Service Engine Soon; Speed Control (Rtt) - Ford Taurus 2015 Owner's Manual

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 Fuel and Refueling 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 Fuel and Refueling 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 have your vehicle serviced immediately by your
authorized dealer.
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. Have an authorized dealer service your vehicle
immediately.
Speed control (if equipped) (RTT)
The speed control system indicator light changes color to
indicate what mode the system is in:
• On (gray light-type 1, white light-type 2): Illuminates when the speed
control system is turned on. Turns off when the speed control system
is turned off.
• Engaged (white light-type 1, green light-type 2): Illuminates when the
speed control system is engaged. Turns off when the speed control
system is disengaged.
