Buttons around the engine on/off button what do they do?

there are some weird buttons ive wondered what they were supposed to do but i cant find anything on them and when i click on them they dont seem to do anything
its the buttons surrounding the engine on/off button on vanilla beam ng its like wheenaxlefl and br or whatever and there are a few more pls help im very curious :3 and the rangebox button i guess is for off road rockcrawling but thats [the only one i know what it does

 

Some of the buttons are for locking hubs, locking differentials, changing between high/low ranges, and switching between 2WD and 4WD.

 

To add on, some of the buttons don't have noticable effects until you are offroad unless you know what to look for.

 

aaah nice but why would you want to lock the hubs can you take the wheels off or something?
