Driving Hints BREAKING-IN Your vehicle does not need an extensive break-in. Try not to drive continuously at the same speed for the first 1000 miles (1600 kilometers) of new vehicle operation. Vary your speed frequently in order to give the moving parts a chance to break in. Do not add friction modifier compounds or special break-in oils since these additives may prevent piston ring seating. care if using automated commercial car washes. Do not drive through car washes with the vehicle heavily loaded (multiple passengers or luggage). Use only commercial car washes without mechanical tracks or hand wash to avoid potential damage. ENGINE OVERSPEED Note: Always wait until the engine is properly warmed up before running high engine speeds. Your ST vehicle is equipped with an overspeed feature to increase its performance range. The standard maximum engine speed of 6375 RPM is indicated by a narrow redline on the tachometer face. The redline becomes thicker at the overspeed engine speed of 6500 RPM. This feature allows three seconds of overspeed above 6375 RPM. Once the three second limit has been reached, the electronically controlled rev limit ramps down to 6375 RPM and holds there. Once engine speed has dropped below 6175 RPM, the overspeed timer is reset and three seconds of overspeed up to a maximum of 6500 RPM is enabled. Do not operate the engine at high RPM and low load for sustained periods of time, as damage may occur. GENERAL DRIVING POINTS Operating at High Speeds Your ST vehicle is capable of high speeds and is equipped with tires rated for the vehicle's maximum speed. Remember to drive safely, obey all traffic laws and only operate your ST vehicle at high speeds at locations equipped and designed to do so safely. Before operating your vehicle at high speeds: • • Verify correct tire pressures. See Tires (page 20). Inspect wheels and tires for wear and damage. Replace any damaged wheels or tires. Do not operate your vehicle at high speeds with more than two passengers or while carrying cargo. • Curbs, Parking Lot Obstacles and Commercial Car Washing As part of its performance tuning package, your ST vehicle has a lower ride height than a standard Fiesta. Because of lower ground clearance, use caution when approaching curbs, speed bumps or steep driveway ramps. It is recommended to cross speed bumps or driveway curbs slowly and at a 45 degree angle to reduce the risk of vehicle damage. Also, exercise extreme ENGINE OVERBOOST Your ST vehicle offers a period of additional torque delivery referred to as overboost or overtorque. This feature of the engine calibration broadens the RPM range of the peak torque curve. This gives improved performance during maneuvers such as passing and vehicle launch. 15 Fiesta (CCT)
