Warning Indicator Lights: Notes

Thunderbird SC is equipped with a shift indicator light and audible chime, warning driver of engine oil or coolant overheat while vehicle is operated at high speeds (above 100 MPH) for extended periods of time. The shift indicator light and chime will also warn driver when the engine has reached too high an RPM for that gear. The Powertrain Control Module (PCM) will reduce vehicle speed by limiting fuel to the engine when one of these overheat conditions has been reached. The driver may then notice a loss of power and/or a slight vibration. The shift indicator light will turn on and the audible chime will produce a steady tone to alert driver to upshift at this time. Full power will be restored and the shift indicator light and chimes will turn off when the vehicle returns to normal operating temperatures.
