Safety Belt Reminder Light When the key is turned to ON 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. If the driver's belt is already buckled, neither the chime nor the light will come on. 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 air bag readiness light stays on after you start the vehicle or comes on when you are driving, your air bag system or safety belt pretensioners may not work properly. Have your vehicle serviced right away. {CAUTION: Air Bag Readiness Light There is an air bag readiness light on the instrument panel, which shows the air bag symbol. 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 sensor, the air bag modules, the wiring, diagnostic module, and safety belt pretensioners. For more information on the air bag system, see Air Bag Systems on page 1-72. For more information on safety belt pretensioners, see Safety Belt Pretensioners on page 1-46. If the air bag readiness light stays on after you start your vehicle, it means the air bag system may not be working properly. The air bags in your vehicle may not inflate in a crash, or they could even inflate without a crash. To help avoid injury to yourself or others, have your vehicle serviced right away if the air bag readiness light stays on after you start your vehicle. 3-43
