1 Always use safety belts and the correct child restraint for your child's age and size. Even in vehicles equipped with a Passenger Sensing System, children are safer when properly secured in a rear seat in the appropriate infant, child or booster seat. Never place a rear-facing infant restraint in the front seat of any vehicle equipped with an active frontal air bag. Be sure every occupant is properly restrained. See the vehicle Owner's Manual and child safety seat instructions for more safety information.

5 OnStar services require vehicle 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 Communications 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 hardware, 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.
