You driven Volvo?

The turned arrow is a "return key" or enter button when you're going through the computer for diagnostics or whatever. The shorter lever is engine brake yes. I was never able to find a use for the buttons on the end of it.

To start a parked regen you have to go through the computer, find ATS STATUS, and hit request regen.

 

The button at the back switches the shift pattern between power and economy. If you're hauling dry freight just leave it in E. Power rarely helps you out. The button on top of the shifter just allows you to move the shifter from neutral to forward, you can't drive like that, but makes climbing into the sleeper easier. And button on the front allows you to shift positions. I don't see a second lever?

 

Don’t forget to set trailer brakes and turn off cruise before your regen. That’s how mine works. 2013 630.

 

Yeah that's baloney about the shifting. That's a company setting.

No way was I going to stop on elk that night, I got over it and slept in Laramie. Glad I did too, Sherman had been taken care of, and elk was closed all day when I woke up.

 

Brakes yeah, mine never bothered me about the cruise.

 

That just looks like the button to shift from R N D M.
The plus and minus are what was said earlier, upshift/downshift
