I just completed the 500 mile oil change in my new C7 GS. In manual mode there are shift lights at the top of the HUD. There is nothing in the manual about how to use them. What are they indicating and how are they used? Thanks for any help oh great guru's of the C7's. I love the car, by the way. It is an amazing step up from the C6. Still trying to learn all of the things it can do. https://www.corvetteforum.com/forums...lies/crazy.gif

I am on my 2nd C7 and my man I have to tell you I have not figured them out !! They seem to come and go when in the Track mode, never consistently on in a way that makes sense to me .....

Really? How hard is it to figure out? As you approach the red line the lights are intended to tell you it's a good time to shift now. Are you really haven't that much difficulty understand this simple concept? I got it the second I saw it.

slimjimp

Then tell us what you haave figured out. The lights do not come on in a succession, in a straight line, but are split. Appropriate any help.

Once your high enough in RPM's, and in the proper display, (track version of HUD) the light comes on at either end. Then they walk towards he middle. When the dots touch in the middle they change color and your at redline. I shift on the last dot before the touch happens or I bounce the limiter on track.

I already told you what I figured out - As you approach the red line the lights are intended to tell you it's a good time to shift now. I don't know what you mean by "do not come on in succession" in succession to what exactly? In a straight line? In Track mode there are lights that come from the left and right toward each other. Last time I checked that line was straight. And I don't know what you mean by "split". "Appropriate any help"? Really? I'm not sure that's even English. Perhaps you should try harder to explain what your problem seems to be then maybe I can explain. But in general the lights are telling you it's time to shift to the next gear. How hard is that to understand?

The HUD shift lights are functional in all modes in the M7, and I assume in manual mode on the A8. However, I do keep my HUD display in Track mode all the time, even when Tour or any other mode is selected on the console.

If you're not seeing them, you're not revving high enough.

Thanks for the help, gentlemen. I suspected that was how it worked but wanted to be sure. The manual offers no explanation.

I think this is pretty standard, they also change color as they appear, I think they go from blue to yellow to red.

I do not get the shift light in the round tach display or sport mode display. How are you getting the shift light in the sport display as I have tried with no success.

LT1 Z51

Shift lights are always in HUD. In the cluster you get a "halo effect" in Sport and Tour (where the RPM gage grows a yellow then it transitions to red). Shift lights are only in Track in the cluster.

Somebody ask Tadge why after all the hard work he puts in to develop this high tech car, the idiot suits @ GM can't understand how important it is to properly document them so that the consumers can UNDERSTAND WTF IS GOING ON ON THEIR $70K car.

By far the most abysmal, incomplete, hard to research, poorly organized and uninformative literature I have ever received with any car new or used. Which is harder to understand since it is by far the best car I have ever owned.

Just unfathomable. Maybe GM learned that from the Chinese.

i.e. the entity with which to be annoyed because an end user has to come to a friggin Internet forum to get information GM should have provided him would be GM, not the forum member trying to figure out what those mystery lights on the heads up are for. I figured they have something to do with telling me when to shift, but I won't use them unless I have documentation telling me what the benefit might be. I'll shift by tach and feel like I have for 40+ years. The real stupid part is they must of put these lights in as a driver aid, but then they left it for you to figure out what it's trying to tell you. You know, like Richard Dreyfus trying to decipher the light patterns on the side of the giant alien space pod in Close Encounters.

God help me it really doesn't get much more skull farked than that.

It's amazing, the condescension and hostility that can be generated by a simple question that's posed in a forum that's supposed to help people with answers to their questions, simply amazing.

BTW, in the post above I'm NOT referring to the criticism about the Corvette's owner manual - it's a joke. Kudos to those who provided help with the OP's initial question.

LT1 Z51

I think it's one of those, it seems intuitive so why does it need to be explained things.

People come here for help, but sometimes a dumb question gets critiqued. Complaining about that fact only belabors the point.

Owners manuals FWIW are bad because let's face it, most people do not read them. So why spend the time detailing every little thing?

We are in the age of, if you have to explain the UI then you've failed. Either the UI is bad (majority of people don't understand it) or the person just isn't a quick learner (or doesn't experiment with the UI, either way it's not the UI's fault).

I'm sure the technologically dense don't like hearing that, but it's true, and that's life.

The light (halo) doesn't show up in the Sport HUD, but the dots do on the Track HUD.

If you set your HUD to Track and your DIC to Sport you can see the relation between the the two, and the relation to optimal shift points and redline/rev limiter.

Foosh

As I originally said, I keep my HUD set to Track display, even though I may be in Tour, Sport, or other mode. I just prefer the Track display on the HUD. I change the HUD selector to Track mode every time I get in the car if I'm in some other mode.

Thus, I'm used to seeing the shift lights all the time, since that's what I'm always looking the Track display on the HUD. I was simply pointing out that you can be in any of the console-selected modes and still see the lights if your HUD is set to the Track display.

I agree it should be better explained in the manual.

I only saw condescension and hostility in poster #3 and his subsequent posts, but that's not unusual w/ him. It seems to me everyone else was trying to help.

mpuzach

I'm in 100% agreement with you on all counts. It was him and him alone who prompted my post.
