Instrument Cluster Many lights will illuminate when you start your vehicle to make sure the indicators work. If any light remains on after starting the vehicle, refer to the respective system warning light for additional information. Note: Some warning lights are reconfigurable telltale (RTT) indicators. These indicators display in the lower line of the message center near the odometer reading. They function the same as a warning light but do not display on startup. 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. 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/reduced power (RTT): Illuminates when a powertrain or an 4WD fault has been detected. Contact your authorized dealer as soon as possible. 13 2012 Explorer (exp) Owners Guide, 2nd Printing USA (fus)
