When does cylinder deactivation occur with 1.5L engine?

[thomasm23]

I have a 21 OB with over 50,000 mostly highway miles. I use Eco mode quite often.

When does cylinder deactivation occur? I do not seem to ever experience any changes. Of course, there is no indication of when this occurs on the dash.

If it’s anything like GMs implementation it should occur during cruising, deceleration and idling (when Auto Start/Stop is not engaged).
