2014 FORD FIESTA ESP

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.
No action is required to activate torquevectoring control. It operates automaticallydue to vehicle operating conditions.
Unlike electronic stability control,enhanced torque vectoring control doesnot slow the vehicle but does help controlexcessive wheel slip and gives the vehiclecornering agility. The system only increasesperformance. Because of this, enhancedtorque vectoring control is not disabledwhen the AdvanceTrac system is off.

WHEELS
Your ST vehicle is equipped with uniquewheels matched to the tires. These wheelsare more susceptible to damage due totheir diameter, width and low profile tires.To avoid damage to your wheels:
•Maintain proper tire pressure.
•Exercise caution when usingautomated, commercial car washes.Hand washing or using touchlesscommercial car washes withoutmechanical tracks is the best way toavoid potential damage.
•When installing wheels, always torquelug nuts to specification with a torquewrench.
•Inspect your wheels for damage on aregular basis. If a wheel is damaged,replace it immediately.
•If you encounter an abnormally harshimpact, inspect the outer diameter ofyour wheels, both inside and out, fordamage.
TIRES
Your ST vehicle is equipped with lowprofile, high performance tires that aredesigned to optimize the driving dynamicsyou expect in an ST vehicle. These tires arenot optimized for off-road or winter (snowor cold weather) performance, and theirride, noise and wear characteristics aredifferent than non-performance tires. Also,
because of their lower profile, the tires aremore susceptible to damage due topotholes and rough roads. To make surethat your tires perform as intended, it isimportant that you maintain your tiresproperly:
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.

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 speed
rating less than the original equipment tires(to fit snow chains, for example), be awareof the maximum speed rating for the tireand never exceed.

CHANGING A ROAD WHEEL
See the Wheels and Tires chapter of yourowner's manual for instructions onchanging a road wheel.
Full Size Spare
Your ST vehicle is equipped with a full size,dissimilar spare tire assembly. Althoughthe spare is a traditional, full size tire (asopposed to a mini spare), it is different inboth size and handling characteristics fromthe standard Fiesta ST performance tire.If you need to install the spare tire, youmust adhere to the following precautions:
•Because of the different performancecharacteristics of the spare tire, avoidaggressive steering, braking,acceleration or high speeds when thespare tire is installed.
•Never enable electronic stabilitycontrol sport mode or fully disableelectronic stability control when thespare tire is installed.
•Replace the spare tire with the correctoriginal equipment specified tire assoon as possible.
The following table lists the specificationsfor the full size spare tire and wheelassembly. Tire speed and load ratingsshould match those of the originallyequipped tires as closely as possible.

Wheel Lug Nut TorqueSpecifications
WARNING
When a wheel is installed, alwaysremove any corrosion, dirt or foreignmaterials present on the mountingsurfaces of the wheel or the surface of thewheel hub, brake drum or brake disc thatcontacts the wheel. Make sure that anyfasteners that attach the rotor to the hubare secured so they do not interfere withthe mounting surfaces of the wheel.Installing wheels without correctmetal-to-metal contact at the wheelmounting surfaces can cause the wheelnuts to loosen and the wheel to come offwhile the vehicle is in motion, resulting inloss of control.
Retighten the lug nuts to the specifiedtorque at 500 miles (800 kilometers) afterany wheel disturbance (such as tirerotation, changing a flat tire, wheelremoval).
