CAUTIONTo help avoid personal injury from unrepaired crash damage to a restraint system, perform the seat belt check for each seat belt system. Replace the seat belt system if there is any doubt about the condition of system components.
  1. The front seat belt system consists of a driver and passenger seat belt retractor and buckle.

When the driver seat belt is buckled with the LF door closed and the ignition switch in the ON position, the following events occur: The audio alarm will not operate. The seat belt indicator will not operate.
  3. When the driver seat belt is not buckled with the LF door closed and the ignition switch in the RUN position, the following events will occur: The audio alarm will operate for 4-8 seconds and then turn OFF. The seat belt indicator will operate for 20 seconds or until the driver seat belt is buckled. The seat belt indicator will flash for an additional 55 seconds before turning OFF.
