The eco auto programming is indeed different from the rest.

I tend to leave (put) mine in M5 since I often find myself in a 40 to 45 speed zone.
The trans is programmed for [email protected] 42 mph......so, if I drive in auto, it drops back to fifth every time I drop back to 40.....then, of course, as speed increases to 42+, it upshifts........back and forth, back and forth.....so I leave it in M5.

Starting from a light, it is in first but displays M5......it will only shift up as far as fifth......I have found this improves my 'light throttle' mileage a bit as well.

Also note, the eco does not ever display a 'upshift denied' on the D.I.C.


I've a question for the non eco members.......Do you folks have the option of a second gear start?.......the eco does not.....it will start off in first regardless of position displayed.

I wish I could have it both ways, a auto/manual mode like yours where i could lock out upper overdrive gears and other times full manual mode like my RS auto. With my auto its nice to be able to get on the throttle and not cause a downshift, having this control does gain MPG(keeping the RPMs lower).



This is exactly how most other GM cars behave and I was shocked my cruze was so different.



I can start out in 2nd or even 3rd(I would not recommended starting in 3rd I feel this is a programming bug). Its definitely in those gears, you can feel a slight clunk and more vibration once moving to 2nd and even more again in 3rd.
I sometimes wish it was both ways as well......a second gear start is nice to have on slick, winter streets.......not the end of the world, just a bit more control.

I am fond of the ability to leave it in M5 though and I think it upshifts just a touch sooner.

Thanks for responding......one of those questions I've been wanting to ask for, like, three years.

Thanks, good to know my car isn't messed up.

So are you saying only the overdrive gear can be "locked out"?
Because obviously, my car will upshift once it detects im off the throttle slightly or gets close to redline.

It was just really weird and honestly a little disappointing when I first used the manual mode.
Leaving it in M6 and basically having it behave like full auto without even displaying the gear changes .. is a drastic difference from my G37, which holds gears bouncing on the rev limiter all day and rev matches on downshifts.
Depending on what you selected, ie, M1,M2,M3,M4,M5,M6, the car will start out in first and advance only to the gear selected.

For example, if M3 is selected it will shift, first, second, third, and hold third regardless of speed up to RPM cutoff.
