and turn the key.
You can turn on the onboard electronics by pressing [E] or by inserting
the key (1) in the ignition and then pressing the main battery switch
(2), which is directly above it. The IBIS startup chime will play and
some of the warning lights and the IBIS display will light up (3). Note
that some vehicles, like the ’77 SD200 and SD202, don’t have a
battery switch. You’ll only need to insert the key in the ignition.
You can turn the engine on or off with the [M] key or with the ignition
(4) and engine cut-off (5). You can only start the engine if the transmission
is in neutral. To turn off the engine, you must press the engine cut-off
until the engine has stopped completely – otherwise, it may turn itself
back on.
