The Performance Shift Indicator feature functions independently of the
fuel economy Upshift Indicator (
). The Upshift Indicator will still
illuminate when it is best to shift to the next highest gear to maximize
fuel economy regardless of the Performance Shift Indicator Settings.
Message Center
The following are possible messages you may see in your Shelby GT500
Message Center:
CHECK TRACTION CONTROL: Displayed when the Traction
Controlsystem is not operating properly. If this message is displayed
on the message center, the Traction Controlsystem will be partially
operable. If this warning stays on, contact your dealer for service as soon
as possible. For further information, refer toTraction Controlin the
Drivingchapter in yourOwner’s Guide.
TRACTION CONTROLACTIVE:Displayed when the Traction
Controlsystem is active. For further information, refer toTraction
Controlin theDrivingchapter in yourOwner’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 toMessage Center — Display Colorin theDriver

To reduce the risk of personal injury, make sure the engine is
cool before unscrewing the coolant pressure relief cap. The
cooling system is under pressure; steam and hot liquid can come out
forcefully when the cap is loosened slightly.
If you must remove the pressure relief cap or radiator cap (depending
upon engine application), follow these steps to avoid personal injury:
1. Before you remove the cap, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the cap. Slowly
turn cap counterclockwise until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
Engine coolant refill procedure
The following procedure should be used when refilling the cooling
system after it has been drained or become extremely low.
1. Remove the pressure relief cap from the engine coolant reservoir as
previously outlined.
2. Slowly add a50/50 mixtureof engine coolant and distilled water to
the engine coolant reservoir until the coolant level is at the “cold fill
level” as listed on the reservoir.
3. Reinstall the pressure relief cap.
4. Start and idle the engine until the upper radiator hose is warm (this
indicates the thermostat is open and coolant is flowing through the
entire system).
5. Shut the engine off and let it cool.
6. Remove the pressure relief cap from the engine coolant reservoir as
previously outlined.
7. Add a50/50 mixtureof engine coolant and distilled water to the
engine coolant reservoir until the coolant level is at the “cold fill level” as
listed on the reservoir.
8. Reinstall the pressure relief cap.
9. Check the coolant level in the reservoir before you drive your vehicle
the next few times (with the engine cool).
10. If necessary, add a50/50 mixtureof engine coolant and distilled
water to the engine coolant reservoir until the coolant level is at the
“cold fill level” as listed on the reservoir.
