ALTERNATE CALIBRATION
Your Shelby GT500 Power Train Control Module (PCM) strategy contains
a feature to limit supercharger boost pressure and engine speed to 4000
RPM for the first five consecutive miles of vehicle operation or 50 engine
start / warm up cycles. This feature is enabled prior to shipment. If
neither of these conditions have been satisfied prior to customer
delivery, full power will not be available.
MANUAL 6 SPEED TRANSMISSION OPERATION
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully depressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to 1st gear, then slowly release the clutch
pedal while slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Failure to fully depress the clutch pedal to the floor may cause increased
shift efforts, prematurely wear transmission components or damage the
transmission. Make sure the floor mat is properly positioned so it doesn’t
interfere with the full extension of the clutch pedal.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Due to the high performance of the powertrain, a certain amount of
noise from the transmission is normal. This noise will be most noticeable
when the vehicle is idling in neutral with the clutch pedal out but can
also occur when driving away from a stop.

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.
