FORD 2011 Edge v.1 - Manual (Page 13)

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 message center and function the same as
a warning light but does not display on startup.
Service engine soon: The service
engine soon indicator light
illuminates when the ignition is first
turned on 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 AWD fault has
been detected. Contact your
authorized dealer as soon as possible.
