ESP FORD FOCUS 2015 3.G ST Supplement Manual

Enhanced Torque VectoringControl
Enhanced torque vectoring control iscomprised of two elements:
•Torque vectoring control, which appliesbrake torque on the inner wheel in acurve for better traction and lessundersteer.
•Cornering understeer control whichcontrols the yaw response of thevehicle under braking and accelerationon high and low friction surfaces.
Unlike electronic stability control,enhanced torque vectoring control doesnot slow the vehicle. It helps controlexcessive wheel slip and gives the vehiclecornering agility. The system only increasesperformance. Because of this, the systemdoes not disable enhanced torquevectoring control when the AdvanceTrac®system is off.

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.

See the Wheels and Tires chapter of your owner's manual for instructions on changinga road wheel.
Your ST vehicle is equipped with a full-size, dissimilar spare tire assembly. Although thespare is a traditional, full size tire (as opposed to a mini-spare), it is different in both sizeand handling characteristics from the standard Focus ST performance tire. If you needto install the spare tire, you must adhere to the following precautions:
•Because of the different performance characteristics of the spare tire, avoid aggressivesteering, braking, acceleration or high speeds when you install the spare tire.
•Never enable electronic stability control sport mode or fully disable electronic stabilitycontrol when you install the spare tire.
•Replace the spare tire with the correct original equipment specified tire as soon aspossible.
The table lists the specifications for the full size spare tire and wheel assembly. Tire speedand load ratings should match those of the originally equipped tires as closely as possible.
