How OnStar Service Works
Automatic Crash Response, Emergency Services, Crisis Assist, Stolen Vehicle Assistance,
Vehicle Diagnostics, Remote Door Unlock, Roadside Assistance, Turn-by-Turn Navigation,
and Hands-Free Calling are available on most vehicles. Not all OnStar services are
available everywhere or on all vehicles. For more information, a full description
of OnStar services, system limitations, and OnStar terms and conditions, see www.onstar.com
(U.S.) or www.onstar.ca (Canada); contact OnStar at 1-888-4-ONSTAR (1&-888&-466&-7827)
or TTY 1&-877&-248&-2080; or push
to
speak with an Advisor. OnStar services require a vehicle electrical system, wireless
service, and GPS satellite technologies to be available and operating for features
to function properly. These systems may not operate if the battery is discharged
or disconnected.
OnStar service cannot work unless your vehicle is in a place where OnStar has an agreement with a wireless service provider for service in that area, and the wireless service provider has coverage, network capacity, reception, and technology compatible with OnStar’s service. Service involving location information about the vehicle cannot work unless GPS signals are available, unobstructed, and compatible with the OnStar hardware. OnStar service may not work if the OnStar equipment is not properly installed or it has not been properly maintained. If equipment or software is added, connected, or modified, OnStar service may not work. Other problems beyond OnStar’s control may prevent service such as hills, tall buildings, tunnels, weather, electrical system design and architecture of the vehicle, damage to the vehicle in a crash, or wireless phone network congestion or jamming.
