transmission gear to maximize fuel economy.
Multi Shift indicators:

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.
