The active cruise control does not appear to be able to be completely turned off, you can only cancel a particular speed you have set. I have experienced multiple times in a parking lot situation when trying to park that as steering wheel was spinning, it is very easy to hit the toggle switch that sets/resumes the cruise control, at that point vehicle may acclerate to the set point as you are trying to park. You must quickly either hit the cancel button or the brake to disengage the cruise control that you have no intention of engaging. Although I have been able to get the situation under control, had another moving car or pedestrian been close by, not sure if I would have same result. I have gone through the operating manual provided with the vehicle, and from what I can tell, there is nothing in the manual that even tells you how to operate the active cruise control. It seems like there needs a aœsystem off switcha so the set/resume button is not active, until the system is turned on. I have owned many GMC Products, and none have had the design where the toggle switch sticks out from the steering wheel and is easily inadvertently engaged. Usually the controls are flat/smooth like the aœcancela button on this vehicleaa.which canat easily be engaged accidentally. Luckly, I have not had a crash or injured a pedestrian
