To disable your auto stop/start feature on your 2020
GMC Sierra, you need to press the auto start/stop button, which looks like a capital A with a revolving circle around it.
To turn auto stop/start back on, press the button again. The auto start/stop disable switch should be found on a button just below the front climate controls.
After you completely shut off your vehicle, the feature will automatically turn back on the next time you start it.
Hope this helps! As you continue looking after your 2020 GMC Sierra, make sure it’s protected by the right
car insurance policy.
