C7 Active Fuel Management (AFM)

[BobCollins]

Disregarding Manual paddle, does AFM engage in all driving modes with the six-speed automatic transmission?

Thanks!

Cylinder deac. operates only only in the "Eco" mode.

Cylinder deac. operates only only in the "Eco" mode.

Today, I noted cylinder deactivation in ALL modes. The display would indicate "V4" if I was not climbing a hill or accelerating and would return to "V8" otherwise.

Again, this with an automatic transmission.

Thoughts?

Interesting.

What you see is what you get, apparently.

I was told by GM that AFM was enabled only in the eco mode.

Could be I have incorrectly remembered the conversation.

What's the Owner's Manual say?

Aw, Man! You mean I actually have to read the owner's manual? :eyerole

Okay, fair question! Page 9-25 has the answer: "With a manual transmission, the system is only active in ECO mode. With an automatic transmission, the system is not active in the Manual Mode."

Hib, thanks for getting me to the answer.
