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.
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

Driving Hints
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.
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.
