17 Mack pinnacle

[MacDragyn]

I got a 17 Mack pinnacle cxu 613, mp8 engine, automatic. It's got the guard dog system and I've scoured the manual. I got the letter P on my dashboard (in the bonus/penalty area) and I cannot figure out what it means, what caused it, how to get rid of it, or why it decreased my speed. Help is much appreciated

The letter P in a circle indicates parking brake.

No. It's not in a circle. It's on the digital display. It's cut my Max speed by like 3 mph

I believe that is the Power Leash Indicator.  Look up Power Leash in the operators manual.

It's not for braking. It's limiting my speed below the governor. Dropped me from 69 to 65mph

Your boss put a speed limit on your truck? He doesn't want you to get a speeding ticket?

(I drive mechanical trucks so ignore me. I can't offer anything useful to help you out.)

Maybe it means something in Swedish. Have you checked your setup language and set it to American and not kings English

The internet says that in Swedish P can be an abbreviation for father. Congratulations on getting your ? pregnant

You could always take it to Ikea, they might be able to understand it better that Volvo/Mack

Looks like the Fuel MPG performance bonus/penalty has been set up to lower the road speed if a certain MPG is not achieved.  These are parameters that can be turned off or adjusted by Tech Tool. Our company ordered all our CXU’s with this turned on , we later turned this off due to the amount out idle time and PTO time and stop and go driving , we could rarely get 4 mpg.

Mine just got an I on the dashboard like the photo above, what does that mean?
