warning FORD MUSTANG 2013 5.G Boss 302 Supplement Manual

WASHING YOUR VEHICLE
Note: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. Do not use a commercial or
high pressure wand on the striped surfaces or stripe edges.
TRAILER TOWING
WARNING:Never tow a trailer with this vehicle. Your vehicle is

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
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.

cause steering, suspension, axle or transfer case/power transfer unit
failure.

The Mustang Boss 302 Laguna Seca package includes D.O.T. approved
ultra high-performance summer tires with track capability. The rubber
compounds used in these tires lose flexibility and may develop surface
cracks in the tire tread area at temperatures below 20°F (-7°C). Always
store your tires indoors at temperatures above 20°F (-7°C). If the tires
have been subjected to 20°F (-7°C) or less, warm them in a heated space
to at least 40°F (5°C) for at least 24 hours before installing them on a
vehicle, or moving the vehicle with the tires installed, or checking tire
inflation. Do not place tires near heaters or heating devices used to
warm the room where the tires are stored. Do not apply heat or blow
heated air directly on the tires. Always inspect the tires after storage
periods and before use as outlined in the owner’s manual. Ford does not
recommend using the high performance summer tires on your Boss 302
or Boss 302 Laguna Seca edition when temperatures drop to
approximately 40
oF(5oC) or below, or in snow/ice conditions.
WARNING:If equipped with the Laguna SecaPackage, 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.
•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.
•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.

TRACK PREPARATION
The Boss302 and Boss302 Laguna Secaedition have been rigorously
proven out on race tracks. Below are recommendations for optimizing
your Boss302 for a track day event.
•For optimal performance, premium fuel is recommended.
•Change brake fluid to Super DOT 4 to improve track performance of
braking system (WSS-M6C65-A2), Ford part number (YS4Z-19542-
AA).
•Install Ford Racing front brake cooling kit (M-2004-MB) to improve
brake cooling (standard on Laguna Secaedition).
•Remove rear brake dust shields to improve brake cooling.
•Install Ford Racing transmission cooling scoop (M-5025-MBR) to
improve transmission cooling (standard on Laguna Secaedition).
•During extended track sessions in extreme temperatures or
conditions, your Boss 302 may require additional engine cooling
actions. If the water temperature warning light illuminates, return to
the paddock and let the vehicle return to normal operating
temperature while idling before turning the engine off. Prior to the
next session, remove the round fog light delete covers from the upper
grille. This wi ll allow more cooling air to the radiator and allow the
car to run extended sessions in extreme heat. Visit fordracing.com for
additional parts to further enhance the powertrain cooling on your
Boss 302.
•For extended track use, Ford recommends installing a rear differential
cooler to improve rear axle cooling.
•The Ford Racing front splitter kit (M-16601P-MBA, standard on
Laguna Secaedition) can be installed to improve high-speed vehicle
stability and handling. If the Ford Racing front splitter kit will be
installed on a Boss 302 without the Laguna Secapackage, Ford
recommends installing the Laguna Secaedition rear spoiler in place
of the standard rear spoiler to maintain aerodynamic balance. The
unique lower grille from the Laguna Secaedition should also be
installed to accommodate the splitter support rods. This front splitter
is intended for race track use only and is not legal for on-street
driving. It may degrade crash performance and void the vehicle
warranty. The front splitter must be installed by the customer.
