See Figures 1 and 2

The Service Reminder Indicator (SRI) lamp is used with 5.9L V8 heavy duty and 8.0L gas powered engines only. It is not used with diesel engines. The lamp is found on the instrument panel and reads "MAINT REQ'D.''

The SRI system is a part of the engine controller computer. It records vehicle mileage and stores it in memory. The engine controller checks for certain mileage intervals. When they are reached, the SRI lamp is illuminated on the instrument panel.
