Introduction
SVT HISTORY
The Ford Special Vehicle Team (SVT) was established in 1991 to “Polish
the Ford Oval” by creating low-volume, factory-produced vehicles
designed for those select few whose idea of driving is a high-powered,
passionate experience — not just a means of getting from point A to
point B.
In a move to support this spirited enthusiasm, Ford Motor Company
carefully integrated the wide array of talent in the company into a small,
cross-functional group of engineers, product planners and marketing
people, housed together under one roof with a common mission: to
create vehicles specifically designed to meet the unique needs and
desires of the knowledgeable driving enthusiast.
Each of nearly 150,000 SVT vehicles produced since the 1993 model year
has been designed and developed with the four SVT Hallmarks in mind:
Performance, Substance, Exclusivity and Value. These hallmarks have
driven the SVT Mustang Cobra and the Cobra R, the SVT F-150
Lightning, the SVT Contour, the SVT Focus, and now the Shelby GT500.
We are proud and passionate about what we do, and we’re glad you have
made us your choice.

Performance Shift Indicator
Your vehicle is equipped with a programmable Performance Shift
Indicator. When activated, this feature provides a visual (SHIFTLAMP)
and /or audible (SHIFTTONE) cue to shift to the next highest gear at an
engine rpm specified by the driver.
The SHIFTLAMP feature uses the SVT logo on the tachometer to notify
you when the desired shiftpoint is reached. The SVT symbol is backlit in
red under normal driving conditions (SHIFTLAMP OFF). When the
SHIFTLAMP is set to ON, the red backlighting is turned off and the SVT
logo will turn bright orange when the desired shift point is reached.
The SHIFTTONE feature uses an audible tone to notify you when the
desired shiftpoint is reached.

Message Center
The following are possible messages you may see in your Shelby GT500
Message Center:
CHECK TRACTION CONTROL™: Displayed when the Traction
Control™ system is not operating properly. If this message is displayed
on the message center, the Traction Control™ system will be partially
operable. If this warning stays on, contact your dealer for service as soon
as possible. For further information, refer to Traction Control™ in the
Driving chapter in your Owner’s Guide.
TRACTION CONTROL™ ACTIVE: Displayed when the Traction
Control™ system is active. For further information, refer to Traction
Control™ in the Driving chapter in your Owner’s Guide.
Note: When traction control is turned off, it is possible to lose traction.
If you attempt to shift with the rear wheels spinning with a loss of
traction, it is possible to cause damage to the transmission. Do not
attempt to shift when the rear wheels do not have traction. Damage
caused by misuse of the vehicle is not covered.
ENGINE FAIL SAFE MODE: Displayed when the engine has defaulted
to a ’limp-home’ operation. If the warning stays on or continues to come
on, contact your dealer as soon as possible.
Unique instrument cluster lighting
Your vehicle is equipped with a unique instrument cluster color display.
In place of ORANGE, you can select R-W-B which will illuminate the
speedometer in RED, the Fuel/Boost/Temp/Oil Pressure gauges in
WHITE and the tachometer in BLUE. (Pointer colors are not adjustable).
The instrument cluster will momentarily display the R-W-B coloring when
the ignition is turned to ON or START and will then return to the
previously chosen color.
For instructions on how to set the instrument cluster display color or
MyColor™, refer to Message Center — Display Color in the Driver
Controls chapter in the Owner’s Guide.

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.

Driving your Shelby GT500
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 (see Tires in 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.

Chassis
Operating at high speeds
Your SVT vehicle is capable of high speeds and is equipped with tires
rated for the vehicle’s maximum speed. Remember to drive safely, obey
all traffic laws and only operate your SVT vehicle at high speeds at
locations equipped and designed to do so safely. Before operating your
vehicle at high speeds:
• Ensure correct tire pressures (see Tires in 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.).
Bolt size Wheel lug nut torque*
lb.ft. N•m
1
⁄2x 20 100 135
* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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 SVT 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.
