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.

•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.
