After pushing the button once without brake the annoying DIC message appears.

But if I then wait for a count of 12 (say 10 seconds) doing nothing all of a sudden ACC mode clicks in and infotainment lights up.

Would be good if the manual mentioned the 10 sec delay, but now you know.

Press Engine Start/Stop button without pressing the brake.

You can also hold it(start/stop) in for 6 seconds with out the brake and it brings everything to life and you can review PDR etc.

Funny how it's not actually in the manual (unless I missed it), but it does say that it goes into acc when you turn the C8 off.

I think an on/off toggle would be way cooler. Or 3 way on off acc or 3 way push button with led lights.

Then again a key would be cool too.

From the manual, page 165:

ACC/ACCESSORY (Amber Indicator Light) :
This mode allows the use of some electrical accessories when the engine is off. With the ignition off, pressing the button one time without the brake pedal applied will place the ignition in ACC/ACCESSORY. The ignition will switch from ACC/ACCESSORY to off after five minutes to prevent battery rundown.

Service Mode
This power mode is available for service and diagnostics, and to verify the proper operation of the malfunction indicator lamp as may be required for emission inspection purposes. With the vehicle off and the brake pedal not applied, pressing and holding ENGINE START/STOP for more than five seconds will place the vehicle in Service Mode. The instruments and audio systems will operate as they do in ON/RUN, but the vehicle will not be able to be driven. The engine will not start in Service Mode. Press ENGINE START/STOP again to turn the vehicle off.



Nothing about the 10 second delay for accessory mode to power up the infotainment system. 10 seconds is a long time when you expect something to happen immediately, I would figure it wasn’t really going into ACC mode. Thanks @C8J for the heads up.

Thanks for the post. I've learned that whoever wrote the manual and index uses a different vocabulary than me. Without turning/reading every page in the manual, it is almost impossible to find what you are looking most of the time from the index.

FYI, all the pages in the manual are off by 1 in Adobe. It counts the cover as page 1.

I guess it was a silly question because everyone owns a Chevy. Maybe their only previous or current car is a Porsche
