* OnStar services require vehicle electrical system (including battery), wireless service and GPS satellite signals to be available and operating for features to function properly. OnStar acts as a link to existing emergency service providers. Subscription Service Agreement required. The U.S. Federal Communications Commission (FCC) ruled that wireless carriers will no longer be required to support the analog wireless network beginning in 2008. As of January 1, 2008, OnStar plans to offer service only through equipment that operates on the digital network which may require the purchase of a system upgrade for eligible vehicles.
