•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least three
feet (one meter) away from another
Ford Motor Company vehicle
undergoing the system reset procedure
at the same time.
• Do not wait more than two minutes
between resetting each tire sensor or
the system will time-out and the entire
procedure will have to be repeated on
all four wheels.
• A double horn will sound indicating the
need to repeat the procedure.
Performing the System Reset Procedure
(Single Rear Wheel)
Read the entire procedure before
attempting.
1. Drive the vehicle above 20 mph
(32 km/h) for at least two minutes,
then park in a safe location where you
can easily get to all four tires and have
access to an air pump.
2. Place the ignition in the off position and
keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. You must accomplish this
within 10 seconds. If the reset mode
has been entered successfully, the horn
will sound once, the system indicator
will flash and a message is shown in
the information display. If this does not
occur, please try again starting at Step
2. If after repeated attempts to enter
the reset mode, the horn does not
sound, the system indicator does not
flash and no message is shown in the
information display, seek service from
your authorized dealer. 5. Train the tire pressure monitoring
system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following clockwise order: Left front
(driver's side front tire), Right front
(passenger's side front tire), Right rear
(passenger's side rear tire), Left rear
(driver's side rear tire).
6. Remove the valve cap from the valve stem on the left front tire. Decrease the
air pressure until the horn sounds.
Note: The single horn chirp confirms that
the sensor identification code has been
learned by the module for this position. If a
double horn is heard, the reset procedure
was unsuccessful, and you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease
the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire. Decrease the
air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire. Decrease the
air pressure until the horn sounds.
Training is complete after the horn
sounds for the last tire trained (driver's
side rear tire), the system indicator
stops flashing, and a message is shown
in the information display.
10. Turn the ignition off. If two short horn
beeps are heard, the reset procedure
was unsuccessful and you must
repeat it. If after repeating the
procedure and two short beeps are
heard when the ignition is turned to
off, seek assistance from your
authorized dealer.

11.
Set all four tires to the recommended
air pressure as indicated on the
Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door
edge that meets the door-latch post,
next to the driver's seating position)
or Tire Label located on the B-Pillar
or the edge of the driver's door.
Performing the System Reset Procedure
(Dual Rear Wheel)
For further information see
Understanding Your Tire Pressure
Monitoring System and refer to Dual
Rear Wheel, earlier in this section.
Read the entire procedure before
attempting.
1. Drive the vehicle above
20 mph
(32 km/h) for at least two minutes,
then park in a safe location where you
can easily get to all six tires and have
access to an air pump.
2. Place the ignition in the off position and
keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. You must accomplish this
within 10 seconds. If the reset mode
has been entered successfully, the horn
will sound once, the system indicator
will flash and a message is shown in
the information display. If this does not
occur, please try again starting at Step
2. If after repeated attempts to enter
the reset mode, the horn does not
sound, the system indicator does not
flash and no message is shown in the
information display, seek service from
your authorized dealer. 5. Train the tire pressure monitoring
system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following order: Left front (driver's side
front tire), Right front (passenger's side
front tire), Right outer rear (passenger's
side rear outer tire), Right inner rear
(passenger's side rear inner tire), Left
outer rear (driver's side rear outer tire),
Left inner rear (driver's side rear inner
tire).
6. Remove the valve cap from the valve stem on the left front tire. Decrease the
air pressure until the horn sounds.
Note: The single horn chirp confirms that
the sensor identification code has been
learned by the module for this position. If a
double horn is heard, the reset procedure
was unsuccessful, and you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease
the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right outer rear tire.
Decrease the air pressure until the horn
sounds.
9. Remove the valve cap from the valve stem on the right inner rear tire.
Decrease the air pressure until the horn

Trailer Tire Pressure Monitoring
System (If Equipped)
Note: Additional equipment may be
required for your vehicle to support trailer
tire pressure monitoring. See your authorized
dealer for more information.
Note: The trailer tire pressure monitoring
system is not a substitute for proper tire
maintenance. It is your responsibility to
maintain correct tire pressures at all times.
Note: If a trailer tire is repaired, replaced or
broken down for service, the screw and valve
on the trailer tire pressure sensor should be
replaced. See your authorized dealer for
details. The trailer tire pressure monitoring system
is an added safety feature that allows you
to view your trailer tire pressures through
the information display. See
General
Information (page 113). Tire pressure
sensors are mounted into each tire on your
trailer. The sensors send a message to your
vehicle indicating the current trailer tire
pressure.
If the trailer tire pressure monitoring
system detects that a tire is low, a warning
message appears in the information
display. The trailer tire pressure status
screen in the information display highlights
the tire with a low pressure.
The main function of the trailer tire
pressure monitoring system is to warn you
when your trailer tires need air. It can also
warn you in the event the system is no
longer capable of functioning as intended.
See
Information Messages (page 129).
When a Temporary Spare or New Tire
is Installed
If you have replaced a trailer tire with a new
or spare tire, a warning message appears
and pressure readings are no longer
displayed for that tire.
To restore the full function of the trailer
tire pressure monitoring system:
• Have the damaged wheel and tire
assembly repaired and remounted to
your trailer.
• Install the trailer tire pressure
monitoring sensor into the new wheel
and tire assembly.
• Perform the trailer tire pressure
monitoring system reset procedure.
Trailer Tire Pressure Monitoring
System Reset Procedure
Note: You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation, or when a new trailer tire
pressure sensor is installed into a trailer tire.
