FORD 2013 Focus v.2 - Manual (Page 106)

Parking Lamps
It will illuminate when you switch the parking lamps on.
Service Engine Soon
If the service engine soon indicator light stays illuminated after
the engine is started, it indicates that the On Board Diagnostics
system (OBD) has detected a malfunction of the vehicle
emissions control system. Refer to On board diagnostics (OBD) in the
Fuel and Refueling chapter for more information about having your
vehicle serviced.
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.
Note: Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter or other vehicle components.
The service engine soon indicator light illuminates when the ignition is
first turned on prior to engine start 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 Readiness for
Inspection/Maintenance (I/M) testing in the Fuel and Refueling
chapter.
Stability Control System
It will flash when the system is active. It will illuminate when
you switch the ignition on to confirm it is functional. If it
remains illuminated or does not illuminate when you switch the
ignition on, this indicates a malfunction. During a malfunction the system
will switch off. Have the system checked by your authorized dealer.
Stability Control System Off
It will illuminate when you switch off the system. It will go out
when you switch the system back on or when you switch the
ignition off.
