1. Head curtain side air bags are designed to help reduce the risk of head and neck injuries to front and rear seat occupants on the near side of certain side-impact collisions.
Always use safety belts and the correct child restraints for your child’s age and size, even in vehicles equipped with air bags. Children are safer when properly secured in a rear
seat. See your vehicle Owner’s Manual and child safety seat instructions for more information.
5. Gross Vehicle Weight Rating (GVWR). When properly equipped, includes vehicle, passengers, cargo and equipment.
