adjustment controls are located on
top of the damping rods and can be
adjusted with a small screwdriver.
Remove the cap to access the
control for the front strut.
To access the rear shock, pull the
carpet back in the trunk area. Then,
lift the trim panel and pull rearward
to expose the adjustable suspension
damper.
Position (1) has the lowest damping
force which provides for a more
comfortable ride. Position (5) has
the highest damping force which
provides more responsive handling.
Position (2) is the factory setting
(shown in graphic).
Left and right dampers should always be set to the same dial position.
Front and rear can be adjusted independently to change vehicle response.

WHEELS
Your Boss302 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 (seeTiresin this supplement).
•Do not drive your vehicle through an automated, commercial car wash
due to the vehicle’s low ground clearance, tire width and track width.
Wash your vehicle by hand, or by using a touchless commercial wash
with no mechanical tracks on the floor.
•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 edge of your wheels, both inside and out, for damage.
Operating at high speeds
Your Boss302 is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed, electronically limited to 155 mph
(250 km/h). Remember to drive safely, obey all traffic laws and only
operate your vehicle at high speeds at locations equipped and designed
to do so safely. Before operating your vehicle at high speeds:
•Ensure 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.
Wheel lug nut torque specifications
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.).

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. Ensure 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.
IMPORTANT TIRE INFORMATION
Your vehicle is equipped with unique wheels and tires designed to
enhance performance. To continue providing this performance, extra
care must be taken when operating and maintaining your vehicle.

Tires
Your Boss302 is equipped with low profile, high performance tires that
are designed to optimize the car’s driving dynamics. 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 ensure
that your tires perform as intended, it is important that you maintain
your tires properly.
•The Boss302 and Boss302 with Laguna Seca Package original
equipment tires are optimized for maximum steering and handling
performance. Ford does not recommend using these tires in cold
temperatures of approximately 40°F (5°C) and below (depending on
tire, surface and weather conditions). See your Ford dealer for
recommended tires in these conditions.

•The Boss302 with Laguna Seca Package is equipped with ultra
high-performance, dry weather-only summer tires that provide
superior steering and handling.
WARNING:If equipped with the Laguna Seca Package, never
drive with these tires in any wet conditions (rain, snow, ice, etc.)
because they cannot channel water away and will slide risking serious
injury.
•Do not use tire chainson the original wheels and tires of your
vehicle. The use of any type of tire chain on these tires may damage
your vehicle.
•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.
•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 ensure original performance is
to use the original equipment tire. If a different tire is used, it should
be the same size, speed rating and load rating and be replaced as a set
of four. Never mix tire brands.
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and
performance of your vehicle, which could result in an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
Additionally, the use of non-recommended tires and wheels could
cause steering, suspension, axle or transfer case/power transfer unit
failure.
Winter driving
The original equipment tires on your Boss302 are designed for high
performance steering and handling. They are not designed for winter use
on ice or snow and cannot be used with snow chains. If you will be
operating your vehicle in these conditions, winter or all-season tires must
be used.
Do not operate your vehicle above posted speed limits and never
perform high speed driving with winter tires, even in clear, dry driving
conditions.
Tire rotation
Because your vehicle is equipped with unique larger tires on the rear
wheels, you can only rotate the tires side to side. You must not rotate
tires in a crisscross pattern or front to rear. If you notice that the tires
wear unevenly, have them checked.
The tires on your Boss302 should be rotated every 5,000 miles
(8,000 km). This will help your tires wear more evenly, providing better
tire performance and longer tire life.

The optional Laguna Seca Package tires (255/40ZR19 front, 285/35ZR19
rear) are directional. Tire rotation is not recommended for directional
tires.

•Sometimes irregular tire wear can be corrected by rotating the tires.
•If your tires show uneven wear, ask an authorized dealer to check for
and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
•After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.

WRECKER TOWING
If you need to have your vehicle towed, contact your roadside assistance
center or a professional towing service.
It is recommended that your vehicle be towed with a wheel lift and
dollies or with flatbed equipment. When towing with a flatbed, 4x4
blocks must be used when loading/unloading your vehicle. Do not tow
with a slingbelt. Ford Motor Company has not approved a slingbelt
towing procedure.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
