Downloading and installing vehicle software updates can be done via the vehicle’s available built-in data connection or a Wi-Fi® connection.* A paid data plan is not required. To be eligible for vehicle software updates for your vehicle, you must have accepted the connected vehicle User Terms for Connected Vehicle Services and OnStar® Privacy Statement for the vehicle.
Important: During vehicle software update installation, the vehicle is disabled and cannot be driven. There is no option to cancel or override the installation once started. Therefore, customers are presented with the option to “Download/Install” or wait for a more convenient time using the “Remind Me Later” or “Schedule” (if available) options; or they can exit the vehicle (the update will be offered on next ignition cycle for up to 30 times). If they select “Download/Install,” the customer will be asked for acceptance twice — both the estimated time for installation and a statement that the vehicle will be immobilized for the time of installation — on the vehicle’s touch-screen.
Here’s how the vehicle software updates work:
- Notices of updates can be sent to your vehicle or you can manually check for updates via the center screen
- When an update is made available for your vehicle, you will receive an in-vehicle notice upon your next ignition cycle or the next time your vehicle is placed into PARK
There are two steps to the process: software download and software installation. The specific steps required to download or install may vary by vehicle:
- Download/Install: You can choose from the below options for the download and installation processes:
- Download: You can continue to use your vehicle normally. After the download is complete, you will be prompted to accept installation upon placing the vehicle in PARK or on your next ignition cycle
- Install: Choose “Install Now” or wait for a more convenient time using the “Remind Me Later” option. Once installation has begun, the vehicle will be disabled and cannot be driven. You may turn the vehicle off and exit the vehicle.
- Remind Me Later: This selection gives you the option of being prompted about the update at a later time
- Dismiss/Next Time: If you choose this option, you will be prompted about the update after your next ignition cycle. The number of times you can dismiss an update notice may vary
- Schedule (2021 vehicles and newer): If you choose this option, you will select the time that you’d like the update to install
- Decline/Delete: If you choose this option, you will not be reminded again and the update will not occur. Instead, you can take your vehicle to your dealer to perform the update at a later time
