BREAKING-IN
Your vehicle does not need an extensivebreak–in. Try not to drive continuously atthe same speed for the first 1000 miles(1600 kilometers) of new vehicleoperation. Vary your speed frequently inorder to give the moving parts a chance tobreak in.
Do not add friction modifier compoundsor special break–in oils since theseadditives may prevent piston ring seating.
GENERAL DRIVING POINTS
Operating at High Speeds
Your ST vehicle is capable of high speedsand is equipped with tires rated for thevehicle’s maximum speed. Remember todrive safely, obey all traffic laws and onlyoperate your ST vehicle at high speeds atlocations equipped and designed to do sosafely. Before operating your vehicle athigh speeds:
•Verify correct tire pressures. See Tires(page 20).
•Inspect wheels and tires for wear anddamage. Replace any damaged wheelsor tires.
•Do not operate your vehicle at highspeeds with more than two passengersor while carrying cargo.
Curbs, Parking Lot Obstacles andCommercial Car Washing
As part of its performance tuning package,your ST vehicle has a lower ride height thana standard Fiesta. Because of lower groundclearance, use caution when approachingcurbs, speed bumps or steep drivewayramps. It is recommended to cross speedbumps or driveway curbs slowly and at a45 degree angle to reduce the risk ofvehicle damage. Also, exercise extreme
care if using automated commercial carwashes. Do not drive through car washeswith the vehicle heavily loaded (multiplepassengers or luggage). Use onlycommercial car washes withoutmechanical tracks or hand wash to avoidpotential damage.
ENGINE OVERSPEED
Note:Always wait until the engine isproperly warmed up before running highengine speeds.
Your ST vehicle is equipped with anoverspeed feature to increase itsperformance range. The standardmaximum engine speed of 6375 RPM isindicated by a narrow redline on thetachometer face. The redline becomesthicker at the overspeed engine speed of6500 RPM.
This feature allows three seconds ofoverspeed above 6375 RPM. Once thethree second limit has been reached, theelectronically controlled rev limit rampsdown to 6375 RPM and holds there. Onceengine speed has dropped below 6175RPM, the overspeed timer is reset andthree seconds of overspeed up to amaximum of 6500 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.
