Another Cruise Control question
Howdy, Folks.

Hoping you can provide an answer because the Freightliner folks are stumped.

I have a 2016 Cascadia and still trying to get used to locating knobs and switches after spending the last 9 years in an '07 ClassicXL. My problem is the cruise control does not disengage when depressing the clutch pedal until after the clutch is engaged (disengaged?) causing the engine to over rev during the downshift. Only an issue under torque when climbing a hill. Work around is cancelling the cruise control at the switch prior to downshifting but this is sometimes inconvenient and a little frustrating.

I expect the cruise control to disengage sometime during the free play travel on the clutch but this is not happening. Explaining the issue to the shop folks in an unnamed Freightliner facility in Pacific, WA and it quickly became apparent that I did not know what I was talking about and perhaps needed to learn how to drive.

Hope I did not lose anyone in my ramblings. Anyone have any thoughts?

RE:Another Cruise Control question
Hello, I've been spoiled for the last year in my Detroit DT12 automated manual transmission so I've probably already forgotten how to shift gears. Anyway, from what I remember on my Eaton Fuller 10 speed in my old Casacadia, I couldn't use cruise while shifting. I only set it once I got into high gear at cruising speed.

RE:Another Cruise Control question
You may have a faulty clutch switch. Try idling up the engine in neutral. Then "dump" the clutch. It should return to normal idle. This may seem silly, but I have seen it. Where is your right foot? I have seen drivers rest their right foot on the accelerator while in CC. Just a couple of ideas. Using the clutch should cancel the CC.
