2015 FORD FOCUS 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.

ROADSIDE ASSISTANCE
Contact your roadside assistance centeror a professional towing service if you needto have your vehicle towed.
Ford recommends that your vehicle betowed with a wheel lift and dollies or withflatbed equipment. When towing with aflatbed, 4x4 blocks may help preventdamage when loading or unloading yourvehicle. Do not tow with a slingbelt. FordMotor Company has not approved aslingbelt towing procedure.
Note:If the vehicle is towed by other meansor incorrectly, vehicle damage may occur.

As standard, your ST vehicle is equippedwith low profile, high performance tiresthat are designed to optimize the drivingdynamics you expect in a ST vehicle. Thesetires are not optimized for off-road orwinter (snow or cold weather)performance, and the ride, noise and wearcharacteristics are different thannon-performance tires. Also, because oftheir lower profile, the tires are moresusceptible to damage due to potholesand rough roads. To make sure that yourtires perform as intended, it is importantthat you maintain your tires properly:
Note:Do not use tire chains on the originalwheels and tires of your vehicle. The use ofany type of tire chain on these tires maydamage your vehicle.
•Do not overload your vehicle. Maximumvehicle and axle weights are listed onthe tire information placard.
•Take extra caution when operating thevehicle near its maximum load,including assuring proper tire pressureand reducing speeds.
•Take extra caution when operating onrough roads to avoid impacts thatcould cause tire damage.
•If you encounter an abnormally harshimpact, inspect your tires for damage.
•Inspect your tires for damage on aregular basis. If a tire is damaged,replace it immediately.
•Proper suspension alignment is criticalfor maximum performance andoptimal tire wear. If you notice uneventire wear, have your alignment checked.
•When replacing tires, the only way tomaintain original performance is to usethe original equipment tire. If a differentsummer tire is used, it should be thesame size, speed rating and load ratingas the originally equipped tire. Replacetires as a set of four. Never mix tirebrands or models.
Tire Pressure
Note:You may need to remove the sparewheel from the spare wheel well to checkthe tire pressure.
•For tire pressures, see the placardlocated on the B-pillar inside thedriver's door.
•Always maintain your tire pressuresaccording to the tire informationplacard on the driver's door jamb, usingan accurate gauge.
19Focus (CDH), enUSA, First PrintingWheels and Tires

•Tire pressures are specified cold. Checkthem after the vehicle has been parkedfor at least three hours. Do not reducepressure of warm tires.
•Check your tire pressure often tomaintain it properly. Tire pressure candiminish over time and fluctuate withtemperature.
Optional All-Season Tires
Your Focus ST may come equipped withan optional All-Season performance tire.This choice will provide the benefit of fourseason mobility without requiring theinstallation of winter tires. It is importantto realize that ultimate summerperformance will be reduced relative tothe standard equipment summer only tire.Additionally, ultimate winter traction andcontrol will be less than a dedicated wintertire would provide. If you drive during thewinter months in areas with heavy snowfalland/or hilly terrain, you may wish to installa dedicated winter tire if ultimate tractionand control is desired.
USING WINTER TIRES
The standard equipment tires on your STvehicle are designed for maximumperformance in dry and wet summerconditions. They are not designed forwinter use on ice or snow and you cannotuse them with snow chains. Ford does notrecommend using the original equipmenttires when temperatures drop toapproximately 41°F (5°C) or below(depending on tire wear and environmentalconditions) or in snow and ice conditions.You must use winter or all-season tires ifyou will be operating your vehicle in theseconditions.
•Even with clear, dry driving conditionsdo not operate your vehicle aboveposted speed limits or perform highspeed maneuvers with winter tires.
•Do not use tire chains on the originalwheels and tires of your vehicle. Theuse of any type of tire chain on thesetires may damage your vehicle.
The following table lists acceptable tiresizes for winter tires. Tire speed and loadratings should match those of the originallyequipped tires as closely as possible. If itis required to fit winter tires with a speedrating less than the original equipment tires(to fit snow chains, for example), be awareof the maximum speed rating for the tireand never exceed.

Your ST vehicle is equipped with unique wheels matched to the tires. These wheels aremore susceptible to damage due to their diameter, width and low profile tires. To avoiddamage to your wheels:
•Maintain proper tire pressure.
•Exercise caution when using automated, commercial car washes. Hand washing orusing touchless commercial car washes without mechanical tracks is the best wayto avoid potential damage.
•When installing wheels, always torque lug nuts to specification with a torque wrench.
•Inspect your wheels for damage on a regular basis. If a wheel is damaged, replace itimmediately.
•If you encounter an abnormally harsh impact, inspect the outer diameter of yourwheels, both inside and out, for damage.
