The Performance Shift Indicator feature functions independently of the
fuel economy Upshift Indicator (

illuminate when it is best to shift to the next highest gear to maximize
fuel economy regardless of the Performance Shift Indicator Settings.

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

ENGINE OIL RECOMMENDATION
Use Motorcraft SAE 5W-50 full synthetic or an equivalent SAE 5W-50 full
synthetic oil meeting Ford specification WSS-M2C931-B.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the Scheduled Maintenance Guide.
ENGINE AND INTERCOOLER COOLANT
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -36°C (-34°F). Coolant concentration testing
is possible with a hydrometer or antifreeze tester (such as the Rotunda
Battery and Antifreeze Tester, 0014–R1060). The level of coolant should
be maintained at the “cold full” of “cold fill range” level in the coolant
reservoir. If the level falls below, add coolant per the instructions in the
Adding Engine Coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•freeze protection down to -36°C (-34°F).
•boiling protection up to 129°C (265°F).
•protection against rust and other forms of corrosion.
•an accurate temperature readout from the engine coolant
gauge.
