Crash Response In a crash, a built-in sensor can automatically alert the On-Star advisor. An Advisor is immediately connected into your vehicle to determine if you are okay. If you're unable to respond, the Advisor can use GPS technology to pinpoint the location of your vehicle and send help, even if you can't ask for it.

Emergency Services You can push the emergency button at any time and connect immediately to an Advisor who can request emergency assistance to be dispatched to your location.

Crisis Assist During severe weather, natural disasters or other crisis, On-Star will provide a central point of contact to help you navigate away from dangerous conditions. Specially trained Crisis Advisors can help you reach loved ones, obtain food, water, medical supplies, find the closest evacuation route and address a wide range of other needs.

Good Samaritan If you witness a problem on the road, simply push the emergency button and report it. On-Star will relay the information to the proper authorities or send emergency help to that location.

Stolen Vehicle Tracking Assistance If you report your vehicle stolen to law enforcement, On-Star can use real-time GPS technology to pinpoint the exact location of the vehicle and will work with authorities to help recover it quickly. Roadside Assistance If you need a tow, tire change or fuel, one push of the On-Star button will immediately connect you to an Advisor who can help direct a service provider to your exact location.

Door Unlock (via Locksmith) The On-Star service includes the ability to call On-Star if you get locked out of your vehicle. The Advisor will dispatch a third-party to go to the vehicle and unlock it. However, this On-Star device cannot be used to remotely lock or unlock your doors.

Turn-by-Turn Navigation and eNav Enjoy built-in, available Turn-By-Turn Navigation, so you don't have to guess about how to get where you are going. The On-Star system will offer navigation services via voice-guided driving directions to practically any destination at the push of a button. You will be able to try a route at no additional cost by pushing your blue button or you can upgrade your service level for unlimited Turn-by-Turn Navigation. Also, eNav allows you to easily search for destinations using Google Maps or MapQuest and then send them directly to your vehicle.
