ENGINE OVERSPEED
Note:Always wait until the engine isproperly warmed up before running highengine speeds.
Your vehicle has an over-rev feature toincrease the performance range of yourFocus ST. The standard maximum enginespeed of 6500 RPM is indicated by anarrow red line on the tachometer face.The red line becomes thicker at theover-rev engine speed of 6800 RPM.
This feature allows three seconds ofover-rev above 6500 RPM. Once the threesecond limit has been reached, theelectronically controlled rev limit rampsdown to 6500 RPM and holds there. Oncethe engine speed has dropped below 6300RPM, the over-rev timer is reset and threeseconds of over-rev up to a maximum of6800 RPM is enabled.
Do not operate the engine at high RPM andlow load for sustained periods of time, asdamage may occur.
ENGINE OVERBOOST
Your ST vehicle offers a period ofadditional torque delivery referred to asoverboost or overtorque. This feature ofthe engine calibration broadens the RPMrange of the peak torque curve. This givesimproved performance during maneuverssuch as passing and vehicle launch.
Note:The overboost feature controls avariety of engine parameters to deliveradditional torque. Overboost is built into theengine calibration on your ST vehicle andno action is required by the driver to engage.
