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.
SHIFTLAMP and SHIFTTONE can be used separately, together, or
turned off completely.
To use the performance shift indicator feature,first bring the vehicle
to a complete stopthen use the message center controls as follows:

•Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of recycled engine coolantsection).
WARNING: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.
Coolant and intercooler 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 coolant reservoir as
previously outlined.
2. Slowly add a50/50 mixtureof coolant and distilled water to the
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 coolant reservoir as
previously outlined.
7. Add a50/50 mixtureof coolant and distilled water to the coolant
reservoir until the coolant level is at the “cold fill range” 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).
