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.

Upshift
Illuminates when it is best to shift to the next highest manual
transmission gear to maximize fuel economy.
Multi Shift indicators:
1.
(Upshift): Set for maximum fuel economy
2.SVT: Performance Shift Indicator
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.

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.

•Do notdrive farther than 120 miles (193 km). Drive only to the
closest authorized dealer or tire dealer.
•Drive carefully and avoid abrupt steering maneuvers.
•Periodically monitor tire inflation pressure in the affected tire; if the
tire is losing pressure, have the vehicle towed.
•Read the information in theTips for use of the temporary mobility
kitsection to ensure safe operation of the temporary mobility kit and
your vehicle.
Tips for use of the temporary mobility kit
Read the following list of tips to ensure safe operation of the temporary
mobility kit:
•Before operating the temporary mobility kit, make sure your vehicle is
safely off the road and away from moving traffic.
•Always set the parking brake to ensure the vehicle doesn’t move
unexpectedly.
•Do not remove any foreign objects, such as nails or screws, from the
tire.
•When using the temporary mobility kit, leave the engine running
(only if the vehicle is outdoors or in a well-ventilated area)so
the compressor doesn’t drain the vehicle’s battery.
•Do not allow the compressor to operate continuously for more than
10 minutes; this will help prevent the compressor from overheating.
•Never leave the temporary mobility kit unattended when it is
operating.
•Keep the temporary mobility kit away from children.
•Only use the temporary mobility kit when the ambient temperature is
above –20°F (-29°C).
•Only use the temporary mobility kit for sealing/inflating the tires on
your vehicle. Do not use the kit for inflating tires on motorcycles,
bicycles or any other type of tire.
•Only use the sealing compound before the expiration date. The
expiration date is labeled on the unit.
•Do not store the temporary mobility kit inside the passenger
compartment of the vehicle as it may cause injury during a sudden
stop or collision. Store the kit in its proper location.

4. Loosen the safety latch (4) on
the sealing compound container (5)
and rotate the container until it is
upright and clicks into place.
5. Peel the speed limit sticker (6)
off the side of the container and
affix it to the center of the
instrument panel so it can be seen
in plain view. Do not place it over
any airbag cover.
6. Start the engine(only if the
vehicle is outdoors or in a
well-ventilated area)to prevent
the vehicle’s battery from draining.
Do not start your vehicle in
a closed garage or in other
enclosed areas. The carbon
monoxide in exhaust fumes can be
toxic. Always open the garage
door before you start the engine.
7. Turn the air compressor on by
pressing the “I” side of the orange
button.

Second stage: Checking tire pressure
1. Stop driving after approximately two miles. Then check the air
pressure of the damaged tire as follows:
•Ensure the compressor is turned off by pressing the “O” side of the
orange button.
•Remove the hose and the cable with the electrical plug from the kit’s
storage compartment.
•Remove the valve cap from the sealed tire, then screw the hose firmly
onto the tire’s air valve.
•Start the engine(only if the vehicle is outdoors or in a
well-ventilated area)to prevent the vehicle’s battery from draining.
•Insert the electrical plug into the vehicle’s power point.
•Read the air pressure gauge on the temporary mobility kit.

What to do after the tire has been sealed
After using the temporary mobility kit to seal your tire, you will need to
replace the sealing compound and hose. Sealing compound and spare
parts can be obtained and replaced at an authorized dealer or tire dealer.
Empty sealing compound bottles may be disposed of at home; however,
liquid residue from the sealing compound should be disposed by your
authorized dealer or tire dealer, or in accordance with local waste
disposal regulations.
Note:After the sealing compound has been used, the maximum vehicle
speed is 50 mph (80 km/h) and the maximum driving distance is
120 miles (193 km). The sealed tire should be replaced immediately, or
at least within the 120 miles (200 km). After sealant use, the TPM (Tire
Pressure Monitoring) sensor located inside the wheel, must be replaced
by an authorized Ford dealer.
Note:If you experience any unusual vibration, ride disturbance or noise
while driving, reduce your speed until you can safely pull off to the side
of the road to call for roadside assistance.
You can check the tire pressure any time within the 120 miles (193 km)
by performing the following:
1. Ensure the compressor is turned off by pressing the “O” side of the
orange button.
2. Remove the hose and the cable with the electrical plug from the kit’s
storage compartment.
3. Remove the valve cap from the sealed tire, then screw the hose firmly
onto the tire’s air valve.
4. Insert the electrical plug into the vehicle’s power point.
5. Start the engine(only if the vehicle is outdoors or in a
well-ventilated area)to prevent the vehicle’s battery from draining.
6. Read the air pressure gauge on the temporary mobility kit.
If the tire pressure needs to be increased, operate the air compressor
and inflate the tire to the recommended pressure as indicated on the
label on the B-Pillar or the edge of the driver’s door.
