Can’t seem to find the Jake break button on a 2015 Cascadia

I recently started driving a 2015 freightliner cascadia DD15 automatic and I can not find the engine break switch anywhere . My previous truck was a 2016 freightliner and it was next to the regen and engine shutdown switch .

Any advice here ?

 

Button on the steering wheel.

That one effed me up too lol.

 

Isnt it the built into the shifting joystick? Pull it down like you would shift an automatic car, but each click intensifies the jake brakes instead of shifting.

 

Might not have an engine brake,,these days all unnecessary options are eliminated. I never understood that mindset, with brake jobs in the thousands.

 

I have a 30 Cascadia and it's the right lever on steering wheel column.
pull it down like you would your turn signal.
3 levels. all the way up to turn it off

 

Now you’ll have your...Jack Break.
