ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
AdvanceTracsport mode
The AdvanceTracsystem provides an available sport mode specially
calibrated for the Boss302 and its unique performance characteristics.
This can be selected utilizing the stability control off switch. While in
AdvanceTracsport mode, the selected steering option will be
overridden and placed in sport mode. See theDrivingsection of the
Owner’s Guidefor more information.
DRIVING YOUR VEHICLE THROUGH WATER
The Boss302 has aerodynamic devices attached to the underbody
designed to help control airflow for superior performance. Therefore, the
driver must be especially careful to avoid driving through deep or
standing water. If driving through deep or standing water is unavoidable,
proceed very slowly. Never drive through water that is higher than the
bottom of the wheel rims. Water may enter through the air intake due to
the vacuum generated in the engine. Damage caused by the intake of
water in the engine is not covered by the warranty. Refer toTi r e
informationfor more information.
GROUND CLEARANCE
Because of low vehicle ground clearance, use caution when
approaching curbs/curb stops from the front and rear as vehicle
damage will occur. Additionally, when crossing speed bumps or
driveway curbs, Ford recommends approaching at a very low
speed.

WASHING YOUR VEHICLE
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
not equipped to tow. No towing packages are available through
an authorized dealer.

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.).
