STANDARD DRIVER INFORMATION CENTER (DIC) ========================================

THE 1997-98 GRAND PRIX FEATURES A "CHANGE OIL SOON" LIGHT IN THE DRIVER INFORMATION CENTER (DIC). THIS LIGHT WILL COME ON, BASED ON SEVERAL INPUTS, TO ALERT THE DRIVER THAT THE OIL SHOULD BE CHANGED.

THE RESET PROCEDURE IS: WITH THE IGNITION KEY IN THE "ON" POSITION, BUT THE ENGINE OFF, FULLY PUSH AND RELEASE THE ACCELERATOR PEDAL SLOWLY 3 TIMES WITHIN 5 SECONDS. IF THE "CHANGE OIL" LIGHT FLASHES, THE SYSTEM IS RESETTING. TURN THE KEY OFF, THEN START THE VEHICLE. IF THE "CHANGE OIL" LIGHT COMES BACK ON, THE LIGHT HAS NOT RESET. REPEAT THE PROCEDURE.

IT IS NECESSARY TO PRESS THE PEDAL ALL THE WAY TO THE FLOOR. IN SOME CASES, IT MAY BE NECESSARY TO MANUALLY OPERATE THE THROTTLE LINKAGE UNDER THE HOOD TO GET ENOUGH THROTTLE OPENING TO MAKE THE LIGHT RESET. IF THE SYSTEM WILL STILL NOT RESET, CALL TECHNICAL ASSISTANCE FOR A PROCEDURE TO RESET THE LIGHT USING THE TECH 2.
