How OnStar® Service WorksIn order to provide you with OnStar® services,your vehicle’s OnStar® system has the capabilityof recording and transmitting vehicle information.This information is automatically sent to anOnStar® Call Center at the time of an OnStar®button press, Emergency button press or ifyour airbags or AACN system deploys. The vehicleinformation usually includes your GPS locationand, in the event of a crash, additional informationregarding the accident that your vehicle hasbeen involved in (e.g. the direction from whichyour vehicle was hit). When you use the VirtualAdvisor feature of OnStar® Hands-Free Calling,your vehicle also sends OnStar® your GPSlocation so that we can provide you withlocation-based services.OnStar® service cannot work unless your vehicleis in a place where OnStar® has an agreementwith a wireless service provider for service in thatarea. OnStar® service also cannot work unlessyou are in a place where the wireless serviceprovider OnStar® has hired for that areahas coverage, network capacity and receptionwhen the service is needed, and technology thatis compatible with the OnStar® service. Not allservices are available everywhere, particularly inremote or enclosed areas, or at all times.OnStar® service that involves location informationabout your vehicle cannot work unless GPSsatellite signals are unobstructed and available inthat place as well.Your vehicle must have a working electricalsystem (including adequate battery power) for theOnStar® equipment to operate. There are otherproblems OnStar® cannot control that may preventOnStar® from providing OnStar® service to youat any particular time or place. Some examples aredamage to important parts of your vehicle in anaccident, hills, tall buildings, tunnels, weatheror wireless phone network congestion.Your ResponsibilityYou may need to increase the volume of your radioto hear the OnStar® advisor.
