Instrument Cluster Service engine soon: The service engine soon indicator light illuminates when the ignition is first turned to the on position to check the bulb and to indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing. Normally, the service engine soon light will stay on until the engine is cranked, then turn itself off if no malfunctions are present. However, if after 15 seconds the service engine soon light blinks eight times, it means that the vehicle is not ready for I/M testing. See the Readiness for Inspection/Maintenance (I/M) testing in the Maintenance and Specifications chapter. Solid illumination after the engine is started indicates the On Board Diagnostics System (OBD-II) has detected a malfunction. Refer to On board diagnostics (OBD-II) in the Maintenance and Specifications chapter. If the light is blinking, engine misfire is occurring which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration) and contact your authorized dealer as soon as possible. If the light remains on while driving, the temperature of the engine may be too high; refer to Engine coolant in the Maintenance and Specifications chapter. WARNING: Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior floor coverings or other vehicle components, possibly causing a fire. Powertrain malfunction indicator: Illuminates when a powertrain, a 4x4 or an AWD fault has been detected. Contact your authorized dealer as soon as possible. • Standard instrument cluster • Optional instrument cluster 13 2010 07+ Explorer Sport Trac (esp) Owners Guide (own2002), 1st Printing USA (fus)
