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)
4 - 5 41 mph (66 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.

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.

Retighten the lug nuts to the specified torque at 500 miles (800 km)
after any wheel disturbance (tire rotation, changing a flat tire, wheel
removal, etc.).

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.

•Inspect your tires for damage on a regular basis. If a tire is damaged,
replace it immediately.
•Proper suspension alignment is critical for maximum performance and
optimal tire wear. If you notice uneven tire wear, have your alignment
checked.
•When replacing tires, the only way to maintain original performance is
to use the original equipment tire. If a different summer tire is used, it
should be the same size, speed rating and load rating as the originally
equipped tire. Tires should be replaced as a set of four. Never mix tire
brands or models.
TIRE PRESSURE
•For tire pressures, see the placard located on the B-pillar inside the
driver’s door.
•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, using an accurate gauge.
•Tire pressures are specified “cold” and should be checked after the
vehicle has been parked for at least 3 hours. Do not reduce pressure
of warm tires.
•Check your tire pressure often to maintain it properly. Tire pressure
can diminish over time and fluctuate with temperature.
WINTER DRIVING
The original equipment tires on your ST vehicle are designed for
maximum performance in dry and wet summer conditions. They are not
designed for winter use on ice or snow and cannot be used with snow
chains. Ford does not recommend using the original equipment tires
when temperatures drop to approximately 40°F (5°C) or below
(depending on tire wear and environmental conditions) or in snow/ice
conditions. If you will be operating your vehicle in these conditions,
winter or all-season tires must be used.
•Even with clear, dry driving conditions do not operate your vehicle
above posted speed limits or perform high speed maneuvers with
winter tires.
•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.

The following table lists acceptable tire sizes for winter tires. Tire speed
and load ratings should match those of the originally equipped tires as
closely as possible. If it is required to fit winter tires with a speed rating
less than the original equipment tires (to fit snow chains, for example),
be aware of the maximum speed rating for the tire and never exceed.

Please call the Ford Performance Info Center at 1-800-FORD-SVT
(367-3788) for specific winter tire recommendations.
FULL SIZE SPARE
Your Focus ST is equipped with a full size, dissimilar spare tire assembly.
Although the spare is a traditional, full size tire (as opposed to a mini
spare), it is different in both size and handling characteristics from the
standard Focus ST performance tire. Should you need to install the spare
tire, the following precautions must be adhered to:
•Because of the different performance characteristics of the spare tire,
avoid aggressive steering, braking, acceleration or high speeds when
the spare tire is installed.
•Never enable ESC Sport mode or fully disable ESC when the spare
tire is installed
•Replace the spare tire with the correct original equipment specified
tire as soon as possible
The following table lists the specifications for the full size spare tire and
wheel assembly. Tire speed and load ratings should match those of the
originally equipped tires as closely as possible.
