Hope this photo works. press the button. it should stay lit. you can also still us exhaust brake when u need it by pressing small button on end of right hand stalk
Thats the one, only on mine its the 4th button across. Just as a matter of interest,by the gear switch does it say profi,or fleet. If it says fleet then I think it is an auto only box.
“Fleet”. I’ll have another look at the console tomorrow night.
