2003 Buick LeSabre Owner's Manual - Page 157

Safety Belt Reminder Light When the key is turned to RUN or START, a chime will come on for several seconds to remind people to fasten their safety belts. The safety belt light will also come on and stay on for several seconds, then flash for several more. Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows AIR BAG. The system checks the air bag's electrical system for malfunctions. The light tells you if there is an electrical problem. The system check includes the air bag sensors, the air bag modules, the wiring and the crash sensing and diagnostic module. For more information on the air bag system, see Air Bag Systems on page 1-52. This light will come on when you start your vehicle, and it will flash for a few seconds. Then the light should go out. This means the system is ready. If the driver's belt is already buckled, neither the chime nor the light will come on. AIR BAG If the air bag readiness light stays on after you start the vehicle or comes on when you are driving, your air bag system may not work properly. Have your vehicle serviced right away. 3-36
