Does anyone know what these switchs do on a mercedes arocs 26t grab
Searched high and low and cant find anything about them!
Pure educated guesswork; far right is a work light. The other three to control air suspension to individual axles, i.e. lift.
If you’re struggling for power on a hill, press the 12V button to engage all 12 cylinders in the engine. They upgraded the V8 engines about 3 years ago to V12.
The bottom part of that button is for the shower.
The buttons with 1,2, and 3 are your gears. It goes into auto after 3rd gear so no need to worry about gear changes once up to speed.

Defently struggling with power on the hills, and on the flat thinking about it 
You need an air duster and a can of Mr Sheen mate.
