DFCO will start anytime you're (or Cruze Control) off the throttle and the RPMs are above 1500. The manuals will enter DFCO in about 2 seconds. The automatics in about 4. This means you need to let off the gas enough over 1500 RPM to ensure the car remains above 1500 RPM for the 2 (4) seconds it takes for the ECU to trigger DFCO. The upper limit for engine speed is the red line.

Once entered, DFCO remains on until you press the clutch in, resume throttle input, or let the engine drop below 1250 RPM. The automatic transmission will remain in DFCO during a downshift.

You can feel the car enter and exit DFCO and once it's triggered it can enter and exit DFCO every half second. The feel you get is a small reverse kick in the seat when entering DFCO and an equally small forward kick in the seat when exiting DFCO. We have had members complain about their Cruze "jerking" while descending long moderate hills on Cruze Control. This "jerking" is DFCO. You can also see DFCO in action on the DIC by putting the car in Metric and watching for 0 L/100KM.

I've posted it so many times I actually have it in a text file on my laptop. Copy/paste is great.

This is why I think I get better MPG with my automatic than most, when slowing down I ALWAYS downshift to keep the car above 1500RPM for a longer period on deceleration. Believe 1500RPM in 6th gear is 45mph, 5th gear 35mph, 4th gear 25mph.

If you leave the car in D, the RPM will be very low most of the time and only downshift when it needs to avoid stalling. Sure its still in DFCO allot of that time, but not as long as if you downshift.
