Completing the customer onboarding process is an important step that allows us to set-up your new vehicle account for the Owner Center and to activate and manage your OnStar Connected Services and Data subscription. This way, you will be able to access your vehicle-related accounts on both of our platforms: Owner Center and the myChevrolet, myGMC or myCadillac Mobile App*, using one single email address as your user ID. It also introduces you to many of your vehicle’s services. OnStar services, will not work until you have been onboarded and accepted terms & conditions and the privacy statement. Note: The statutory eCall emergency call function in UAE, for applicable vehicles, does not require you to onboard for OnStar services.
