MANUAL 6-SPEED TRANSMISSION OPERATION
Using the Clutch
Note:During each shift, the clutch pedal must be fully pressed to the
floor and the accelerator fully released. Failure to follow this may cause
increased shift efforts, prematurely wear transmission components, or
cause gear clash or damage to the transmission. Make sure the floor mat
is properly positioned so it doesn’t interfere with the full extension of the
clutch pedal.
Note:If you attempt to shift when the drive wheels are spinning with a
loss of traction, it is possible to cause damage to the transmission. Do
not attempt to shift when the drive wheels do not have traction.
Note:Do not drive with your foot resting on the clutch pedal or use the
clutch pedal to hold your vehicle at a standstill while waiting on a hill.
These actions will reduce the life of the clutch.
Your vehicle is equipped with a twin disc clutch. Due to the high
performance of the powertrain, a certain amount of noise from the
transmission is normal.
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully pressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the transmission selector
lever in positionN.
3. Start the engine, then press the brake pedal and release the parking
brake.

4. Move the transmission selector lever to position1, then slowly release
the clutch pedal while slowly pressing on the accelerator.
5. To engage reverse, lift up on the reverse lockout ring located under
the shift knob and move the transmission selector lever fully to the left
and forward.
Recommended Shift Speeds for Maximum Fuel Economy
When accelerating, upshift according to the following chart:
Upshifts when accelerating*
Shift from:
1 - 2 12 mph (19 km/h)
2 - 3 23 mph (37 km/h)
3 - 4 32 mph (51 km/h)

5 - 6 42 mph (67 km/h)
*pending EPA fuel economy certification
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 (seeTiresin this supplement).
•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.

ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
The AdvanceTracsystem includes traction control (TCS) and electronic
stability control (ESC). See theTraction ControlandStability Control
chapters of theOwner’s Manualfor more information
AdvanceTracprovides three modes
of operation specially calibrated for
the Focus ST. These are controlled
through the AdvanceTracbutton
on the center console.

ENHANCED TORQUE VECTORING CONTROL
Enhanced torque vectoring control (eTVC) is comprised of two elements:
•Torque vectoring control which applies brake torque on the inner
wheel in a curve for better traction and less understeer
•Cornering understeer control which controls the yaw response of the
vehicle under braking and acceleration on high and low friction
surfaces.
Unlike ESC, eTVC control does not slow the vehicle but does help
control excessive wheel slip and gives the vehicle cornering agility. The
system only increases performance. Because of this, eTVC is not disabled
when the AdvanceTracsystem is off.
ENGINE OVER-REV
Note:Always wait until the engine is properly warmed up before
running high engine speeds.
Your vehicle is equipped with an over-rev feature to increase the
performance range of your Focus ST. The standard maximum engine
speed of 6500 rpm is indicated by a narrow redline on the tachometer
face. The redline becomes thicker at the over-rev engine speed of
6800 rpm.
This feature allows three seconds of over-rev above 6500 rpm. Once the
three second limit has been reached, the electronically controlled rev
limit ramps down to 6500 rpm and holds there. Once engine speed has
dropped below 6300 rpm, the over-rev timer is reset and three seconds
of over-rev up to a maximum of 6800 rpm is enabled.
Do not operate the engine at high rpm and low load for sustained
periods of time, as damage may occur.
OVERBOOST
The Focus ST 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.
Note:The overboost feature controls a variety of engine parameters to
deliver additional torque. Overboost is built into the engine calibration on
the Focus ST and no action is required by the driver to engage.

WHEELS
Wheel Specifications
Diameter and width 18 inches x 8.0 inches
Offset 55 mm
Backspacing 6.673 inches
Center bore 63.3 mm
Weight 25 lbs (11 kg)
Your ST vehicle is equipped with unique wheels matched to the tires.
These wheels are more susceptible to damage due to their diameter,
width and low profile tires. To avoid damage to your wheels:
•Maintain proper tire pressure.
•Exercise caution when using automated, commercial car washes. Hand
washing or using touchless commercial car washes without mechanical
tracks is the best way to avoid potential damage.
•When installing wheels, always torque lug nuts to specification with a
torque wrench.
•Inspect your wheels for damage on a regular basis. If a wheel is
damaged, replace it immediately.
•In the event that you encounter an abnormally harsh impact, inspect
the outer diameter of your wheels, both inside and out, for damage.
WHEEL LUG NUT TORQUE SPECIFICATIONS
WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make sure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.

Your ST vehicle is equipped with low profile, high performance tires that
are designed to optimize the driving dynamics you expect in a ST
vehicle. These tires are not optimized for off-road or winter (snow or
cold weather) performance, and their ride, noise and wear characteristics
are different than non-performance tires. Also, because of their lower
profile, the tires are more susceptible to damage due to potholes and
rough roads. To make sure that your tires perform as intended, it is
important that you maintain your tires properly:
•Note:Do not use tire chains on the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•Do not overload your vehicle. Maximum vehicle and axle weights are
listed on the tire information placard.
•Extra caution should be taken when operating the vehicle near its
maximum load, including assuring proper tire pressure and reducing
speeds.
•Extra caution should be taken when operating on rough roads to avoid
impacts that could cause tire damage.
•In the event that you encounter an abnormally harsh impact, inspect
your tires for damage.
