LOW FUEL PRESSURE SEE MANUAL (diesel engine only)—If
this message appears during a cold start or during cold operation 32°F
(0°C) up to 10 minutes after the initial cold start; monitor the message
center and if it disappears and does not re-appear after the engine has
fully warmed up, the low fuel pressure message is most likely caused by
waxed or gelled fuel. To prevent this, use an anti-gel additive. Refer to
your diesel supplement for more information. The customer warranty
may be void from using additives that do not meet or exceed Ford
specifications. If the low fuel pressure message persistently appears after
re-fueling during the cold start and cold operation conditions defined
previously and then disappear when the engine has fully warmed up,
consider different fuel sources.

•Low Fuel Operation: If the message appears when the vehicle is warm
and during low fuel tank level operation, i.e. the tank level is at or
very near empty, refuel the vehicle and operate the vehicle. If the
message reappears after fueling, see below. If the message does not
come back, the low fuel pressure condition was due to low fuel levels
in the fuel tank.
•Normal Operation: If the message appears during normal operation
when the vehicle / engine is fully warm, and fuel level is not low, the
fuel filters must be changed regardless of the maintenance schedule
interval. If replacement of the fuel filter does not remedy the low fuel
pressure message during normal operation as defined above, please
take the vehicle to your authorized dealer.

Your vehicle’s message center is capable of monitoring many vehicle
systems and will alert you to potential vehicle problems and various
conditions with a informational messages and/or warnings.
The message center is also used to program/configure the different
features of your vehicle.
The message center display is located in the instrument cluster. Use the
steering wheel mounted buttons to navigate through the message center.
Press the up/down buttons to move
up/down through the message

TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
WARNING:The tire pressure monitoring system is NOT a
substitute for manually checking tire pressure. The tire pressure
should be checked periodically (at least monthly) using a tire gauge,
seeInflating your tiresin this chapter. Failure to properly maintain
your tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on the vehicle placard or tire
inflation pressure label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated.
This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be
able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of

1. Pull off the road as soon as safely possible and place the vehicle in P
(Park).
2. Leave the engine running until the coolant temperature gauge needle
moves away from the H range. After several minutes, if this does not
happen, follow the remaining steps.
3. Turn the engine off and wait for it to cool before checking the coolant
level.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
4. If the coolant level is normal, you may restart your engine and
continue on.
5. If the coolant is low, add coolant, restart the engine and take your
vehicle to an authorized dealer. SeeAdding engine coolantin this
chapter for more information.
Refer to fail-safe cooling for additional information.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter (gasoline vehicles only)
that is integrated with the fuel tank. Regular maintenance or
replacement is not needed. For diesel engine information, refer to the
diesel supplement.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
WARNING:Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and fire.
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
