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.

WARRANTY COVERAGE
The Shelby GT500 carries the same New Vehicle Limited Warranty as
other Ford Mustang models. This information is covered in its entirety in
the Ford Motor Company Warranty Guide.
Warranty service for the Shelby GT500 or any SVT vehicle can be
obtained at any Ford or Lincoln Mercury dealer nationwide.
SVT does not recommend modifying or racing SVT vehicles, as they are
designed and built to be driven as delivered from the factory. The Ford
Motor Company Warranty Guide discusses vehicle usage and the
installation of aftermarket parts and their effect on warranty coverage as
follows:
Repairs are not reimbursable under warranty when damage is caused by:
•misusing the vehicle, such as driving over curbs, overloading, racing,
or using the vehicle as a stationary power source.
•altering or modifying the vehicle — including the body, chassis, or
components — after the vehicle leaves Ford’s control.
•non-Ford parts installed after the vehicle leaves Ford’s control,
including, but not limited to, cellular phones, alarm systems and
automatic starting systems.
Please see the Warranty Guide for complete information.
In the event the vehicle is intended for track use, and the loss of
warranty coverage is not of concern, the following powertrain durability
modifications are recommended:
•install transmission oil cooler. Permanent damage to the transmission
will result if the vehicle is subjected to competition conditions without
installation of a transmission oil cooler.
•install rear differential cooler. Permanent damage to the rear
differential will result if the vehicle is subjected to competition
conditions without installation of a differential cooler.
Additionally, perform Multi-Point Inspection and the inspections outlined
in the 120,000 mile Normal Maintenance Schedule outlined in the
Scheduled Maintenance Guide. Refer to the Vehicle Service Manual for
removal and installation procedures. Replace with Genuine Ford and
Motorcraft service parts as needed.
These modifications will not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications will render repairs
non-reimbursable under the New Vehicle Limited Warranty.
