Uplevel message center
Note:Some warning lights are
reconfigurable telltale (RTT)
indicator lights and will illuminate in
the message center. These lights
function the same as the other
warning lights. The first three
positions will only display one
warning telltale at a time; the last
three positions can cycle between
different warning telltales.
Service engine soon:The service
engine soon indicator light
illuminates when the ignition is first
turned to the on position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, the service engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds the service engine
soon light blinks eight times, it means that the vehicle is not ready for
I/M testing. See theReadiness for Inspection/Maintenance (I/M)
testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.

Powertrain malfunction/Reduced
power/Electronic throttle
control (RTT):Displays when the
engine has defaulted to a
“limp-home” operation or when a transmission problem has been
detected and shifting may be restricted. If the light remains on, have the
system serviced immediately by your authorized dealer.
Check 4X4 (RTT) (if equipped):
Displays with the message CHECK
4X4 when a four-wheel drive fault is
present.
Refer toMessage centerin this chapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
when the engine is not running, or in a position between on and start, or
by applying the parking brake when the ignition is turned to the on
position.
If the brake system warning light does not illuminate at this time, seek
service immediately from your authorized dealer. Illumination after
releasing the parking brake indicates low brake fluid level and the brake
system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12V DC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,
•do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
Power point (110V AC) (if equipped)
The 110V AC power point outlet is used for powering electrical devices
that require up to 150W. Exceeding the 150W limit will cause the power
point to cut off the power temporarily to provide overload protection.
Note:The 110V AC power point is
equipped with a cap which provides
protection from inserting objects
into the socket. The cap should
always be in a closed position
whenever the power point outlet is
not in use.
The 110V AC power point is located
on the back of the center console.
The power outlet is not designed for the following electric appliances;
they may not work properly:
•Cathode ray tube type televisions
•Motor loads, such as vacuum cleaners, electric saws and other electric
power tools, compressor-driven refrigerators, etc.
•Measuring devices, which process precise data, such as medical
equipment, measuring equipment, etc.
•Other appliances requiring an extremely stable power supply:
microcomputer-controlled electric blankets, touch sensor lamps, etc.

Using MyKeywith remote start systems
MyKeyis not compatible with non Ford-approved aftermarket remote
start systems. If you choose to install a remote start system please see
your authorized dealer for a Ford approved remote start system.
The following information MAY help customers who choose to use a non
Ford-approved remote start system. The actions proved below do not
make MyKeycompatible with non Ford-approved remote start system,
but it MAY help you to retain some MyKeyfunctions.
Vehicles equipped with traditional keys
When using a non Ford-approved remote start system, the default settings
may recognize the remote start system as an additional admin key with its
associated privileges. This makes it NOT compatible with MyKey. The
following action may help you to retain some MyKeyfunctions:
1. Restart the engine when you insert a key into the ignition cylinder.
2. In addition to the key that you have already programmed as a
MyKey, owners of vehicles equipped with traditional keys may want to
program the non Ford-approved remote start system as a MyKeyif the
remote start fob is used by the MyKeydriver.
To program a non Ford-approved remote start system as MyKey,dothe
following:
1. Enter the vehicle and close all doors.
2. Remote start the vehicle using a remote start fob.
3. Follow steps 1-4 in theCreate a MyKeysection.
Vehicles equipped with intelligent access key (push button start)
•It is not possible to program any remote start system as MyKeyon
vehicles equipped with an intelligent access key (push button start).
Therefore, you should treat the remote start fob as you would any
other admin key. When the vehicle is started using remote start, the
system will stall the engine when you either enter the vehicle or shift
the vehicle into gear. Prior to the engine stall, the vehicle will have
administrative privileges. When you restart the engine, the vehicle will
identify the user as an admin or MyKeydrive depending on the
settings of the actual key used to start the vehicle.
Note:For all vehicles, the number of MYKEY(S) PROGRAMMED or
ADMIN KEYS PROGRAMMED that is displayed in the MyKeysystem
status menus will include the non Ford-approved remote start system as
an additional key in the total count. See theCheck MyKeysystem
statussection.
