Your vehicle is equipped with a twin disc cera-metallic clutch. This
clutch incorporates racing technology to combine a low inertia clutch
assembly with a very durable friction material with high torque
capability. Depending on your driving technique, the smoothness of how
the vehicle reacts to clutch engagement may be different from other
vehicles you have driven. This behavior is typical of a cera-metallic
clutch and is not indicative of any abnormal issues with your vehicle.
DRIVING YOUR SHELBY GT500 THROUGH WATER
The Ford Shelby GT500 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.
GROUND CLEARANCE
Note: Because of low vehicle ground clearance, use caution when
approaching curbs/curb stops from the front and rear as vehicle
damage could occur.

WASHING YOUR SHELBY GT500
Do not drive your vehicle through an automated, commercial car
wash due to the vehicle’s low ground clearance, tire width and
track. Wash your vehicle by hand, with a commercial wand, or by
using a touchless commercial wash with no mechanical tracks on
the floor.

WHEELS
Your SVT 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 (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. Wash
your vehicle by hand, with a commercial wand, 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 diameter of your wheels, both inside and out, for damage.
