1 A NOTE ON CHILD SAFETY: Always use safety belts and proper child restraints, even in vehicles equipped with air bags. Even with the Passenger Sensing System, children are safer when properly secured in a real seat. Never place a rear-facing infant restraint in the front seat of any vehicle equipped with an active air bag. See you vehicle Owner's Manual and child safety seat instructions for safety information.
2 OnStar services require electrical system and analog wireless service to be available and operating for features to function properly. OnStar uses existing emergency service providers as well as analog wireless and satellite technologies and is subject to their limitations. The U.S. Federal Communication Commission (FCC) ruled that wireless carriers will no longer be required to support the analog wireless network after February 16, 2008. After that time, if the carriers for OnStar elect to only provide digital service, OnStar service will only be available through dual-mode software, which may require the purchase of a system upgrade. Call 1-888-4ONSTAR
(1-888-466-7827), see your OnStar Owner’s Guide, or visit onstar.com for system limitations and details.
