Procedure notes
Is the clock in your 2021 GMC Sierra 3500 HD slow or fast? Learn how to toggle through the correct menu items to set the time correctly in your GMC. You will see whether your GMC needs to be turned on and how to navigate to the clock settings and accurately set the time in this free how-to video for a 2021 GMC Sierra 3500 HD.
In some vehicles, you must use the buttons on the steering wheel to toggle through menus in the dashboard, where the speedometer is, to adjust the time. When you change the time this way, the other clocks on top of the dashboard and on the radio display will update automatically too. Some vehicles with analog clocks adjust the time in the analog clock separately from the clock in the radio. Many newer vehicles make it so you cannot change the time unless you deselect the automatic time option in the entertainment system.
