As of 2015, every new Cadillac comes with a free one-year subscription to the OnStar Directions and Connections plan. After the free subscription expires, Cadillac owners have the option to purchase additional coverage.
The lowest tier of OnStar service includes automatic crash response, roadside assistance and a mobile app. Additional tiers of service include features such as alarm notification, stolen vehicle assistance, navigation and hands-free calling minutes. Discounts are available when paying for a year's subscription in advance.
Owners of Cadillacs and other GM vehicles that have 4G LTE capability can purchase data plans that enable use of the vehicle as a Wi-Fi hot spot.
