Does anyone with the AT use the driver shift control (DSC) feature? What is the advantage of using it? Manual transmission cruzes seem to avg better mpg so would using the DSC allow one to get better mileage out of the AT? If not that, when would one use this feature? Also any tips on how to use it, when do you shift etc?

I use the manual mode frequently (1.4 A/T) if I find myself driving <40 mph. I manually take off from a stop in 2nd gear. (Yes, while stopped, manually shift up to 2nd gear, the DIC will show 2nd gear.) Now, the car will always take off in 2nd gear as long as you stay in the manual mode. This really helps in getting control of the zippy rpm's on initial take off. Next, don't be in a hurry.....easy on the gas....the car will accelerate from a stop in 2nd gear quite well. Now, the goal is to control the zippy rpm's so you need to upshift ASAP...3rd gear as soon as you're off and rolling...4th around 20 or so (if you shift too early...no problem, the computer "Denies the shift" until you're rolling abit faster), 5th around 25 mph and 6th at 35 mph. You'll get use to the shift points pretty quick.

Why does this work?....because if you are driving <40 mph in the Auto mode...you'll be in 5th gear until over 40!! Remember, you can't be in a big hurry doing this as you'll be lugging the engine and negating the purpose of better mpg.

I recommend once you are back to 40> mph, shift back over to the AUTO mode. The reason for going back to the auto mode is so you downshift when you need power and you don't forget you're in the manual mode miles later down the road. I have, more than once, found myself driving in 2nd gear doing 4000 rpm's....oops!! These Cuzes's are just too darn quiet!!:D We are very satisfied with our LTZ RS, now with 12,706...no problems.:) With a little practice using the manual mode will become second nature and it does have a positive influence on the overall mpg, when done correctly.

PS. Our "Lifetime" mpg is currently 31 mpg. Lately averaging around 35 mpg. Love it!

you can also start out in third.
Not in an auto you can't. You can't shift into third until at least 10 mph. I think 4th is 17 or 18, 5th is about 22 and 6th is 30. These are all the earliest the car will let you shift into them - not saying you should.


I myself often skip first unless I'm on an incline or need a quicker start (not often). Actually often times in heavy traffic I will shift pretty early since people take time to get going from a stop in heavy traffic.

If I am at a complete stop and shift twice it says I am in third. Tried to go to fourth but said shift denied. - just saying

I do the same as jaygeo1. It is also a bit smoother start from a stand still. Then I'll shift back to auto once on the go. I don't do it all the time, just once in a while and mainly in traffic.

That's a good post Jaygeo1. I've found that all shifts can be accomplished at about 2K RPM. That seems a bit easier than watching for certain speeds. The average MPG improves dramatically, whereas shifts at 3K or higher are costly.

I started following that for the shifting around town, and works a treat. helps a lot.

Yeah i got some videos on my facebook page if you have a facebook. My name is Matthew Busch-Lobberecht. I got a 2012 cruze LT. My profile pic should be of me standing by my cruze. Its a blue topaz metallic color. My cover photo is of chevrolet. Feel free to check those out and i hope those help you. By the way, what i say when to shift is the right time and right way to do it bec if you do it too late you hurt ur mpg and could possibly hurt the engine and tranny =]. Any q's dont hesitate to ask. Thanks

Nice to meet you, seems pretty random to post on this 1.5year old thread with nothing relevant to the conversation.

I'll add something: The 2012 can still take off in 2nd gear for improved snow traction.

Hey Matthew this is Chris from facebook, the person who told you to join. What do you think of the forum so far?

Hi guys,

Is there a way to invert the Driver Shift Control (DSC), I mean shifting down should increase the gears, and shifting up should decrease the gears and not the other way around.

I'm tempted to do the re-wiring myself.

I've heard that a few times though I see that logic as backwards. You press up(forward) to up shift, and pull down(backward) to downshift. Seems very straight forward and correct to me.
